Do UK Bank Accounts Have Routing Numbers? (2026)
UK bank accounts do not have routing numbers. They have sort codes, six digits instead of nine, and that is what the routing number box on an American form is actually asking for even though it does not say so.
The confusion is structural rather than careless. A routing number is a US instrument and only a US institution can hold one: the American Bankers Association restricts them to a federal or state chartered financial institution eligible for a master account at a Federal Reserve Bank. No British bank qualifies, so none has one.
What trips people up is that the answer changes depending on where the payment starts. A payment inside Britain wants a sort code and account number. A payment from abroad wants an IBAN and a BIC, and the sort code is already buried inside the IBAN rather than being replaced by it.
This guide covers what a UK account actually has, what each number identifies, the exact structure of a UK IBAN, what to type into a US wire form field by field, and what happens when the numbers do not match.
Sending Money to a UK Bank Account: The Short Answer
For a payment inside the UK you need a six digit sort code and an eight digit account number. For a payment from another country you need the IBAN and the BIC, also called the SWIFT code. There is no routing number in either case, and no UK bank can issue one.
Before you send anything, it is worth pricing the route. A bank wire and a specialist transfer to the same UK account can differ by a factor of ten once the exchange rate is counted, and the fee is usually the smaller half of the cost.
The comparison above runs live rates on the corridor you pick. The rest of this guide is about getting the numbers right so that whatever you send actually arrives.
What a UK Bank Actually Gives You
Two numbers, and they do different jobs. HSBC defines them precisely: a sort code is a 6 digit number that identifies your bank, and an account number is a unique 8 digit number that identifies your bank account. The sort code is typically printed on the back of your debit card, and both appear on statements, on cheques and in online banking.
That pair is complete for anything domestic. It is what you give a UK employer for your salary, what you type into a UK banking app to pay someone, and what our guide to transferring money between UK accounts is built around.
What a US Bank Asks You For
An international wire form wants the recipient's full name, the IBAN and the BIC or SWIFT code, and often the bank's name and address. HSBC states that senders generally need the IBAN and BIC or SWIFT code. It does not want a sort code on its own and it does not want a routing number, because neither will route a payment across a border.
If the form insists on a nine digit routing number and will not proceed without one, you are on the domestic transfer page rather than the international one. That is the single most common wrong turn, and it is worth backing out rather than forcing a number into it.
The Details That Make a UK Payment Domestic
Every number on this page exists because the payment is crossing a border. Give the sender UK details instead and most of it stops applying.
- A real UK sort code and account number: not a workaround, actual local details the sender treats as a normal UK payment
- US details as well: so money going the other way is a domestic US payment rather than an inbound wire
- Arrives in seconds, not days: a UK payment runs on Faster Payments instead of through correspondent banks
- No BIC, no IBAN, no wire fee: because there is no international leg left to charge for
Do UK Bank Accounts Have Routing Numbers?
No. The question do UK bank accounts have routing numbers has a clean answer for a structural reason: the ABA routing number is issued only to US institutions eligible for a Federal Reserve master account, so a British bank cannot hold one even in principle. The sort code is the functional equivalent.
No, and the Sort Code Is Why
Britain solved the same problem first and differently. The routing number exists, as the American Bankers Association puts it, to get payments to the right bank, and there are roughly 22,000 active nine digit numbers in the United States, administered by LexisNexis Risk Solutions as official registrar. The UK does the identical job with a six digit sort code and has done for decades.
So a UK bank routing number is not a thing that has been withheld from you or that a call to the bank will produce. It does not exist, and the person on the phone will tell you the sort code, which is the correct answer to the question you were really asking.
Six Digits Against Nine
The difference in length is the reason forms reject the substitution. A routing number field validates for nine digits. A sort code is six. Typing one into the other either fails immediately or, worse, passes a lax form and fails later in the payment chain, where the money comes back days afterwards minus whatever the banks in the middle deducted.
What it is called in the US | The UK equivalent | Digits | What it identifies |
|---|---|---|---|
ABA routing number | Sort code | 9 against 6 | The bank, and in the UK the branch |
Account number | Account number | Varies against 8 | The account itself |
Wire transfer | Telegraphic transfer or CHAPS | n/a | The same payment, different name |
No equivalent | IBAN | 22 characters | The account, internationally |
No equivalent | BIC or SWIFT code | 8 or 11 | The bank, internationally |
What Is a Bank Routing Number in the UK Sense?
Asked as what is a bank routing number in the UK, the honest translation is the sort code, and the honest extension is that for anything crossing a border the UK uses two numbers where the US uses one. The BIC identifies the bank internationally and the IBAN identifies the account. The routing number does both jobs at once inside the United States and neither of them outside it.
That asymmetry is the whole of the confusion. An American sender is looking for one number because one number is all they have ever needed. A British account has a different number for each job.
If a Form Will Only Take Nine Digits
A field that validates for nine digits is not going to accept a sort code, and there is no trick that makes it. It means the form is for domestic US payments, and the international transfer section is somewhere else on the same website, usually under wires or international.
Do not pad the sort code with zeros to reach nine digits, and do not put the sort code and account number together in one box unless the form explicitly says to. Both produce a payment that looks accepted and fails later, which is the expensive way to find out.
The Sort Code, Explained
A sort code is six digits, usually written as three pairs, and it identifies the bank and historically the branch that holds the account. It is the UK answer to the routing number and it is the number every domestic payment in Britain runs on.
What the Six Digits Identify
The first two digits identify the banking group, and the remaining four narrow it down within that group. In practice that means a sort code tells the payment system which institution to deliver to, in exactly the way nine digits do in the United States. HSBC describes it simply as the number that identifies your bank.
Branch level identification mattered more when payments were physical. Today most accounts are held centrally and the sort code functions as an institutional address rather than a geographic one, which is why two people at opposite ends of the country can share one.
Where to Find It
On the back of the debit card, on any statement, on a cheque, and in online or mobile banking. HSBC lists all four. It is not sensitive information in the way a card number is, because a sort code and account number let somebody pay money in rather than take it out.
That distinction is worth holding onto. Giving out a UK sort code and account number so that somebody can pay you is normal and safe, which is why they are printed on the outside of the card in the first place.
The Domestic Pair
Sort code plus account number is the complete set for any payment inside Britain, and that combination is what our guide to the bank details you need for a transfer covers across countries. For a UK to UK payment nothing else is required: no IBAN, no BIC, no reference beyond whatever the recipient asks for.
Note that this pair also survives a change of bank badly. If the recipient has moved banks, the old sort code and account number stop working, which is covered in our guide to switching bank accounts in the UK and matters more than people expect for payments arriving from abroad.
One more practical point about the pair. A UK sort code and account number do not travel with you. They belong to the bank, so leaving that bank means the details stop working, and anyone paying you from abroad has to be told the new ones. That is a small annoyance domestically and a real problem internationally, because an overseas payment sent to a closed account can spend a week finding its way back.
Details That Do Not Change When Your Bank Does
The alternative to reissuing your sort code every time you move bank is to hold details that are yours rather than the bank's.
- One set of UK details, kept: so an overseas payer is told once and never again
- Independent of any current account: switching your bank does not touch it
- Local details in other currencies too: dollars and euros alongside the pounds, each with its own details
- Free to open and hold: no subscription and no minimum balance
The UK IBAN, and Where the Sort Code Hides Inside It
A UK IBAN is 22 characters long and it is not a new number. Pay.UK sets out the structure as GB, two check digits, a four letter bank code taken from the first four characters of the BIC, then the six digit sort code, then the eight digit account number. Your existing numbers are inside it.
The 22 Characters, Broken Down
The specification is written as GBDD AAAA XXXX XXYY YYYY YY, where D is a check digit, A is the bank code, X is the sort code and Y is the account number. When an IBAN is sent electronically the separator spaces are dropped and it travels as one continuous string.
Position | Characters | What it is |
|---|---|---|
1 to 2 | GB | The country code |
3 to 4 | 2 digits | Check digits, calculated from the rest |
5 to 8 | 4 letters | Bank code, the first four characters of the BIC |
9 to 14 | 6 digits | The sort code |
15 to 22 | 8 digits | The account number |
A structurally valid example with an unassigned bank code and an all zero account, purely to show the shape, is GB56ZZZZ00000000000000. Never use a sample IBAN to send real money, because published examples frequently contain live bank codes.
Why the IBAN Is Not a New Number
This is the part that removes most of the anxiety. People assume they have to request an IBAN from the bank as a separate thing. They do not. The IBAN is derived from numbers the account already has, which is why banks can display it instantly in the app rather than issuing it.
The two check digits are the only genuinely new information, and they exist so that a typo fails validation before the payment leaves rather than after. That is the IBAN's main practical value over a bare sort code and account number.
The check digits are also why an IBAN is worth using even when a sender offers you the choice. A mistyped sort code is just six wrong digits that may still belong to a real bank. A mistyped IBAN fails the check digit calculation and is rejected before the money moves, which is a much better failure than a payment that leaves and does not arrive.
When You Need It and When You Do Not
You need it for money arriving from another country. You do not need it for anything domestic, and a UK banking app will usually not even ask. HSBC describes the IBAN as your account number written in a standard global format, which helps banks identify accounts held anywhere in the world so they can process international payments automatically.
If somebody in the UK asks you for an IBAN to pay you within the UK, they are overcomplicating it, and the sort code and account number will work.
SWIFT and BIC: the Bank's Address
A BIC is the bank's international identifier, 8 or 11 characters, and HSBC confirms that BIC and SWIFT code are the same thing under different names. Where the IBAN identifies the account, the BIC identifies the institution, and an international payment normally needs both.
What a BIC Is
HSBC spells out the naming: BIC stands for Business Identifier Code, also referred to as a Bank Identifier Code or a Bank International Code, and because these codes run on the SWIFT network people call them SWIFT codes. They are the same thing, and any form asking for one will accept the other.
The first four characters are the bank itself, which is why those same four characters appear inside the IBAN. The IBAN and the BIC are not independent pieces of information, they overlap deliberately.
BIC Against Routing Number
A BIC is the closer analogue to a routing number than a sort code is, in the sense that both identify an institution for the purpose of routing. The difference is scope: a routing number works inside the United States, a BIC works between countries, and a sort code works inside Britain.
So the complete translation is three numbers doing the job of one, split by geography. That is more moving parts, and more moving parts is more ways for a payment to go astray, which is the subject of our guide to receiving money from abroad.
Skip the Translation Entirely
The reason these numbers are confusing is that the payment is crossing a border. An account that holds both currencies means it does not have to.
- Local details on both sides: a UK sort code and account number, and US details too, so each payment is domestic at both ends
- No wire, no BIC, no IBAN needed: a payment into UK details is a UK payment, which arrives in seconds rather than days
- Mid-market exchange rate: fees published as a percentage starting from 0.24%, rather than folded into the rate
- Free to open and hold: no signup fee, no subscription and no minimum balance
- 40 currencies in one balance: convert when the rate suits you rather than when the payment forces it
What to Type Into a US Bank's Wire Form
Recipient name exactly as the UK bank holds it, the IBAN in the account or IBAN field, the BIC or SWIFT code in the bank identifier field, and the bank name and address where asked. Leave the routing number field alone, because an international wire form should not have one.
Field by Field
- Recipient name, spelled as the bank holds it, not a nickname
- IBAN, 22 characters for a UK account, no spaces
- BIC or SWIFT code, 8 or 11 characters
- Bank name and address, if the form asks, which some do and some do not
- Amount and currency, and note whether you are sending dollars or pounds, because that decides who converts
- Reference, only if the recipient asked for one
The currency choice on line five is the expensive one. Sending dollars hands the conversion to the UK bank at the other end at whatever rate it chooses. Sending pounds means your own bank converts, usually with the margin folded into the rate rather than shown as a fee. Our guide to what international wire transfers cost prices both directions.
If the Form Demands a Routing Number
Stop and find the international section. A form that requires nine digits is validating for a US domestic payment, and no UK detail will satisfy it. Most US banks keep domestic transfers and international wires on separate pages and the wording is often close enough to be misleading.
If your bank has no international wire option at all, that is a real limitation rather than a navigation problem. Some US institutions genuinely do not offer outbound international wires online, which is the situation our guide to banking between the US and the UK deals with.
Speed, and Why It Varies
A domestic UK payment usually arrives in seconds on Faster Payments. An international wire typically takes one to five business days because it passes through correspondent banks, which is set out in our guide to how long a wire transfer takes.
For a same day sterling payment inside the UK the rail is CHAPS, operated by the Bank of England since November 2017. It has no minimum or maximum payment limit, usually opens at 6am, and customer payments must be submitted by 5.40pm on a working day. It is what solicitors use on completion day and it is why a house purchase has a deadline in the afternoon.
The Cheaper Route That Skips the Wire
The reason all of this is complicated is that the payment is crossing a border. If both ends of the transfer sit inside one account that holds both currencies, the payment into Britain becomes a domestic UK payment and the IBAN, the BIC and the wire fee all stop applying.
Local Details on Both Sides
A multi-currency account gives you real local account details in several countries, including a UK sort code and account number. Money sent to those details arrives as a domestic payment rather than as an international wire, which is what removes the delay and the correspondent deductions rather than merely reducing them.
On cost, Wise publishes its conversion fee as a percentage starting from 0.24% and uses the mid-market rate with no markup added on top, which is the rate you can check on any rate checker. It holds 40 currencies, is free to open and free to hold, and carries no subscription. The full assessment is in our Wise review, and the underlying rate concept in our guide to the mid-market exchange rate.
What It Cannot Do
It is not a bank. Wise Payments Limited is an authorised electronic money institution under the Electronic Money Regulations 2011, so money is safeguarded rather than covered by the Financial Services Compensation Scheme, and Wise states that plainly. There is no overdraft, no lending, no branch and no cash.
It also does not remove the need to get details right. You still have to type the sort code and account number correctly, and a wrong digit is still a wrong digit. What changes is that a domestic payment that fails usually bounces back the same day rather than disappearing into a correspondent chain for a week.
Who This Suits
Anyone paying or being paid across the US and UK regularly: contractors invoicing abroad, people with family on the other side, anyone with a mortgage or rent in one country and income in the other. For a single one off payment the saving is smaller and a bank wire may be simpler.
If you are choosing a UK bank rather than a route, our comparison of what UK banks charge on international transfers prices the receiving side, which is the half that most comparisons ignore.
The Bottom Line
UK bank accounts do not have routing numbers and never will, because the ABA issues them only to US institutions with access to a Federal Reserve master account. The sort code is the equivalent, six digits against nine, and for anything crossing a border you need the IBAN and the BIC instead.
Sending to the UK
Use the IBAN and the BIC, not the sort code, and not a routing number. Check the currency you are sending, because that decides who does the conversion and where the margin lands. If the form has a nine digit routing number field, you are on the domestic page.
Receiving From the US
Give the sender your IBAN and your bank's BIC. Your sort code and account number are already inside the IBAN, so you are not handing over anything extra. And if this happens often, holding local details on both sides removes the international leg entirely, which removes both the delay and the deduction.
Stop Translating Between Two Systems
Sort code against routing number, IBAN against account number, BIC against SWIFT. The simplest way to get all of it right is to not need most of it.
- Local details on both sides: each payment is domestic at the end that matters, so the translation never comes up
- Mid-market rate, published fee: from 0.24%, shown before you confirm rather than hidden in the rate
- Regulated in the UK: an authorised electronic money institution under the Electronic Money Regulations 2011
- Free to open and hold: nothing to lose by having it ready before the next payment
Frequently Asked Questions
Do UK bank accounts have routing numbers?
No. There is no such thing as a UK bank routing number, because a routing number is a US instrument and only a US institution can hold one. The American Bankers Association restricts them to a federal or state chartered financial institution eligible for a master account at a Federal Reserve Bank, which excludes every British bank by definition. What a UK account has instead is a six digit sort code, and that is what the routing number field is asking for even when it does not say so.
What is a bank routing number in the UK?
There is no such thing, and asking what is a bank routing number in the UK is really asking what plays the same role. The answer is the sort code: six digits that identify the bank and the branch, in the same way nine digits identify a US institution. HSBC defines it plainly as a 6 digit number that identifies your bank, and it sits alongside an 8 digit account number.
What is a routing number for a UK bank account?
There is no UK bank routing number to look up, so the nearest equivalent is the sort code, six digits, usually written as three pairs. For an international payment the form will normally want the IBAN and the SWIFT or BIC code instead, and the sort code is already inside the IBAN. So what is a routing number for a UK bank account depends on where the payment is coming from: domestic UK, the sort code; from abroad, the IBAN and BIC.
How many digits is a UK sort code?
Six, and the account number is eight. Together they are the pair that identifies a UK account for any domestic payment. The sort code identifies the bank and the branch, the account number identifies the account within it. HSBC notes the sort code is typically printed on the back of your debit card and also appears on statements, cheques and in online banking.
Is a sort code the same as a SWIFT code?
No, and mixing them up is the most common cause of a rejected payment. A sort code identifies a bank and branch inside the UK domestic system. A SWIFT code, which HSBC says is the same thing as a BIC, identifies the bank internationally so a payment can be routed to the right institution across borders. An international payment usually needs the BIC and the IBAN, not the sort code on its own.
What do I need to send money from a US bank to a UK account?
The recipient's full name, their IBAN and the bank's BIC or SWIFT code. Some forms also ask for the bank name and address. HSBC states that senders generally need the IBAN and BIC or SWIFT code. If the form has a routing number field and will not accept anything else, that form is built for domestic US payments and you are in the wrong place on the website.
What is a UK IBAN made of?
Twenty two characters. Pay.UK sets the structure out as GB, then two check digits, then a four letter bank code taken from the first four characters of the BIC, then the six digit sort code, then the eight digit account number. So the sort code and account number are not replaced by the IBAN, they are carried inside it. Written electronically the spaces are dropped.
What happens if I put a sort code in the routing number field?
Usually the form rejects it, because a routing number field validates for nine digits and a sort code is six. If it does accept it the payment can fail later in the chain and come back days afterwards, minus whatever the intermediary banks took. That is the practical cost of the mismatch, and it is a good reason to use a route that asks for UK details in the first place.
How long does a payment to a UK bank take?
A domestic UK payment is usually near instant on Faster Payments. An international wire typically takes one to five business days depending on the chain. A same day sterling payment inside the UK goes by CHAPS, which the Bank of England operates with no minimum or maximum limit, opening around 6am with customer payments to be submitted by 5.40pm on a working day.
Is there a cheaper way than a wire transfer to the UK?
Usually, and it works by avoiding the international leg entirely. An account that holds both currencies and gives you local details on each side means a payment to Britain arrives as a domestic UK payment rather than as a wire. Wise publishes conversion fees as a percentage, starting from 0.24%, and uses the mid-market rate with no markup added on top.
