What is a sort code in the UK?
A sort code is a 6 digit number, written as 12 34 56, that identifies the bank and branch where a UK account is held. Think of it like the postal code for your account, it points the payment to the right institution and location. A standard UK account needs two things, the 6 digit sort code, and the 8 digit account number, without both, payments will not process correctly.
Where sort codes are used
- Faster Payments: near instant bank transfers, typically minutes, often within a couple of hours.
- BACS: a 3 business day credit or debit cycle, common for payroll and supplier payments.
- CHAPS: same day high value transfers, used when same day settlement is required.
These networks form the backbone of UK domestic banking, and all three rely on sort codes to route payments correctly.
Format and examples
The format is always XX XX XX, such as 04 00 04 or 20 45 45. The first two digits usually identify the banking group, the remaining digits narrow down region and branch. On a UK invoice, “Bank details” usually means account name, sort code, and account number. For local GBP transfers, you do not need an IBAN, the sort code and account number are sufficient.
Understanding bank identifiers for cross border payments
A bank identifier is any code that tells the payment system where the account lives, which bank, institution, sometimes branch and country. Different countries built different standards, so you must match the identifier to the client’s banking location.
- Sort code: UK domestic identifier, 6 digits, used with account number for UK GBP transfers.
- Routing number, ABA: US domestic identifier, 9 digits, used for USD ACH and wires inside the United States.
- SWIFT/BIC: global bank identifier, 8 to 11 characters, used for international wires.
- IBAN: international account format, used mainly in Europe, often embeds local identifiers, including sort codes in some countries, see IBAN.
Domestic payments rely on local identifiers, sort codes in the UK, routing numbers in the US, IFSC in India. Cross border payments rely on SWIFT/BIC, and often IBAN in Europe. Match the code to the client’s bank and payment network.
Sort code vs routing code vs SWIFT/BIC vs IBAN: a clear comparison
Side by side comparison
- Sort code: UK, Ireland, 6 digits, for UK domestic GBP transfers through Faster Payments, BACS, CHAPS.
- Routing number, ABA: United States, 9 digits, for USD ACH and wires domestically.
- SWIFT/BIC: global, 8 to 11 characters, for international wires.
- IBAN: mainly Europe, up to 34 characters, for international or SEPA transfers, see routing, sort codes, IBAN.
When to use each identifier
- UK client paying from a UK bank in GBP: give sort code and account number, they will use Faster Payments or BACS.
- US client paying from a US bank in USD: give routing number and US account number, ACH is cheap and familiar.
- Cross border payment, any country: give SWIFT/BIC plus account number, and if EUR or SEPA, also IBAN, see sort codes.
Common confusion checks
- If a UK client asks for a routing number, they usually mean sort code, clarify the UK uses sort codes, not ABA routing.
- If a European client insists on IBAN, share your IBAN, it already encodes local details including the sort code where applicable.
- SWIFT/BIC alone is not enough, you still need your account number, often IBAN too, see bank codes guide.
Quick memory hook: local bank, local code, international wire, SWIFT, sometimes IBAN. Match the client’s country first, the identifier follows naturally.
How and where to find your sort code
- Bank statements: shown with your account number at the top account details section.
- Online or mobile banking: under “Account details,” “GBP account details.”
- Debit cards: some banks print sort code and account number, though this is less common now.
- Virtual GBP accounts with cross border platforms display a sort code and account number inside your dashboard.
Verification tips
Before sharing, verify the digits, use your bank’s official checker where available, or contact support to confirm bank name, sort code, account number. Copy details directly from your app or statement, avoid typing from memory. A single wrong digit can bounce funds or send to the wrong account, see sort code verification.
Payment networks in the UK and why sort codes matter
- Faster Payments: near instant, often minutes, typically within two hours, used for everyday transfers.
- BACS: 3 business day cycle for payroll and regular supplier payments.
- CHAPS: same day high value transfers, banks charge higher fees, see UK transfer networks.
The sort code tells the system how to route, which networks the account supports, and ensures the payment reaches the right institution. This is why the sort code must be exactly correct.
Practical steps for Indian freelancers invoicing UK clients
For a UK based client paying GBP to a UK account, or a UK routed virtual account, include:
- Account name: exactly as registered.
- Sort code: 6 digits, format XX XX XX.
- Account number: 8 digits.
- Currency and amount: GBP, plus invoice amount.
- Optional but recommended: invoice number, due date, and payment reference so reconciliation is easy, see invoice identifiers.
How to avoid payment delays
- Double check every digit, copy and paste from your banking app.
- Ask the client to match the payee name closely to bank records, many banks run automated name checks.
- Specify, “Please pay via UK bank transfer, Faster Payments or BACS,” so they use the right rails.
If your client is not in the UK
- US client to US account: share routing number and account number for local ACH or wires.
- EU or EEA client: share IBAN and SWIFT/BIC for SEPA or cross border transfers.
- Other countries: share SWIFT/BIC plus local account number, and any local code required. For a quick primer, compare sort code vs routing number.
Common mistakes and how to avoid them
Mixing up routing code and sort code
UK equals sort code, 6 digits, US equals routing number, 9 digits. If in doubt, ask which country the client’s bank is in, then provide the matching identifier. For context on the term routing number in the UK, see ABA routing number in the UK.
Using old sort codes after mergers
Banks merge, branches close, systems consolidate, always pull the sort code from current statements or your app.
Confusing building society roll numbers
Some building societies use roll numbers in addition to sort code and account number, follow your provider’s instructions carefully.
Formatting errors
Write sort codes as XX XX XX for clarity, watch for transposed digits, copy and paste rather than typing from memory.
Name mismatch issues
Use your legal or registered business name, not a nickname, UK banks are stricter on name matching now.
Security note
It is safe to share your sort code and account number for receiving payments, these appear on invoices routinely. Never share PIN, CVV, full card numbers, or online banking passwords. For a general overview, see bank sort codes.
India specific realities and tips for freelancers

FAQ
What is the sort code meaning for UK payments if I am an Indian freelancer?
A sort code is the 6 digit UK bank identifier that, together with your 8 digit account number, routes domestic GBP transfers like Faster Payments, BACS, and CHAPS. If your UK client is paying locally, they will ask for sort code and account number, not SWIFT or IBAN.
Do I need IBAN or SWIFT to get paid from a UK client, or is sort code enough?
For local GBP transfers inside the UK, sort code and account number are enough. For international wires into the UK, banks typically require SWIFT/BIC, account number, and sort code together, SWIFT alone is not sufficient.
How can I get UK sort code and account number without a UK residency?
Use a cross border platform that provides virtual GBP account details, for example, Karbon Business can issue a UK sort code and account number in your name, your client pays locally, and you settle to INR with e-FIRA support.
Which is cheaper for my UK client, paying to sort code or doing an international wire to my Indian bank?
Paying to sort code via local transfer is usually cheaper and faster for UK businesses, often free or very low fee, while international wires to India can cost £15 to £40, take multiple days, and require extra compliance forms.
If a UK client asks me for a routing number, what should I share?
Clarify that in the UK the equivalent is the sort code, send your 6 digit sort code and 8 digit account number, if they still insist on routing number, explain that routing numbers are a US only concept.
How do I verify my sort code and account number before putting them on invoices?
Open your bank or fintech app and copy the details from “Account details,” check your PDF statement, or contact support for confirmation. Avoid typing digits from memory, one transposed number can delay funds.
Can I use Karbon Business to receive GBP from multiple UK clients and then convert to INR later?
Yes, you can hold GBP in your Karbon account, then convert to INR when you prefer, with zero FX markup on conversion. This lets you time conversions based on cash flow or market rates.
If my European client asks for IBAN, can I still get paid into my GBP account with sort code?
If they are sending SEPA or EUR, they will expect an IBAN and SWIFT/BIC. If they are in the UK paying in GBP, sort code and account number are fine. Many freelancers keep separate EUR and GBP accounts to match client preferences.
What payment reference should UK clients use so I can reconcile quickly?
Ask them to include your invoice number or your business name, and specify this on the invoice. Clear references speed matching and reduce follow ups when multiple payments arrive on the same day.
Is it safe to share sort code and account number publicly on invoices?
Yes, UK businesses routinely share these details for receiving payments. These cannot be used to withdraw funds. Never share card PIN, CVV, full card numbers, or online banking credentials.
What is the difference between sort code and SWIFT/BIC in simple words?
Sort code is local to the UK for domestic GBP transfers, SWIFT/BIC is global for international wires. Sort code directs payments inside the UK, SWIFT identifies your bank internationally, you still need the account number, often IBAN, to credit your exact account.
How quickly does a UK Faster Payments transfer reach me if I use Karbon Business?
Most Faster Payments arrive within minutes to a couple of hours. After funds reach your GBP account, you can claim and settle INR, typically within 24 to 48 hours, with e-FIRA generated automatically for compliance.
