NatWest uses branch-specific sort codes — meaning there is no single sort code that applies to all NatWest accounts. Your sort code was assigned when your account was opened and is linked to the branch at that time. Here’s where to find all your NatWest account details and what each one is used for.
NatWest Account Details at a Glance
| Detail | Information |
|---|---|
| Sort code | 6 digits, branch-specific — find in app or online banking |
| Account number | 8 digits — unique to your account |
| SWIFT/BIC code | NWBKGB2L |
| IBAN format | GB + 2 check digits + NWBK + sort code + account number |
| Bank name (for transfers) | National Westminster Bank Plc |
How to Find Your NatWest Sort Code and Account Number
The quickest way is through the NatWest app:
- Open the app and sign in
- Tap on your current account
- Tap Account details
- Your sort code and 8-digit account number are displayed — tap to copy either one
Other ways to find your sort code:
- Online banking — log in at natwest.com, go to your account, and select Account details
- Bank statement — your sort code and account number appear at the top of every NatWest statement
- Paying-in book — if you have a chequebook or paying-in book, the sort code is pre-printed on every slip
- Call NatWest — 03457 888 444 (you’ll need to pass security questions)
What Is a Sort Code Used For?
Your sort code is a 6-digit number that identifies both NatWest as the bank and the specific branch that holds your account. It is used alongside your account number for:
- Receiving UK bank transfers (Faster Payments and BACS)
- Setting up direct debits — employers and service providers need your sort code and account number
- Setting up standing orders from other banks to your NatWest account
- Completing HMRC forms — for tax refunds or self-assessment repayments paid directly to your bank
Sort codes are not secret — it is safe to give your sort code and account number to employers, HMRC, and anyone who needs to pay you money.
NatWest SWIFT/BIC Code
The SWIFT/BIC code for NatWest is NWBKGB2L.
You’ll need this when:
- Receiving an international bank transfer from abroad — give senders your SWIFT/BIC alongside your IBAN
- Making an international payment — though NatWest may handle this automatically when you enter recipient details
SWIFT/BIC codes are publicly listed and safe to share with anyone sending you money internationally.
NatWest IBAN
An IBAN (International Bank Account Number) is used for receiving international transfers into a UK bank account. NatWest IBANs follow the standard UK format:
GB + 2 check digits + NWBK + your 6-digit sort code + your 8-digit account number
Example format: GB29 NWBK 6016 1331 9268 19
Your full IBAN is available in the NatWest app under Account details, or through online banking. Always use the IBAN provided by the app rather than manually constructing one — errors in the check digits can cause transfers to fail or be misdirected.
Sharing Your Sort Code Safely
Your sort code and account number are needed by anyone paying money into your account — they cannot be used to take money out without your authority (that requires your card details, PIN, or online banking credentials). It is safe to share them with:
- Employers (for payroll)
- HMRC
- Government departments (benefits, tax refunds)
- Friends and family sending you money
- Businesses you’re selling to
What to keep private: your card number, CVV, PIN, and online banking passwords. These are what fraudsters need to access your funds.
Storing NatWest Account Details Safely
Your sort code and account number are not secret — you share them with anyone who needs to pay you. However, you should never share your:
- Full card number, expiry, and CVV
- Online banking password or passcode
- One-time passcodes (OTPs) sent by NatWest
Fraudsters sometimes call pretending to be NatWest and ask for security information. NatWest will never ask for your full PIN, password, or one-time passcode. If you receive such a call, hang up and call 159 (the UK banking fraud hotline) to verify.
