If you send or receive payments across the UK or Europe, you’ve probably been asked for an IBAN. But what exactly is it, and why is it so important for businesses, especially those operating internationally?
In this guide, we clearly explain what an IBAN is, what the IBAN meaning is, and how it’s used in everyday business payments.
An IBAN (International Bank Account Number) is a standardised number used to identify bank accounts when sending or receiving payments internationally.
In simple terms, an IBAN helps banks make sure that money is sent to the correct account, especially when payments cross borders.
👉 So, if you’re asking “what is an IBAN?” — it’s a safer and more accurate way to share bank details for international transfers.
The IBAN meaning is straightforward:
IBAN = a globally recognised bank account format that reduces payment errors and speeds up international transfers.
It was introduced to:
Improve payment accuracy
Reduce delays and failed transactions
Make international banking easier and more secure
IBANs are mainly used across Europe, the UK, and many other international markets.
An IBAN can be up to 34 characters long and includes:
Country code (e.g. GB for the UK)
Check digits (used to validate the number)
Bank and account details
This format helps banks automatically verify and process payments correctly.
IBANs are used to:
✔ Send international bank transfers
✔ Receive payments from overseas customers
✔ Process SEPA and cross-border payments
✔ Reduce failed or misdirected transfers
✔ Speed up settlement times
For businesses operating in the UK and Europe, IBANs are essential for smooth financial operations.
Yes — UK businesses still use IBANs.
Even after Brexit:
IBANs remain the standard for international payments
SEPA transfers still rely on IBAN details
European partners continue to request IBANs
If you trade with Europe or receive payments internationally, you will need an IBAN.
| Detail | Used In |
|---|---|
| Sort Code & Account Number | UK domestic payments |
| IBAN | International & European payments |
| SWIFT/BIC | Identifies the bank itself |
IBANs combine multiple identifiers into one internationally accepted format.
You’ll usually need an IBAN if you are:
A UK business trading with Europe
An eCommerce store accepting international payments
A company using SEPA transfers
A high-risk or cross-border merchant
A business using multi-currency or offshore accounts
Many modern business accounts and payment providers now issue dedicated IBANs for easier global payments.
Most businesses receive an IBAN automatically when opening:
A European bank account
A multi-currency business account
An EMI or payment institution account
