How to use: IBAN validator
- Paste or type the IBAN, with or without spaces.
- If valid you see the spaced format, the country and the check digits; if not, the reason.
- Copy the formatted IBAN.
What it accepts and what you get
- Input
- An IBAN of up to 34 characters, upper or lower case, with or without spaces.
- Output
- If the IBAN is valid, its grouped format and parts. For Spanish IBANs, also bank, branch, account and the national DC check.
- Where your data is processed
- Your data is processed in your browser and is not sent to our servers.
Limitations and notes
- It checks the country length and the mathematical check (modulo 97). For countries not in the table only the mathematical check is done.
- A valid IBAN does not prove the account exists or who owns it.
- It is validated in your browser; nothing is sent or stored.
Frequently asked questions
Why does it say the check digits do not add up?
Almost always a digit was mistyped or swapped.
Does it work for other countries?
Yes, for those in the length table (many European and other countries). For the rest only the mathematical check is done.
When to use it
- Before sending a transfer, to catch a typo.
- When importing a list of accounts.
- To format an IBAN with spaces.
