How to use
- Type or paste the IBAN — spaces are removed automatically.
- The tool checks the length for the country and runs the MOD-97 checksum.
- A green valid result means the IBAN is correctly formed.
Tips
- Compare the IBAN against your bank statement before trusting it.
- A valid checksum proves the format is correct, not that the account exists.
- Pakistani IBANs are 24 characters and start with PK.
- Always confirm account details with your bank before sending money.
Note: A valid checksum does not prove the account exists or belongs to a particular person — always confirm account details with your bank before sending money.
