About this tool

What you provide

  • An IBAN pasted in any shape — spaces, an «IBAN:» prefix and Arabic digits are all accepted
  • Or, to build one, a Saudi, Kuwaiti, Bahraini or Omani bank and the account number as your bank shows it

What you get

  • A valid-or-not verdict with the reason, and the IBAN split into country, check digits, bank and account
  • The identified bank when the bank code is in our sourced list (Saudi Arabia and five Gulf countries)
  • A built Saudi, Kuwaiti, Bahraini or Omani IBAN, copyable grouped or compact, and as a QR code

Limits

  • A valid format does not confirm the account exists — only the bank can.
  • A generated IBAN is built from your own inputs; confirm it with your bank before sharing it.
  • Every country in the SWIFT IBAN registry is checked for length, structure and checksum; Morocco, which is not in it, only for length and checksum.
  • The IBAN is checked on your device and is never sent anywhere.

How to use it

  1. Pick a tab

    Choose Validate to check an IBAN, Generate to build one, or Decode to break one into its parts.

  2. Paste the IBAN

    In Validate, type the IBAN or tap "Paste" — the verdict updates as you type, and when the bank code is in our sourced list the bank is named.

  3. Or build one

    In Generate, pick a country chip and your bank, then enter all the characters of the account as your bank shows them; the check digits resolve once the account is complete.

  4. Copy the result

    On a valid IBAN use "Copy (grouped)" or "QR" to save it as a PNG; Generate adds "Copy compact", and in Decode each segment row has its own copy button.

Frequently asked questions

How can I check if a Saudi or GCC IBAN is valid?

Paste the IBAN into the IBAN tools page and it validates the format and checksum instantly. The check runs on your device, so nothing is uploaded.

Can I build an IBAN from a bank and account number?

Yes. The tool can build IBANs for Saudi Arabia, Kuwait, Bahrain and Oman from your bank and account details. It can't build them for the UAE or Qatar, because the account-number format inside their IBANs isn't consistent across banks. It can also decode an existing IBAN from any SWIFT-registry country to show its parts.

Is the IBAN validator free to use?

Yes, it's free to use with no signup.
