Oman IBAN validator
How the IBAN format works
- Format
- OM + 2 check digits + 3-digit bank code + 16-char account number (23 chars)
- Example
- OM920180000001299123355
Things to watch for
- 23 characters total
- Checks structure and checksum only, not that the account exists
^OM[0-9]{2}[0-9]{3}[A-Z0-9]{16}$An Omani IBAN is 23 characters: “OM”, two check digits, a 3-digit bank code, and a 16-character account number that can mix letters and digits. That alphanumeric account block sets Oman apart from several of its Gulf neighbors — the UAE’s and Saudi Arabia’s IBANs are both entirely numeric after the check digits, while Oman’s format leaves room for letters within the account identifier itself. The Omani rial, issued through the Central Bank of Oman, is also one of the handful of currencies worldwide subdivided into 1,000 rather than 100 subunits, making it one of the highest-valued currency units in daily use — a detail that has nothing to do with the IBAN’s structure but says something about the banking environment Omani account numbers sit inside. Anyone paying into or receiving funds from an Omani account needs the full 23-character string exactly as issued.
How this validator works
This tool checks the “OM” prefix, confirms the bank code is exactly 3 digits, and confirms the account number is exactly 16 alphanumeric characters, then runs the mod-97 checksum (ISO 7064) a correctly generated Omani IBAN must satisfy — entirely in your browser, with nothing sent to a server.
What a pass doesn’t tell you
A pass confirms the 23 characters are correctly structured and internally consistent — not that the account is open, active, or belongs to whoever you expect. This tool does no lookup against the Central Bank of Oman or any commercial bank there. If an Omani IBAN fails, check the 16-character account block for a letter mistaken for a similar-looking digit — a common source of errors in alphanumeric blocks this long.
Scope: Omani IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Use it to catch a typo before a transfer fails.

IBAN FAQ
What does an Omani IBAN look like?
23 characters: 'OM', two check digits, a 3-digit bank code, and a 16-character alphanumeric account number — for example OM920180000001299123355.
Is an Omani IBAN entirely numeric, like the UAE's or Saudi Arabia's?
No. Oman's 16-character account block can include letters as well as digits, unlike the UAE and Saudi Arabia, whose IBANs are entirely numeric after the two check digits.
Does a passing check confirm the Omani account is real?
No. It only confirms the 23 characters are correctly structured and pass the mod-97 checksum, entirely client-side, with no lookup against the Central Bank of Oman or any commercial bank.
