Iceland IBAN Regex Pattern

^IS\d{2}\d{4}\d{2}\d{6}\d{10}$

Pattern validates length, country code, check digit positions, and field character types. Does not verify the MOD-97 checksum (use the validator above for full validation).

PHP

$iban = strtoupper(str_replace(' ', '', $input));
if (!preg_match('/^IS\\d{2}\\d{4}\\d{2}\\d{6}\\d{10}$/', $iban)) {
    // Invalid Iceland IBAN format
}

JavaScript

const iban = input.replace(/\s+/g, '').toUpperCase();
const pattern = /^IS\d{2}\d{4}\d{2}\d{6}\d{10}$/;
if (!pattern.test(iban)) {
  // Invalid Iceland IBAN format
}

Python

import re
iban = input_str.replace(' ', '').upper()
pattern = r'^IS\d{2}\d{4}\d{2}\d{6}\d{10}$'
if not re.fullmatch(pattern, iban):
    # Invalid Iceland IBAN format

These snippets check format only. For full IBAN validation including MOD-97 checksum, use a dedicated IBAN library or the validator on this page.

How to Find Your Iceland IBAN

Iceland accounts are traditionally identified using: Bank Code (4n) + Account Type (2n) + Account Number (6n) + Check Digits (2n) + Kennitala / ID Number (10n). Your IBAN encodes these same components in the standardised international format.

1
Mobile banking app — Open your bank's app, navigate to account details or "Account Info." Your IBAN is usually displayed alongside your account number. Look for a field labelled "IBAN" or "International Account Number."
2
Bank statement — Your Iceland IBAN appears in the account header of your printed or PDF bank statement, typically near the top of the first page.
3
Online banking — Log in to your bank's website and go to "Account Details," "Account Summary," or "Profile." Most Iceland banks display the IBAN prominently in account settings.
4
Bank branch or helpline — Call your bank's customer service or visit a branch with your ID. They can provide your full IBAN instantly.

Once you have your IBAN, use the validator above to confirm it is correctly formatted before sharing it.
