Gibraltar IBAN Regex Pattern

^GI\d{2}[A-Z]{4}[A-Z0-9]{15}$

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(' ', '', $input));
if (!preg_match('/^GI\\d{2}[A-Z]{4}[A-Z0-9]{15}$/', $iban)) {
    // Invalid Gibraltar IBAN format
}

JavaScript

const iban = input.replace(/\s+/g, '').toUpperCase();
const pattern = /^GI\d{2}[A-Z]{4}[A-Z0-9]{15}$/;
if (!pattern.test(iban)) {
  // Invalid Gibraltar IBAN format
}

Python

import re
iban = input_str.replace(' ', '').upper()
pattern = r'^GI\d{2}[A-Z]{4}[A-Z0-9]{15}$'
if not re.fullmatch(pattern, iban):
    # Invalid Gibraltar 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.
