Regex Tester & Validator

This regular expression matches a 5-digit numerical string, effectively enforcing a range from 00000 to 52999. It validates that the first two digits fall between 00 and 52 using a combination of alternatives (00-49, 50-52, or 01-09), followed by exactly three digits. This pattern is typically used for validating specific postal codes where the numerical range is restricted to designated regional prefixes.
