Phone Number Regex Example

Match normalized phone numbers with optional plus prefix and 7 to 15 digits.

This phone regex example is designed for normalized phone strings where formatting characters have already been removed. It accepts an optional leading plus sign and then requires 7 to 15 digits, which covers many international phone length ranges. This approach is useful when your UI strips spaces, parentheses, and dashes before validation, or when an API expects E.164-like numeric input. It is intentionally simple so you can use it consistently across frontend forms, import pipelines, and API sanity checks. If your product needs locale-specific formatting rules, extension support, or strict country validation, pair this regex with specialized phone parsing logic. Use the Regex Tester to check both accepted and rejected samples, and add additional constraints once you know your exact input normalization flow.
