Regex Tester & Validator

Matches El Salvador phone numbers (both landline and mobile) in flexible formats. It optionally captures a 3-digit area/country code (e.g., 503), which may be wrapped in parentheses, then captures two blocks of 4 digits each. Any non-digit characters such as spaces, dashes, or dots are allowed between the number groups, making it robust for parsing numbers like (503) 2222-3333 or 7123-4567.
