Regex Editor & Tester

Matches US phone numbers in the format (555) 123-4567. It requires a three-digit area code enclosed in literal parentheses, a single whitespace character, followed by a three-digit exchange code, a hyphen, and a four-digit line number. Useful for form input validation where this specific punctuation style is enforced, though it won't match alternate formats like 555-123-4567 or 555.123.4567.
