Regex Editor & Tester

Validates 10-digit phone numbers with optional international country code. Matches formats like 1234567890, 123-456-7890, (123) 456-7890, and +1 123-456-7890, with optional parentheses around the area code and optional hyphen/space separators. The country code portion accepts a plus sign followed by 1-3 digits. Commonly used in form validation and contact data parsing, though it lacks an end anchor so it matches numbers followed by trailing text.
