Build, test, and debug regular expressions
Matches Brazilian phone numbers in flexible formats, optionally capturing the +55 country code, a two-digit area code (DDD) with or without parentheses, and the subscriber number which may start with 9 for mobile lines. Accepts spaces or hyphens as separators between groups (e.g., +55 11 91234-5678, (11) 91234-5678, or 1234-5678). Ideal for validating or extracting landline and mobile numbers from Brazilian user input in forms or text data.
