Häufige Fragen
Can one regex validate all international phone numbers?
Not reliably. Each country has different formats, lengths, and rules. The E.164 pattern (^\+[1-9]\d{1,14}$) validates the international standard format, but won't check if the number is valid for its specific country. Use libphonenumber for comprehensive validation.
