Frequently Asked Questions
Is there a universal phone regex?
No single regex handles all international formats. Start with /^\+?[1-9]\d{1,14}$/ for E.164 format, or build country-specific patterns.
Should I strip formatting before validation?
Yes. Remove spaces, dashes, and parentheses before applying your regex for cleaner matching.
