Phone Number Regex Patterns by Country

Phone number formats vary wildly across countries. This guide provides tested regex patterns for the most common formats, plus a universal pattern for international numbers.

Universal: E.164 International Format

The E.164 standard is the safest format for storing phone numbers globally:

^\+[1-9]\d{6,14}$

Format: + followed by country code and subscriber number (7-15 digits total).

Examples: +14155551234, +442071234567, +905551234567

Test these patterns: Open our Regex Tester and paste any pattern to validate it against your phone numbers.

United States & Canada (+1)

^(\+1)?[-.\s]?\(?\d{3}\)?[-.\s]?\d{3}[-.\s]?\d{4}$

Best Practices

Store in E.164 format — Always normalize to +[country][number] for storage and comparison.
Display in local format — Show numbers in the user’s local format for readability.
Use a library for production — Libraries like libphonenumber (Google) handle edge cases that regex cannot. Use regex for quick client-side validation, libraries for server-side.
Accept flexible input — Let users type numbers with spaces, dashes, or parentheses. Normalize during processing.

Flexible Input Cleaner

Before validating, strip formatting characters:

const clean = phone.replace(/[\s\-\(\)\.]/g, '');
// Then validate the cleaned number
