Phone Number Regular Expressions

Category: Numbers

A collection of useful Regular Expressions to parse, validate, and format phone numbers around the world.

For many of us, knowing how to work with regular expressions is a huge time saver. Regular expressions are powerful but can be easy to misuse or even get wrong.

If you aren’t careful when building regex patterns, you can waste a lot of time tracking down hard-to-find bugs.

That’s why I created this handy collection of regexes that are great for phone numbers.

Conclusion:

If you find that you need to parse, validate, or format phone numbers, the regular expressions found in this post will be a great help.

Just remember that international phone numbers can vary widely, and without context it can be difficult to determine which country codes are used or how to arrange these digits into a specific format.

The best solution for you is likely to check the source of the number to ensure its validity, although these regular expressions can still be useful if no such information is available.
