What is the regex generator?

The regex generator gives you a ready, tested regular expression for the most common patterns – email addresses, URLs, domains, IPv4 and IPv6, Indian mobile numbers, PIN codes, PAN, GSTIN, Aadhaar and IFSC codes, dates, times, colors, UUIDs and more – in JavaScript, PHP and Python syntax.

Choose whether to validate a whole value or to find matches inside a text, and paste test values to see what matches.

Frequently asked questions

Can a regex fully validate an email?

Not completely: the pattern catches typos, but only sending an email proves the address exists.

What do ^ and $ mean?

The start and the end of the value, so the whole value must match.

How do I test my own regex?

Use the regex tester to see every match and group.
