SSN regex

This number has the following rules:

  • consists of 9 digits and usually divided by 3 parts by hyphen (XXX-XX-XXXX).
  • The first part can not be 000, 666, or between 900-900.
  • Second part can not be 00
  • Third part can not be 0000

Below is a simple SSN regular expression that is divided by hyphens.

  • If you want to make hyphens optional, put ? after each dash
  • If you want to validate SSN without hyphens - just remove them
/^(?!666|000|9\d{2})\d{3}-(?!00)\d{2}-(?!0{4})\d{4}$/
Test it!
/^(?!666|000|9\d{2})\d{3}-(?!00)\d{2}-(?!0{4})\d{4}$/

True

False

Enter a text in the input above to see the result

Example code in Javascript:

var ssnRegex = /^(?!666|000|9\d{2})\d{3}-(?!00)\d{2}-(?!0{4})\d{4}$/;
// Validate SSN
ssnRegex.test('000-22-3333'); // Returns false
ssnRegex.test('100-22-3333'); // Returns true

// Extract SSN from a string
var ssnRegexG = /(?!666|000|9\d{2})\d{3}-(?!00)\d{2}-(?!0{4})\d{4}/g;
'My SSN is 100-22-3333'.match(ssnRegexG); // returns ['100-22-3333']
