Example of a regular expression for phone numbers

Question

I'm very new to javascript, I just want a reqular expression for validating phone numbers for one of my text field.

I can accept -+ () 0-9 from users, do you have regex for this one or a regex for phone numbers better then the one i need?

Thanks in advance.

Use this rexeg

/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/

(123) 456 7899
(123).456.7899
(123)-456-7899
123-456-7899
123 456 7899
1234567899

Yes that is the regex but my comment is that there are so many possible splits of numbers and people don't always use the official ones - it is better just to accept numbers and forget the pattern – mmmmmm Aug 06 '11 at 10:06
@Mark: aah. Yes... It's better – genesis Aug 06 '11 at 10:28
This seems to be US only, no support for international numbers – Arne Burmeister Jul 30 '21 at 07:40

Try this

function validatePhone(phoneNumber){
   var phoneNumberPattern = /^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$/;  
   return phoneNumberPattern.test(phoneNumber); 
}

For Italian Phone number:

/^([+]39)?((3[\d]{2})([ ,\-,\/]){0,1}([\d, ]{6,9}))|(((0[\d]{1,4}))([ ,\-,\/]){0,1}([\d, ]{5,10}))$/

+39 347 12 34 567
347-1234567
347/1234567
347 123456
3471234567
02/1234567
051 12 34 567

For global users have a look into this library libphonenumber-js.

this will let you validate global mobile numbers.

For U.S. phone numbers:

/(((\(\d{3}\) ?)|(\d{3}-)|(\d{3}\.))?\d{3}(-|\.)\d{4})/g;

For U.S. hrefs with phone numbers:

/((\"tel:((\d{11})|(\d{10})|(((\(\d{3}\) ?)|(\d{3}-)|(\d{3}\.))?\d{3}(-|\.)\d{4}))\"))/g;

I know these are a bit clunky but they will catch most of the improperly formatted phone numbers you see around the internet.

Wanna see how it works in jquery? Check out: https://jsfiddle.net/uohx1fo3/15/

This regex works pretty widely for phone numbers:

^(\+)?(\d{1,2})?[( .-]*(\d{3})[) .-]*(\d{3,4})[ .-]?(\d{4})$
