What is node-phone?

node-phone is used to normalize the mobile phone number into a E.164 format.

The common problem is user normally input the phone number in this way:

`(817) 569-8900` or
`817569-8900` or
`1(817) 569-8900` or
`+1(817) 569-8900` or ...

What we want is always:



  1. Does node-phone do any phone validation?

    Yes: If you provide the 2nd parameter (country), and the phone number do not start with + sign.

    phone will validate phone_number_lengths and validation_begin_with

    No: If the phone number start with + sign, even you pass the country.

    phone will simply remove all non digit and return +XXXXXXXX to you.

  2. Why some of the number is valid, but return null? This npm is used to validate a mobile phone number for sending the SMS. So, we try to match all possible rule, such as area code, number prefix, etc. to test if it is a mobile phone number. However, some countries, like USA, we can only check if it is a valid AREA CODE, there is no mobile phone prefix.

    For UK, we know that mobile phone number is always start with 7, in this case, this npm will be more helpful.

  3. Why do you make this?

    Because we need to normalize the phone number for SMS notification for mobile phone only.

We don't validate if the number is mobile or not.


npm install phone


var phone = require('phone');

phone('(817) 569-8900', ''); // return +18175698900
phone('(817) 569-8900', 'USA'); // return +18175698900
phone('(817) 569-8900', 'HKG'); // return null
phone('+1(817) 569-8900', HKG); // return +18175698900
phone('(817) 569-8900', ''); // return +18175698900
phone('6123-6123', ''); // return null, as default country is USA
phone('6123-6123', 'HKG'); // return +85261236123


``` npm test



We try to google for many results, but none of package can fit our need. If you know that our rule is wrong, or can add more validation to make this npm more accurate. Please open an issue and let us know.
