With a given country and phone number, validate and format the MOBILE phone number to E.164 standard

Phone ·

What is phone?

phone is used to normalize mobile phone numbers into E.164 format.

A common problem is that users normally input phone numbers in this way:

`[phone]` or
`817569-8900` or
`1(817) 569-8900` or
`[phone]` or ...

We always want:

[phone]

Install

npm install phone

Usage

const phone  = require('phone');

phone('[phone]'); // return ['[phone]', 'HKG']
phone('[phone]'); // return ['[phone], 'USA']
phone('[phone]', ''); // return ['[phone], 'USA']
phone('[phone]', 'USA'); // return ['[phone]', 'USA']
phone('[phone]', 'HKG'); // return []
phone('[phone]', 'HKG'); // return [], as it is not a valid HKG mobile phone number
phone('[phone]', ''); // return ['[phone]', 'USA']
phone('[phone]', ''); // return ['[phone]', 'USA']
phone('6123-6123', ''); // return [], as default country is USA
phone('6123-6123', 'HKG'); // return ['[phone]', 'HKG']

Test

npm test

Build

yarn build

Old browsers & browser support

We currently transpile script to work on target environments for which the browser's global usage is >1%, and Node.js 6.10+.

You can check browser usage statistics on the browserlist.

You may need polyfills for some older browsers; for more details, please read the example/README file.

FAQ

1. Does phone do any logical validation?

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

   phone will validate phone_number_lengths and mobile_begin_with

2. Why is phone returning null for a valid phone number?

   This package is used to validate a mobile phone number for sending the SMS.

   Therefore, we try to match all possible rules for specifically checking whether a number is mobile, such as area code, number prefix, etc.

   However, some countries, like the USA, don't have mobile identifiers, so we can only check if the input has a valid area code.

   For example, we know that UK mobile phone numbers always start with 7. In this case, phone can verify that the number is actually mobile.

Help

We've tried to make sure that this package works for as many cases as possible, if you notice that we have an incorrect rule for a country or other case, please open an issue to let us know.
