Is there a pattern to validate if a phone number is of a concrete country?

I want to know if there is any default pattern to validate if a phone number is of a concrete country?

Currently, I am using a Patterns.PHONE.matcher(phone).matches(); but this validates a phone, no an EEUU phone, Italy phone, etc...

How can do for know if the telephone number is a number of a concrete country? And is it possible to do without the international prefix like +0012?

Solution

  • Use libphonenumber library from Google

    implementation 'io.michaelrocks:libphonenumber-android:8.8.5'

    code

      PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.createInstance(this)
  PhoneNumber phoneNumber = phoneNumberUtil.parse("+917874962727", null)
  String regionCode = phoneNumberUtil.getRegionCodeForNumber(phoneNumber) // IN for India

    getRegionCodeForNumber will give you country code. further, you can map like

    • US => USA
    • IN => India
    • IT => Italy
