Reverse Phone Number Lookup Without Country Code

Question

I have been using googles libphonenumber to perform validation of US phone numbers. Now I am needing international support for all countries. Is it possible to reverse lookup a phone numbers country code using libphonenumber?

Say the DB has saved UK number +448456779463. Is it possible to libphonenumber to detect if that number is UK? It appears I can only check the validity of the number provided I know its country of origin first. But what to do if you have numbers and don't know its country of origin?

allen, did you find a solution for this? – Alexander Suraphel Jun 03 '16 at 15:26 — Alexander Suraphel, Jun 03 '16 at 15:26

Twilio's Lookup tool can likely be of some help here.

It will return a country code based upon number input alone and you can retrieve additional information about a phone via the API.

Twilio lookup is too expensive. – userx Feb 12 '18 at 09:16

You can do it using libphonenumber.

Following is example in python

import phonenumbers
number = "+44XXXXXXXX"
obj = phonenumbers.parse(number)

# get line type
phonenumbers.number_type(obj)

# validate phone
phonenumbers.is_valid_number(obj)

# validate phone for region
phonenumbers.is_valid_number_for_region(obj, "GB")

# get country name
from phonenumbers.geocoder import country_name_for_number
country_name_for_number(obj, "en")

I think following is what you looking exactly,

from phonenumbers.geocoder import region_code_for_number
phonenumbers.is_valid_for_region(obj, region_code_for_number(obj))
