If you are curious about how to trace a mobile number and retrieve basic details such as location and carrier, Python offers some great tools. In this updated 2025 guide, we’ll walk through a beginner-friendly method using popular Python libraries and a real-world example.

What You’ll Learn

• How to use the phonenumbers library to parse and locate numbers
• Carrier identification
• Adding geopy to enhance location data
• How to validate numbers worldwide

Updated for 2025

With Python 3.12, some improvements in speed and syntax make this process even smoother. This tutorial is fully compatible with Python 3.10 and above.

Prerequisites

pip install phonenumbers geopy

import phonenumbers
from phonenumbers import geocoder, carrier, timezone

# Mobile number (include country code)
number = "+919999999999"

# Parse number
parsed_number = phonenumbers.parse(number)

# Get basic information
print("\n[+] Country:", geocoder.description_for_number(parsed_number, "en"))
print("[+] Carrier:", carrier.name_for_number(parsed_number, "en"))
print("[+] Timezone:", timezone.time_zones_for_number(parsed_number))

# Check validity
print("[+] Valid Number:", phonenumbers.is_valid_number(parsed_number))
print("[+] Possible Number:", phonenumbers.is_possible_number(parsed_number))

Output Example

[+] Country: India
[+] Carrier: Airtel
[+] Timezone: (‘Asia/Kolkata’,)
[+] Valid Number: True
[+] Possible Number: True

Bonus: Add Real Address Info (Optional)

You can use geopy to convert the city name to coordinates:

from geopy.geocoders import Nominatim

geolocator = Nominatim(user_agent="mobile_locator")
location = geolocator.geocode("India")
print("[+] Latitude:", location.latitude)
print("[+] Longitude:", location.longitude)

Final Thoughts

This method provides a quick way to get basic mobile number details for educational or app development purposes. Never use such tools for unethical or unauthorized tracking.
