Overview

IP 2 Country is a free, no-auth API that maps any IPv4 address to its corresponding country. It is useful for basic geolocation features like redirecting users or showing region-specific content. Just pass an IP address as a query parameter to get the country code back.

💡

Beginner Tip

This API only returns country-level data, not city or region. For more detailed IP geolocation, consider ipinfo.io or ip-api.com. It works well as a lightweight first step for country detection in backend scripts.

Common Errors & Troubleshooting

Empty or null country response The IP address is a private, reserved, or loopback address like 127.0.0.1.
✓ Only pass public IPv4 addresses. Test with a real external IP like 8.8.8.8 first.
400 Bad Request The IP address format is invalid.
✓ Ensure the IP is a valid IPv4 format (e.g. 203.0.113.45) without extra characters or spaces.
Unknown country code Some IPs are not mapped in the database.
✓ Handle missing or null results gracefully in your code with a fallback value.
