How AlterURL Determines Geo Info for Country-Based Redirects

Today we announced, AlterURL rolled out a major feature: country-specific filtering as part of its redirect criteria. But how exactly does AlterURL determine that geo info in the first place?

Let’s break it down.

The Engine Behind the Geo Detection

At the core of AlterURL’s location-awareness is MaxMind, a leading provider of IP intelligence and fraud detection services. Specifically, AlterURL uses MaxMind’s database to map incoming IP addresses to physical locations — down to the country level (and in some cases, region and city, depending on the license).

Why This Matters

For marketers, product teams, and global campaigns, country-based redirects open up a ton of possibilities:

• Localized promotions

• Country-specific app store links

• Language-targeted landing pages

• Regulatory compliance (e.g., routing users to region-specific disclosures)

And because AlterURL leans on MaxMind’s reliable data, users can trust that their redirect logic is working based on accurate geo information.

Privacy and Compliance

It’s worth noting that AlterURL is designed with privacy in mind. No personally identifiable information (PII) is stored — only anonymized IP-based lookups are used for redirect decisions. This makes it compliant with GDPR and other data privacy regulations.
