HLR IPQS fraud detection documentation validation is a service that helps businesses clean up their data lists, removing dead or inactive numbers and improving the effectiveness of their SMS messaging campaigns. By reducing the number of messages sent to invalid numbers, you can save money on messaging costs and ensure your contacts are real and active, leading to better engagement with your business.
A HLR query checks a mobile phone number against the Home Location Register database of a network operator. The HLR stores detailed profiles of mobile subscribers, including their service subscriptions and billing information. When a mobile phone calls or sends a message, the network uses the HLR to verify their identity and confirm service availability. The HLR also updates its database when a mobile handset moves to a new region, by sending a Location Area Index (LAI) to the Mobile Switching Center (MSC).

Using an HLR lookup, you can determine whether a phone number is valid and actively in use in a given country or network. It can also help you identify when a mobile number has been ported to another carrier or if it is currently roaming, which is incredibly useful for optimizing message routing and reducing costs.
