HLR Lookups Explained
Watch our brief explainer video and learn how HLR Lookups query mobile network operators to verify phone number status in real-time.
What is an HLR Lookup?
HLR Lookup is a powerful technology that verifies the status of any GSM mobile number in real time. By querying the Home Location Register (HLR), a lookup determines whether a number is valid, active on a mobile network, and, if so, identifies the associated network. It also detects whether the number has been ported from another network or is currently roaming.
Our Enterprise HLR Lookup Platform and API are built for reliability and scalability, offering redundant access to a global network of SMS centers and multiple geographically distributed connections to the SS7 mobile signaling network.
