What is HLR lookup?
A query against the carrier's Home Location Register to check a mobile number's live status.
An HLR (Home Location Register) lookup queries the database mobile carriers use to track their subscribers. It can reveal whether a mobile number is currently active, which network it's on, and whether it's been ported to another carrier — without placing a call or sending a text.
HLR data makes phone validation more accurate for mobile numbers, helping you avoid dialing or texting numbers that are disconnected or out of service.
