HLR – what is it?<\/h2>\n\n\n\n

The Home Location Register lookup<\/a>, or HLR in short, is a database containing information about mobile network subscribers. It contains all numbers and additional information about them, e.g. whether the number has been transferred to another network.<\/p>\n\n\n\n

The HLR lookup is one of the services available to all SMSAPI customers. It allows you to validate your mobile subscriber data<\/strong>. Checking a phone number is easy: access the SMSAPI Customer Panel<\/a>, go to the Additional functions menu and select Check number \u2013 HLR<\/a>.<\/p>\n\n\n\n

How does HLR phone number lookup work?<\/h2>\n\n\n\n

After sending a request from the SMSAPI Customer Panel, the system compares the IMSI number stored in the Home Location Register (HLR) with that assigned to the SIM card. This allows for quick and reliable identification of the subscriber of the cellular network.<\/p>\n\n\n\n

You can check which network a number is registered to or upload a file with the entire database. Whether you test the numbers individually or all at once, the Check number \u2013 HLR page will provide <\/strong>complete information about your subscriber information validity.<\/p>\n\n\n
