HLR stands for Home Location Register, which is a central database that contains details of each mobile phone subscriber that is registered with a particular mobile network. When you do an HLR lookup, you can find out important info about a particular mobile number.
The HLR or “Home Location Register” is at the core of every GSM mobile network worldwide. The HLR is a central database of all customers authorised to use the network. Every SIM card that is released has a unique number attached to it called an IMSI. This number is basically a primary key associated with the HLR record.
You can use a lookup to see if a number is:
- Currently active in a network.
- The original network a mobile number was assigned to
- Ported from another network and which network it was moved to
- Currently roaming
- If the mobile has been turned on recently and what country the mobile was last used
Why would a business want to do an HLR lookup?
It holds the most accurate, up-to-date information on a mobile subscriber. This could help you to eliminate numbers on your database that doesn’t exist or are invalid so you don’t waste time and money sending messages to these numbers.
Is an HLR lookup difficult to perform?
Nope. It is fast and inexpensive. A lookup can also be performed in real time during call setup or SMS delivery. You should be able to find network carrier information quickly and cheaply and even improve routing for VoIP and SMS traffic.
What about privacy?
These lookups are non-invasive and you perform it remotely. The mobile user won’t see anything on their phone. You also won’t be able to access any info on the user’s phone or somehow gain control of it – it is structured only around the idea of validating phone numbers.
It is a must-have tool for any business who has a mobile database for their communication and marketing purposes.
