HLR Lookup Questions
What is the difference between HLR and MNP lookups?
An MNP (Mobile Number Portability) lookup only tells you if a number has been ported from its original carrier. An HLR lookup is much more powerful; it includes MNP data but also confirms if the number is active, its country, roaming status, and other critical network-level details.
Is performing an HLR Lookup legal and safe?
Yes, absolutely. HLR lookups are a standard telecommunications function used for network routing. The process is secure and does not retrieve any personal subscriber information (like name or address), nor does it alert the user of the phone number. It is an anonymous network ping.
How up-to-date is the information?
The data is provided in real-time. The moment you make a request, our system queries the carrier's HLR database live. The information you receive is the most current data available on the global mobile network at that exact second.
Can I check numbers in bulk or via an API?
Yes. Our platform is built for both. You can upload a contact list file directly to our web dashboard for a one-time cleaning, or you can integrate our simple REST API into your applications to perform HLR lookups programmatically for real-time verification.
