HLR Lookup
An HLR lookup checks the mobile network's Home Location Register to confirm a number is active before you spend time calling or texting it. Use it on numbers you're authorised to contact.
For verifying and reaching business contacts you're authorised to contact. Not for tracking, monitoring or identifying private individuals. See our Acceptable Use Policy.

Frequently asked
What is an HLR lookup?
The Home Location Register is the network's record of which numbers are active. An HLR lookup confirms a number is live and which network holds it — so you don't waste outreach on dead lines.
How is it different from format validation?
Format validation only checks the number is well-formed. An HLR lookup confirms it's actually active on a network right now.
Does this reveal someone's location?
No. It returns reachability and network status to keep your outreach efficient — it does not provide a person's location, identity or movements, and is only for numbers you're authorised to contact.
Can I check a whole list at once?
This free tool checks one at a time. To verify a full list — email, phone and company together — upload a CSV to BounceBlock and preview your first 100 rows free.
