HLR lookup ยท coming soon
HLR Lookup API
An HLR (Home Location Register) lookup asks the mobile network about a number: whether it is active, which operator serves it after porting, and whether it is roaming. It tells you what a numbering-plan check cannot: if a valid mobile number can actually receive calls and SMS right now.
HLR lookup is coming soon
Live network lookups are in development. Contact us for early access. Today, /v1/validate returns the carrier and line type from numbering and carrier data, without a network query.
What an HLR lookup tells you
- Network status
- Whether the number is active (connected) or absent on the network.
- Current operator
- The operator that serves the number now, after any porting.
- Ported
- Whether the number was moved from its original operator.
- Roaming
- Whether the subscriber is currently on a network abroad.

Send only to numbers that are live, and route by the current operator after porting.
Fraud and account security
Check that a number used for one-time codes is active before you rely on it.
List hygiene
Remove disconnected mobile numbers from campaigns and CRMs.

Pricing for HLR lookups will be published at launch. Until then, validate numbers and look up carrier and line type on the free plan (100 requests a month).
