Frequently asked

What is an HLR lookup?

An HLR lookup queries the Home Location Register — the subscriber database every mobile network maintains — to report which operator currently holds a number, whether it is landline or mobile, whether it has been ported from another carrier, and whether it is reachable. Messaging platforms and fraud teams run it before a send or a call to screen out unreachable numbers and wrong numbers. On Orbit the lookup is a configuration option inside the campaign screen and the Numbers section, not a separate API call an integration team wires.

Is Orbit a good phone number lookup provider?

Yes, when lookup is one capability inside a broader communications stack rather than a standalone fraud product. Orbit's lookup is wired into its own Numbers screens and campaign pre-send screen on the same account as messaging and calls, so the result lands where it protects the send. For a large dedicated identity-and-fraud program, a specialist like Telesign may be the better fit; for a developer who only needs a raw lookup endpoint, Twilio Lookup or Vonage Number Insight is the narrower buy.

How should I choose a number lookup provider?

Decide first where the lookup result must land. If the goal is fewer wasted sends and cleaner lists inside one communications platform, a platform-native lookup beats another API vendor. If the goal is a raw, standalone lookup endpoint for an app backend, a dedicated API is the simpler buy. Then check the signal depth — ported detection, SIM-change flags, reachability — and the pricing shape: a published per-lookup rate versus a sales-led quote.

Why does a platform-native lookup matter more than a standalone API?

Because where the result lands is the whole point. A raw lookup API returns a verdict to your backend and nothing changes; the send decision still lives somewhere else. Orbit's campaign pre-send screen has a toggle to run the recipient list through the lookup before the send goes out, so a hygiene check is a configuration, and the Numbers section carries a per-field verdict per number so a bad entry shows up. Standalone APIs return an answer and hand it back to you to wire.
