Why PilotLookup
Accurate, fast, developer-friendly.
The data quality of an enterprise provider, priced and packaged for teams that just need the answer.
Built for low latency
Edge-accelerated lookups against an indexed carrier dataset. Fast enough to sit inline in your signup flow, not just in a nightly batch.
Data you can act on
Carrier, line type and location enriched from multiple authoritative sources and ML heuristics, continuously refreshed so routing decisions stay correct.
Pay only for what you use
Buy credits in packs, spend them at your own pace. No seats, no minimums, no multi-year contract, and nothing expires if a quarter goes quiet.
The platform
One request. Every signal.
Each lookup returns the full picture of a number, in clean JSON, from the same endpoint.
Know the carrier behind every number
AT&T, Verizon, T-Mobile, MVNOs and regional operators, resolved from authoritative sources and kept current.
Mobile, landline or VoIP
Route SMS away from landlines, flag VoIP before it burns a verification send, and cut failed deliveries.
City and state, on every lookup
Geographic context on each number, with local and E.164 international formatting returned alongside.
Keys, usage and audit logs
Scoped API keys, per-key usage analytics and exportable logs, all managed from your dashboard.
Customer stories
Trusted by developers around the world.
Thousands of teams rely on PilotLookup every day to validate numbers, reduce fraud and improve deliverability.
