Send a lookup

POST to /v2 with your checks array, or use the portal.

checks: ["Auto","Hlr","Tps"]
02

We validate it

HLR · MNP · landline · TPS/CTPS · email - live.

// live network query
03

Get a verdict

Live, ported, on TPS - with a free syntax fallback.

{ valid: true, hlr:{ on:true } }

Choose Data Soap if you want HLR plus suppression, email and address validation in one UK-based platform - not just raw mobile lookups.

Read the comparison HLR lookup

Data Soap vs HLR Lookup

Read the comparison SMS & validation
