## Coverage, stated honestly

Coverage differs by product:

- **US and Canada are our strongest coverage** across the phone
  products, and reverse phone/email/IP lookup and skip tracing are
  **US-focused**.
- **HLR, ported-number, and number-type lookups work internationally**:
  they query live carrier networks. International phone spam/risk
  scoring also exists.
- **DNC/compliance checking is a US product.**

We do not publish country counts or blanket accuracy percentages,
because honest coverage varies by product and country. The reliable way
to know whether 1Lookup fits your country and use case: run a sample of
your own data on a trial. Volume buyer? The team will confirm coverage
