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We do not publish country counts or blanket accuracy percentages,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
