Our free lookup tool identifies the caller name and operator when available. It does not expose private information such as addresses or national IDs — our goal is to help you quickly decide whether to answer or return an unknown call.
Developer API
The browser tool signs every Argentina lookup request automatically with a short-lived token and anti-replay signature. For direct integrations, first call /api/client-token, then send the token, timestamp, fingerprint and signature with your lookup request.
GET /api/lookup-international?dialCode=54&countryIso=AR&number=91123456789&token=...&ts=...&fp=...&sig=...You can also use an E.164 number when building server tools, but shared country codes like +1 should include countryIso to avoid United States/Canada ambiguity.
