Phone Lookup — Identify Any Number Worldwide
Enter any international phone number and instantly learn the carrier, country, line type, geographic region, and whether a Facebook account is linked — all from public data sources.
What Phone Lookup Reveals
Carrier / Operator
The mobile or landline operator that issued this number, even after number portability
Country & Region
Country of origin from the international prefix, plus geographic region for fixed lines
Line Type
Mobile, landline, VoIP, toll-free, or virtual number — flags suspicious disposable numbers
Timezone
Local timezone derived from the number's geographic origin
Number Portability
Detects when a number has been ported to a different carrier
Facebook Check
Checks Facebook's public GraphQL for an account registered to this number
Facebook Account Detection
One of Vestigo's unique capabilities is its Facebook phone number check. Using Facebook's public GraphQL endpoint, Vestigo determines whether a Facebook account is registered to the phone number — and if so, retrieves the public profile link and display name.
This is possible because Facebook allows phone number lookups for account recovery purposes via a publicly accessible (but undocumented) endpoint. No login is required and no private data is accessed.
Number Formats Supported
Vestigo automatically normalizes phone numbers to E.164 format before processing. Accepted input formats include:
+1 (555) 123-4567 · +33 6 12 34 56 78 · 0033612345678 · +49 170 1234567 · 07911 123456 (UK local format)
All major international dialing formats from 200+ countries are recognized automatically.
