Phone Lookup

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.

What does a phone lookup reveal?
Carrier/operator, country of origin, line type (mobile, landline, VoIP), geographic region, timezone, and whether a Facebook account is registered to that number.

All standard international formats are accepted: +1, +33, +44, +49, and all other country codes. Numbers are normalized automatically to E.164 format before processing.
