How it works

How to use in 3 simple steps

1

3

Get the full profile

See validity, line type, area, carrier, time zone, and formats instantly.

What this tool tells you

Every field, explained

The lookup runs the same open numbering-plan dataset that powers Google's libphonenumber library, entirely in your browser.

Validity & line type

Checks the number against the country's numbering plan and classifies mobile, fixed line, VoIP, toll-free, premium, and other ranges.

Area & carrier

Fixed-line numbers resolve to a city or region; mobile numbers resolve to the operator that originally owns the number range.

Time zone

Maps the number range to IANA time zones, including multi-zone countries like the US, Canada, Russia, and Brazil.

Standard formats

Get E.164, international, national, and RFC 3966 dial formats for CRM imports, messaging APIs, and click-to-call links.

Data source & limits

What range metadata can — and cannot — tell you

What you get

  • • Numbering-plan validity for 240+ countries and regions
  • • Line-type classification across 11 range categories
  • • City or region for geographic (fixed-line) numbers
  • • Original range carrier for mobile numbers
  • • IANA time zones and standard number formats

What it cannot do

  • • Mobile numbers have no city — only the range operator
  • • Carrier reflects the original allocation, not number portability
  • • No live active/disconnected status
  • • No roaming, portability, or risk scoring

Need live answers? The paid app runs real-time HLR-grade checks — active status, current carrier after porting, and risk signals — across whole CSV files or via API.

Best practices

Tips for accurate lookups

A clean input format improves every field the lookup returns.

Use international format

Include the country code whenever possible, such as +14155550198 or +49301234567.

Pick the right country

Shared codes like +1, +7, and +44 span several countries — the tool lists all plausible matches.

Recheck before campaigns

Range metadata is stable, but live status changes — validate lists before each send.

FAQ

Free Phone Number Lookup FAQ

Quick answers about the free phone number metadata lookup.

Is this lookup really free and unlimited?
Yes. The lookup runs entirely in your browser against open numbering-plan data, so there is no per-query limit and no account required.
Where does the data come from?
The same open dataset that powers Google's libphonenumber library: numbering plans, geographic ranges, original carrier allocations, and time zone mappings, refreshed regularly.
Why does a mobile number show no city?
Mobile ranges are not geographic — the number works nationwide. For mobile numbers this tool shows the operator that originally owns the range instead.
Does the carrier result include ported numbers?
No. The carrier field is the original range allocation. For the current carrier after porting and live active status, use the paid bulk validator or API.
Are my numbers stored or sent anywhere?
No. Parsing and matching happen locally in your browser. Nothing you type is transmitted to a server or logged.
How is this different from the Free Phone Validator?
The Free Phone Validator runs a live server-side check with a free usage limit. This lookup page is offline metadata — unlimited, but without live status. Use both: metadata first, live checks before sending.
