Number lookup

Know the network behind a number. Look up its carrier, country and line type, with available mobile network and portability information.

Enter a local number or include + and the country calling code. An international number takes priority over the selected country.

Enter a phone number to see its network information here.

Information varies by country and number. Validity does not confirm that a number is active or can receive verification codes. Network information does not identify the resale supply chain.

NUMBER INTELLIGENCE

What a number can tell you

One lookup. A clearer picture of the network behind a number. Available fields vary by country and number.

  • Carrier name

    Identify the reported network operator and use it as a starting point for checking a number’s network affiliation.

  • Line type

    Distinguish mobile, landline and VoIP numbers when line classification is available.

  • Country

    Get the country code and a normalized international number, ready for your next workflow.

  • MCC & MNC

    Read the mobile country and network codes, when available, to help identify the mobile network.

  • Number validity

    Check reported number validity. This does not confirm that a number is active or can receive a verification code.

  • Portability information

    See porting status and date when returned. Missing data is shown as unknown, never as proof that a number has not been ported.

USE CASES

A little context before your next step

  • Check network affiliation

    Look up a number before investigating its source, with carrier and network codes in one place.

  • Review contact data

    Normalize a number and check its country and reported validity before using it in a workflow.

  • Understand the line

    Use mobile, landline or VoIP classification to inform your next verification step.

  • Investigate delivery issues

    Add network context to your investigation. Message delivery and reachability still need separate checks.

KNOW THE DIFFERENCE

Network identity. Clear boundaries.

What this lookup reveals

The reported carrier, line type, country and available network identifiers. These are clues about the communications network serving a number.

What still needs investigation

Who bought or resold the number, which wholesaler supplied it, and the relationship between intermediaries. Network ownership alone does not reveal a supply chain.

QUERY EXAMPLE

A simple request. Structured results.

This site’s lookup request and an illustrative response. Run a lookup above for live data. This is a demo endpoint, not a production integration contract.

JavaScript

const response = await fetch('/api/number-lookup', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    phoneNumber: '+447700900123',
    countryCode: 'GB'
  })
});

const result = await response.json();
if (!response.ok) throw new Error(result.error.code);
console.log(result.data);

FAQ

You can submit numbers with an international country code. Coverage and available fields depend on the country and number; a successful query may still return only part of the information.
