How to look up a mobile or landline number:

The tool only accepts E164 and International formats as input.

  • E164: +3396360XXXX
  • International: +33 9 63 60 XX XX
  • National: 09 63 60 XX XX
  • RFC3966: tel:+33-9-63-60-XX-XX
  • Out-of-country format from US: 011 33 9 63 60 XX XX

E.164 formatting for phone numbers entails the following:

  • A + (plus) sign
  • International Country Calling code
  • Local Area code
  • Local Phone number

For example, here's a US-based number in standard local formatting: (415) 555-2671

how to lookup number

In the UK, and many other countries internationally, local dialing may require the addition of a '0' in front of the subscriber number. With E.164 formatting, this '0' must usually be removed.

For example, here's a UK-based number in standard local formatting: 020 7183 8750

Here's the same phone number in E.164 formatting: +442071838750

Custom formatting for mobile and landline (home or office) numbers:

Sometimes the phone number has footprints but is used with a different formatting. This is a problem because for example if we search for "+15417543010", we'll not find web pages that write it that way : "(541) 754-3010". So the tool use a (optional) custom formatting given by the user to find further and more accurate results. To use this feature properly and make the results more valuable, try to use a format that someone of the number' country would usually use to share the phone number online.

For example, French people usually write numbers that way online : or 06 20 30 40 50.

For US-based numbers, the most common format is : 543-456-1234.
