Formatting phone numbers

Basics

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

Here’s the same phone number in E.164 formatting: +14155552671

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

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". You should use a format that someone of the number's country would usually use to share the phone number online.

For example, French people usually write numbers that way online : 06.20.30.40.50 or 06 20 30 40 50.

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

Examples

Here are some examples of custom formatting for US-based phone numbers :

  • +1 618-555-xxxx
  • (+1)618-555-xxxx
  • +1/618-555-xxxx
  • (618) 555xxxx
  • (618) 555-xxxx
  • (618) 555.xxxx
  • (618)555xxxx
  • (618)555-xxxx
  • (618)555.xxxx

For European countries (France as example) :

  • +3301 86 48 xx xx
  • +33018648xxxx
  • +33018 648 xxx x
  • (0033)018648xxxx
  • (+33)018 648 xxx x
  • +33/018648xxxx
  • (0033)018 648 xxx x
  • +33018-648-xxx-x
  • (+33)018648xxxx
  • (+33)01 86 48 xx xx
  • +33/018-648-xxx-x
  • +33/01-86-48-xx-xx
  • +3301-86-48-xx-xx
  • (0033)01 86 48 xx xx
