Rule n° 123 - The international dialling codes are available for all phone numbers.

If your target is international, this rule will seem relevant to you from the outset. If it is not, you may doubt it, yet on the Web, a phone number can be searched and dialled from anywhere in the world.

  • Enable the immediate use of telephone contacts, regardless of the user’s environment.


Add the country code to each telephone number in the form +international code - telephone number.

Remove the first 0 for each number. Example for France: +33 1 23 45 67 89.


For each telephone number shown on the site:

  • Check that all numbers are preceded by the country code in the form +international code - telephone number, for example +33 for France.
  • Check that the first 0 of the numbers has been removed. Example for France: +33 6 11 22 33 44.
