International number types

There are several types of phone numbers and many ways to format those numbers depending on where in the world you are placing a call. In some countries, mobile numbers and local numbers are treated differently and you may be charged separate rates based on which one you are calling. This article will explain the formatting of international numbers and the way that CallRail handles those numbers as part of our international call features. Copy

Number formatting

The international standard for phone numbers is known as E.164 number formatting. This system includes all of the required information to route calls and text messages around the world.

E.164 numbers have a maximum of 15 digits and are usually formatted like this:

[+] [country code] [number including area code]

For example, a U.S. number with the +1 country code would go from 1 (404) 555-0123 to +14045550123 in the E.164 format. Several countries including the UK and France require a 0 before any number for local dialing. This must be removed in the international format.

In the U.S., the national number format includes only an area code and seven digits and are usually formatted like this: 

[Area Code] [Number]

Local and mobile numbers both follow the same format for United States and Canada numbers.

Number types

In many countries outside the United States and Canada, mobile numbers do not follow the same conventions as standard local numbers.

Local numbers are specific to a region and have a prefix that indicates which area they in.

Mobile numbers often use a different prefix than local numbers even if they were purchased in the same region.

This means that the cost of making a call to a mobile number often varies from the cost of making a call to a landline. CallRail's mobile surcharge rates apply to all tracking numbers outside of the US and Canada.
