Number Formatting - Input

Overview

When making your request it is possible to force your telephone number to be formatted into the E164 format (also known as international format) which is necessary for us to use when sending your telephone number to the network operator to obtain a result.

You can include the input_format parameter within your request adding in the 3 letter ISO code for the country that your telephone number belongs to.

This is useful if your stored telephone numbers are stored in their local format as means you don’t have to edit these before making your API request.

The below table details how this works and the result you should expect.
