What is the difference between Local, National, Mobile and Toll Free numbers?
Local, or geographic numbers are numbers that are assigned to a specific geographic region, or a city. For example London or Madrid. These numbers are typically used by local businesses.
National numbers are phone numbers that are not region-specific and are designed to be reachable from an entire country at the same cost. Since national phone numbers are not tied to a specific geographic location the geodata for a national number is usually listed as the country in incoming calls.
Toll-free numbers are numbers that are free of charge to call from the caller's side. The receiving party will pay charges on behalf of their customer to receive calls. Toll-free numbers are only reachable from within the country they are located in, thus with the same country prefix. In some cases, you may be able to extend the reachability. Toll-free numbers are also available in ranges, most commonly as +1-844-XXX-XXXX, or 888, 866, etc.,
Mobile numbers are assigned by country and in specific ranges so that they can be easily distinguished from local numbers. Please note that mobile numbers are not available for every country, as detailed in the table above.
