Non-Geographic Number
Short definition
Non-Geographic Number: A telephone number not tied to a specific city in the national numbering plan.
Meaning and how it works
Non-geographic numbers do not imply a specific city; charging and reachability rules vary by country. Telephone numbering depends on national rules, carrier capabilities and the selected calling route. Customers benefit from consistent dialling formats and reliable number reachability.
Business applications
- Business scenario:
A support number serves customers across regions without indicating one particular city.
What to check before implementation
Before deployment, verify geographical availability, permitted number formats, tariffs, caller-ID restrictions and both inbound and outbound calling behaviour.
