Number Portability

Definition

The ability to retain a phone number when changing providers under local portability rules.

How it works

Porting retains the number while changing service providers, but ancillary services and tariffs may change. Telephone numbering depends on national rules, carrier capabilities and the selected calling route. Customers benefit from consistent dialling formats and reliable number reachability.

Business example

A company moves to another carrier while keeping its familiar customer contact number where porting is supported.

What to consider

Before deployment, verify geographical availability, permitted number formats, tariffs, caller-ID restrictions and both inbound and outbound calling behaviour.
