Geographic Number Portability (GNP) is a process that allows users to transfer their fixed phone number from one telephone provider to another while retaining the same geographic area code. This capability is similar to Mobile Number Portability (MNP) but applies to fixed phone numbers assigned to a specific geographic area rather than mobile numbers. GNP allows users to switch providers without having to change their phone number, facilitating competition among fixed-line providers and improving consumer choice.

In everyday life, Geographic Number Portability is beneficial for users who wish to change their fixed-line provider without losing the phone number associated with their residence or business. For example, if a company decides to switch providers for better rates or services, GNP ensures the phone number portability, guaranteeing continuity in communications with clients, suppliers, and other contacts. This flexibility is crucial for businesses that do not want to incur the costs and inconveniences associated with changing phone numbers and communicating with their stakeholders, or for private users who risk losing contact with relatives and friends.

In Switzerland, Geographic Number Portability is managed and regulated by the Federal Office of Communications (OFCOM), which oversees the process of number portability for both fixed and mobile numbers. Switzerland has implemented geographic number portability to promote competition in the telecommunications market, allowing users to switch providers without losing their phone number. This process is standardized and regulated to ensure that the transfer of numbers is efficient and seamless for both users and the involved operators.
