fixesiirrettävyyden

Fixesiirrettävyys, often translated as "fixed number portability" or "fixed line number portability," is a service that allows telecommunications subscribers to retain their existing landline telephone number when switching to a new service provider. This eliminates the need for customers to inform contacts of a new number or update business stationery and marketing materials. The process typically involves the customer initiating a port request with their chosen new provider, who then coordinates with the old provider to transfer the number.

The introduction of fixed number portability has been a key factor in fostering competition within the telecommunications market. By removing a significant barrier to switching providers, it empowers consumers to choose services that best meet their needs and budget, without the inconvenience of losing their established contact number. Regulatory frameworks in most countries mandate that providers offer this service to their customers. The technical implementation involves a central database managed by a neutral third party or the regulatory authority, which routes calls to the correct network based on the customer's current provider. This ensures a seamless transition for the user.
