Local Service Request (LSR)

A Local Service Request (LSR) in the telecommunications industry is a formal request submitted by one telephone service provider to another when a customer decides to switch providers but keep their existing phone number, known as Local Number Portability (LNP).

The LSR is used to initiate and facilitate the process of transferring services from the current provider to the new provider. 

  • Initiating Service Transfer: An LSR is typically submitted by the new service provider to the existing provider on behalf of a customer who is switching services. This request includes necessary details for transferring the customer's phone service.


  • Required Information: The LSR contains various pieces of information, such as the customer's name, billing address, service address, and the specific telephone numbers to be ported. It may also include desired service features and billing information.


  • Number Portability: LSRs are a critical component in the process of Local Number Portability, enabling customers to retain their telephone numbers when changing service providers within the same geographical area.


  • Regulatory Compliance: The process of submitting and processing LSRs is governed by telecommunications regulatory bodies to ensure fair and efficient handling of service transfers.


  • Processing Time and Coordination: The process of completing an LSR can vary in time, depending on various factors such as the accuracy of the information provided and the coordination between the involved service providers.

The Local Service Request is a fundamental tool in the telecommunications industry, ensuring a smooth transition of services for customers switching providers and maintaining the integrity of the Local Number Portability process.
