# Getting a service ID

A numeric service ID is used to internally guarantee uniqueness of services.

To register a new service with NMS Communications, contact Technical Services and provide them with the service's three-letter acronym and a description of the service. Technical Services will verify that the acronym is unique and assign a service ID.

During service development and testing, assign any three-letter acronym and service ID to the service. When the service is ready to be published, register the service with NMS.

The service IDs for services supplied by NMS range from 0 to 0x40 (this includes services such as ADI, VCE, SWI). IDs for services not supplied by NMS typically range from 0x41 to 0xFFF.
