What is COCAG (Central Office Code Assignment Guidelines)

COCAG (Central Office Code Assignment Guidelines) refers to a set of guidelines and regulations established by the telecommunications industry to govern the assignment of central office codes. Central office codes are the three-digit numbers used to identify central offices, which are the physical locations where telephone lines are terminated and connected to the public switched telephone network (PSTN).

The purpose of COCAG is to ensure fair and efficient allocation of central office codes to telecommunications service providers. These guidelines are developed and maintained by the North American Numbering Plan Administrator (NANPA), which is responsible for the administration and assignment of telephone numbering resources in the United States and its territories.

COCAG provides a framework for the assignment of central office codes based on various factors, including geographic boundaries, projected demand, and industry best practices. The guidelines outline the procedures and criteria that service providers must follow when requesting new central office codes or modifying existing assignments.

One of the key aspects of COCAG is the concept of conservation. Due to the limited availability of central office codes, it is essential to ensure their efficient use and avoid unnecessary depletion. COCAG encourages service providers to implement number conservation measures, such as number pooling, which allows multiple service providers to share a single block of central office codes.

COCAG promotes transparency and fair competition by establishing rules for the distribution of central office codes. The guidelines specify that central office codes should be assigned on a first-come, first-served basis, ensuring equal opportunities for all service providers.
