ATIS 0300050

This document describes guidelines for the assignment of Carrier Identification Codes (CICs) in the North American Numbering Plan (NANP) area. The assignment practices detailed in these guidelines apply to the assignment of CICs made directly by North American Numbering Plan Administration (NANPA) to a specific entity. Therefore, the maximum number of CICs an entity may be assigned under these guidelines pertains to the number of CICs the administrator may directly assign to that entity. Accordingly, codes obtained via means other than direct assignment by the NANPA are outside the scope of these assignment guidelines. The requirements specified in these guidelines will apply to all CICs (e.g., the access and usage requirements for retaining CICs) regardless of the manner through which an entity obtained a code.
