N11 code

This U.S. road sign alerts highway users to the availability of 9-1-1 service.

An N11 code (pronounced Enn-one-one) is a three-digit dialing code used in abbreviated dialing in the North American Numbering Plan (NANP). The mnemonic N stands for the digits 2 through 9 and thus the syntax stands for the codes 211, 311, 411, 511, 611, 711, 811, and 911. These dialing codes provide access to special local services, such as 911 for emergency services, which is a facility mandated by law in the United States. The (FCC) in CC Docket 92-105, specified how the N11 codes of 211, 311, 511, 711 and 811 codes would be used for various types of public information under NANP.[1][2]
