ESCO Code Selection
Full Name:
NENA Standard for Emergency Service Central Office (ESCO) Code Selection, Assignment and Display Management
Document Type: Standard
 Number: 03-007 v1 (archived)

This NENA Recommended Standard for Emergency Service Central Office (ESCO) Code Selection, Assignment and Display Management discusses the Emergency Service Central Office (ESCO) code specifications as it relates to the incoming trunk groups in the E9-1-1 Control Office. It is a guide for designers, manufacturers, 9-1-1 Service Providers, 9-1-1 Database Authorities and 9-1-1 Public Safety Answering Points (PSAPs). It identifies some of the issues involved with the selection, assignment, processing and management of the ESCO codes used for trunk group origination identification during an Automatic Number Identification (ANI) failure.

This document is published by NENA as a guide for the 9-1-1 community and related industries. It is not intended to provide complete design specifications or parameters related to E9-1-1 Control Office trunking translations or database specifications nor shall it serve as an exclusive procurement specification.

Use of this NENA Recommended Standard for Emergency Service Central Office (ESCO) Code Selection, ssignment and Display Management as a guide will:

  • provide consistent management of ESCO code resources;
  • provide for consistent display of information; and
  • permit the PSAP call taker to rapidly identify the "source” of the call in a situation where
    there was no ANI provided.
