NENA Standards


NENA Recommended Standards are developed by the NENA Technical Committees: Network, Data, PSAP/CPE and ALEC/PS. Once approved by the NENA Executive Board, these recommended standards help ensure consistency in the 9-1-1 industry. Telcos, vendors and users all benefit from widespread adoption of the recommended standards.

Please note: All NENA Standards are now available for download as Adobe PDF files, which you will need Adobe Acrobat to read.  If you do not have the Adobe Acrobat reader, you can download it free at
