9. NENA Company Registration Process
9.1 NENA Cmpany ID Registration Service
Wireless Service Providers and the FCC mandate placed upon them for delivery of location information
and the wireless subscribers callback number generates a need in 9–1–1 service for identification of the
relationship between the telecommunication company and telephone number. This need is driven by
two factors:
Data Base Management
• supports tracking in 9–1–1 data record processing and quality management by both the 9–1–1
service provider and the data source Company
• administration and management of error processes with multiple data providers
Speed of identification by PSAPs
• when a PSAP needs to quickly contact the originating Company for line interrupt, call trace,
and other emergency actions, the typical use of the NPA-NXX for Company identification
will no longer be effective
• an identifier that can be applied to each telephone number record is needed to support
individual telephone number portability
• a Company ID that associates 24 Hour access numbers with each telecommunications
company is needed for the above functions
9.2 Purpose of the NENA Company ID Registration Service
A national Company ID for 9–1–1 service will allow the PSAP to identify the Wireless Carrier serving the
caller, and to determine the 24 x 7 number of that Carrier for emergency contact needs. In the Company
ID database description, (below), each Carrier would identify one ID for each service area supported by
the same 24 x 7 contact number. If the Carrier has a national switching center that would take calls form
PSAPs for emergency assistance, the Carrier would need only one Company ID.
A national 9–1–1 Company ID registration point was recommended by NENA Standards work groups in
1996, and subsequent work has been directed to making this service a part of the NENA Web Site, for
general access. This approach is intended to support standardization of 9–1–1 Company Identifiers, and to
supply a single point of administration for the Company ID file content and update.
Use of the Internet allows telecommunications companies, state, county, city, and PSAP to access and use
the ID information. In addition, the design of this service allows each telecommunications company to
assign multiple IDs, so that individual service areas and 24 hour contact information can be identified.
Note: Use of the previously established NECA code was considered for the above functions.
However, NECA codes are numeric and not as immediately interpretable as are alpha IDs. In
addition, NECA codes do not apply to certain types of 9–1–1 call providing entities, such as
resellers and PBX operators, that are needed in 9–1–1 applications.
