All consultants who register as a new NAS user must have a letter of authorization (LOA) on file for each service provider for whom they intend to submit requests.  The LOA shall:

• be on the SP client’s company letterhead,
• provide the date the letter is signed,
• list the authorized consultant’s name (or consultant company name)
• specify that the consultant is authorized to access NAS on the SP’s behalf
• identify all Operating Company Numbers (OCNs), Parent Operating Company Numbers (OCNs), National Emergency Number Association (NENA)IDs, and Interexchange Access Customers [IACs aka Access Customer Name Abbreviation (ACNA)] under the ownership of the SP client that the SPC user has authorization to add to their user profile and submit and view data for in NAS, and
• contain the first and last name, email, and phone number of the authorized representative, and
• be signed by an authorized representative (e.g., officer of the company) of the SP client.

The LOA should be emailed to support@nanpa.com.

When an LOA is not on file for the SP client, the registration shall be rejected. When one or more Operating Company Numbers (OCNs), National Emergency Number Association (NENA)IDs, and Interexchange Access Customers [IACs aka Access Customer Name Abbreviation (ACNA)] under the ownership of the SP client is missing from the LOA, the item missing shall be removed from the SPC user’s registration.
