Partnerships are managed through instructions to ATPCO, and partner organizations may be other carriers or may be vendors such as a business process outsourcing company (BPO).


ATPCO's Partner Access Security System. Allows an organization (the partner) to view, print, create, or update changes to specified rules and footnotes of another organization (the owner). Partners with remote access will then be able to access the owner's data using their current sign-ons. This access is available for both public and private tariffs and both filed and unfiled data. To invoke access through this system, the owner must send an instruction in writing authorizing specific data for each partner. Now called Partner Access Control.
