Resp Org Change (ROC) System
A system, maintained by the TFNA that enables Resp Orgs to administer TollFree Number Resp Org Changes and store the associated Letter of Agency (LOA) along with supporting
documentation in a centralized location. This system standardizes the process of Resp Org Change
management, submission, and processing of the change requests as well as provides access to the history
of the change transactions and supporting documentation. Affiliated Resp Orgs are not required to, but
may, use the ROC system. [ATIS-0417001-005, Industry Guidelines for Toll Free Number Administration]
