ATIS Acts to Better Identify Fraudulent Port Requests

ATIS Acts to Better Identify Fraudulent Port Requests

ATIS solutions are critical in the industry’s work to mitigate illegal use of our communications infrastructure and the recently published Supplement A to the Unified Ordering Model (UOM) Volume II – Analysis – Wireless Intercarrier Communications Interface Specification (WICIS) for Local Number Portability Version 5.0.0 (ATIS-0409001-0500) allows service providers to better identify port requests that may be fraudulent.


This action was taken to address the rise of unauthorized number porting, including impacts to intermodal porting. In a brief addendum, Supplement A to WICIS Version 5.0.0 takes RCODE 6B, previously reserved to indicate “same new and old network provider” and repurposes the usage to indicate “Fraud Prevention/Customer Action Needed”. The WICIS defines the operational requirements and technical specifications for the exchange of information needed for the Intercarrier Communication Process (ICP). While the modification to RCODE 6B was made in Supplement A, there were no changes to WICIS Version 5.0.0.

The WICIS is created by ATIS’ Ordering and Billing Forum, the ICT industry’s go-to resource for resolving issues and developing documents to enable automated exchange of information needed to support Local, Access, and Wireless service ordering, along with the standards for inter-company billing and record exchange, for IP-based and TDM-based networks.
