VeriSign Number Portability services deliver essential network and database capabilities so providers can quickly, easily, and accurately port numbers, route calls to ported numbers, and process orders when subscribers change service providers.

Carriers may choose our complete solution or select individual components to address specific needs.

Service Order Administration (SOA) >>

Interconnects with all regional North American Number Portability Administration Centers (NPACs) so carriers can streamline order entry and ported number provisioning.

• Data Access supports traditional and IP protocols, and query methods for wireline and wireless networks, so carriers can ensure accurate and efficient call routing for ported and pooled telephone numbers.
• Inter-Carrier Communications Process (ICP) manages wireless-to-wireless pre-porting within the industry-specified 30-minute porting interval. VeriSign ICP is fully integrated into the VeriSign SOA application so providers can manage all porting processes from a single interface.
• Line Ownership Validation Service automatically validates a telephone number's network service provider owner prior to submitting a port request, so providers can reduce errors, improve productivity, and speed service delivery.
• Wireless Number Portability-Local Service Request (WNP-LSR) supports wireless-to-wireline pre-porting activities. The service is fully-integrated with VeriSign Service Order Administration and Inter-Carrier Communications Process services, so all porting processes can work together seamlessly.
