How It Works

When a consumer calls a toll-free number from a carrier’s area:

1. The carrier’s switch receives the call and launches a query over VeriSign’s SS7 network.
2. VeriSign’s network routes the query to VeriSign’s 8XX database and identifies the appropriate carrier for the call, and other routing information as needed.
3. VeriSign’s network returns the response to the originating carrier’s Service Switching Point (SSP) for correct call routing.
