About

The carrier for carriers.

Number Access is a U.S. telecommunications carrier providing the underlying network capabilities that power communications services.

We work behind the scenes with carriers, communications providers, and platforms, delivering access to numbering resources, voice, messaging, network intelligence, and infrastructure.

Our customers build and manage their own services and customer relationships. We provide the carrier infrastructure and connectivity that help make those services possible.

Go straight to the source.

We operate telecommunications switching and network infrastructure, maintain our own Operating Company Number (OCN), and serve as an authorized toll-free Responsible Organization (RespOrg).

Our capabilities include network routing, provisioning, interconnection, and programmatic service management through APIs and other supported interfaces.

By working directly with Number Access, carrier customers can integrate essential telecommunications capabilities into their own networks, platforms, and operations.

Built for the networks behind the networks.

Our focus is wholesale telecommunications. We support the providers that deliver communications services rather than competing for their retail subscribers.

From numbering and connectivity to intelligence and network infrastructure, Number Access brings essential carrier capabilities together through a single wholesale relationship.
