Setup and activation

Purchased and ported-in DID numbers remain assigned to your account until they expire, are removed, or are ported out. After assignment, DID numbers often require additional configuration before they can receive inbound calls, receive inbound SMS messages, or activate additional services.

The My Numbers section combines DID number management into one workspace. It shows DID number status, time left, assigned trunks, identities, supported services, capacity, and available actions for single-number and batch updates.

A DID number may already belong to your account but still require configuration before inbound traffic can be delivered. Common reasons include missing inbound trunk assignments, insufficient inbound capacity, required end-user verification, pending service approval, or renewal settings that allow the DID number to expire.

The following flow shows the typical initial configuration process required before a DID number can receive inbound calls or inbound SMS messages.

After a DID number is configured and active, My Numbers is also used to manage renewal behavior, billing cycles, capacity changes, service configuration, end-user verification updates, and lifecycle actions such as removal or restoration.

DID number setup can also be automated with Configuration profiles, which applies reusable voice trunk, SMS trunk, and capacity group settings to DID numbers.

For status, trunk, and verification values, see My Numbers reference.

For task-based instructions, see How-to guides. For actions that can be applied to multiple selected DID numbers, see Batch actions reference.
