# Managing phone number inventory
<a name="phone-inventory"></a>

The information in the following sections explains how to provision and manage the phone numbers used with Amazon Chime SDK Voice Connectors, Amazon Chime SDK Voice Connector groups, and SIP media applications.

When you change a user's Amazon Chime Business Calling phone number or phone number permissions, we recommend providing the user with their new phone number or permissions information. Before users can access their new phone number or permissions features, they must sign out of their Amazon Chime account and sign in again.
