Setting outbound calling names - Amazon Chime SDK

Setting outbound calling names

You can assign calling names to the phone numbers in your inventory. This applies to toll-based numbers only, and excludes toll-free numbers. The names appear to recipients of outbound calls. You can update the names every seven days.


When you use an Amazon Chime SDK Voice Connector to place a call, that call is routed through a public switched telephone network to the telephone carrier of the called party. Some carriers don't support caller ID names, and some carriers don't use the Voice Connectors' CNAM database. As a result, a called party may not see calling names, or they might see a calling name different from the one you set.

US carriers are increasingly blocking or labeling phone numbers that exhibit spam or fraud characteristics, such as high call volumes and short or unanswered calls. To reduce the risk of your calls being similarly categorized, consider registering your outbound calls with the Free Caller Registry service.

The following sets of steps explain how to add outbound calling names.
