A short name is a unique, simplified identifier for the org in Genesys Cloud. The short name is based on the company name that is entered when the org is activated. Users see the short name only when they log in.  

Genesys Cloud checks if the org short name is unique within that AWS region. However, Genesys recommends using a unique short name for each org and not reusing a short name of an org in a different AWS region.

Note: Once the org is activated, the short name cannot be changed. To change the short name, create and configure a new org.
