There is no need to have a Snowflake account in the target region, a share will be created for each user.

The listing is replicated into all selected regions automatically, the data is not.

The user must have the ORGADMIN role available in at least one account to link accounts for replication.

Shares attached to listings in remote regions can be viewed from any account in an organization.

For a standard listing the user can wait until the first customer requests the data before replicating it to the target region.
