Managing site codes
After adding multiple sites to your account, you can optionally assign a site code to each site. This allows users to easily identify and dial users in the same site.
Assigning site codes will cause the following changes to phone users' extensions:
- Site codes will be prefixed to each extension number that belongs to that site.
- Existing extensions will be shortened (known as the short extension) so that they don't exceed the 6-digit limit. Users can dial the short extension to reach users in the same site.
- The long extension is a combination of the site code and short extension. This can be used by external callers or phone users in other sites.
- Site codes can be 1 to 6 digits. Since there's a default 15-digit limit on extensions, the short extension can be up to 9 digits. If you require longer extensions, submit a request to Zoom Support.
