The gate addresses are the names used in the shows.

Note, for destinations known by multiple names, either name could be used, so make sure you try all of them!

The list is near show complete!
Some well known ones are also in the works.

There are over 620 addresses!
For those that want to see them all:

Note, names will slashes (/) can be addressed by either. Make sure you try all of them!

An undocumented feature exists: Set the DHD name to AutoDHD, and it will automatically dial the closest Stargate. This can be useful to find nearby gates.
This feature may change in the future.
