The
UID
of a player is a unique identifier that helps distinguish players from each other in
Co-Op Mode
. UIDs are used primarily for joining other player's worlds, but UIDs can also be used to add people to the friend list and blacklist people from joining other's worlds as well as identify which server a user is playing on.
A UID consists of 9 to 10 digits. For a 9-digit UID, the first digit (“UID Prefix”) indicates the server the player is located on, and for a 10-digit UID, the first 2 digits. The other 8 digits are a number distributed according to account creation order.
If the player is playing on the internal servers, which has UIDs start with 0, UIDs may be less than 9 digits long as it does not display leading zeros.
