what does the input friend id Mean in aut private servers

In AUT private servers, “input friend id” usually means you need to enter your friend’s Roblox user ID so the server can recognize which friend to invite or let you join. The ID is the numeric part tied to their Roblox profile, not their display name.

What it does

• It links the private-server feature to a specific Roblox account.

• It helps the game find the right friend when names are similar.

• In some cases, it may be used together with the server code or join-invite system.

Where to find it

• Open your friend’s Roblox profile and look for their user ID.

• If the game also gives you a private server code, that code is separate from the friend ID.

Simple example

If your friend says, “Send me your friend ID,” they usually want the number from your Roblox profile so they can add you to the AUT private server list or use the join feature correctly.

Note

Some community posts also mention that joining friends in AUT can be confusing because private servers and quick-join options do not always behave the same way.

[2] TL;DR: it’s usually your Roblox user ID, not your username, and it’s used to identify you for the AUT private server system.
