FiveM builds a hardware fingerprint from your PC and sends it to each server you join. When a server or its anti-cheat bans that fingerprint, a new account alone will not help — the same machine is recognised on sight. This guide covers what FiveM reads, how the fingerprint is stored, and what has to change for a fresh start.
When you launch FiveM, the client gathers a set of values from your hardware and Windows installation. These are hashed into a fingerprint that travels with every connection attempt. The server never sees the raw serial numbers — only the hash — but the hash is enough to match against a ban list.
The identifiers FiveM uses are not published in its documentation, but the community has reverse-engineered the set over the years. It typically includes disk serials, network adapter MACs, motherboard serial, and Windows-level IDs.
There are two layers. A server ban is set by that server's administrators and applies only on their server — other servers do not see it. A global ban is set by the FiveM team itself and applies everywhere: every FiveM server rejects the fingerprint.
Both work the same way technically — a hash stored against a deny list — but the scope is different. A server ban means the admin decided you broke their rules; a global ban means FiveM decided you broke theirs.
Because the ban is tied to hardware, you need three things for a genuinely clean connection:
A spoofer handles the first requirement: it changes the identifiers before the fingerprint is built. The best tools also handle the second and third — unlinking accounts and removing the old install — so the whole process is one step, not three manual ones.
