Anyone know what this means?

I was just looking at my invoice for our January trip to get a break down of the prices so our 3rd in the room can pay us for it and I noticed next to the ressie it says "ZMB" is that a code?> Did the CM apply it without letting em know?? Thanks to anyone who can answer my question!

That is just a rack rate code.
