We have a similar numbering standard that we have used for over a decade. Im just over it. Same with all the time making custom length patch cables but thats another thread. During commissioning and service calls i just want to read a plain English label and not have to have a printed out spread sheet and schematic to remember that "MK" is the marketing department and not Mary Kays office or the Michael Kors store or Mikes Kitchen or whatever.

Marketing
WI-FI AP
Switch 1 Port 5

Is easier for me to read. On remotes and touchpanels i include the IDs/IPs/Gateways whatever so that i dont have to carry around a book of documents. I started dumbing the labels down about 3 years ago and its made my life so much easier.

101-02-06
101=Room ID
02 = Location in the room (2nd drop)
06 = 6th cable in that bundle
203 would be 3rd room on the second floor.
500 are my outside runs
900 are my unknown cables
010 are usually patch cables within closets or racks, etc.

Would love to hear your thoughts on this. I created a new thread.

For us, each cable should include a unique wire number. A scheme like Mario's is good. It must also include the following info so that you would NEVER need some type of decoding document to figure out where it is going:

From location, device, connector > Dest location, device, connector

I prefer to put all of that on a single row that repeats around the cable so you never have to twist a wire to read all the info. Others prefer source info on one row and dest info on the next.

ie:

1321 RK3 RTR OUT 7 > RK1 MON IN 2
