we just worked on a monster installation where there were multiple patch panel locations and telco rooms.

We labeled all the racks with a unique initial

for example the server room was -
SR that had 480 cat6 drops where I did 20 24 port patch panels in one rack. On the field side everthing was terminated on 24 port panels that went into cages.

So the numbering sequence was
SR 01-01 for Server Room patch panel 1 port 1.
While I agree that doing numbering in a way that makes sense is important, there is no way to future proof with 100% certainty.
