Good Morning,
Before our directory gets too big I wanted to have a conversation about extension organization. I had a few questions and wanted to see how others were breaking this down.
What system do you use in your mesh? Is it a guess by golly or well thought out numbering pattern?
Thanks in advance!

Here in Northwest Ohio, we have set up the following numbering plan that can be extended theoretically nationwide. It's pretty simple. <State><County><Extension>, so I have 17-48-017, and someone just across the line from me might have 26-58-123. State is just the two digit number, in the order they joined the union, county is the way the state assigns the county number, in both Ohio(17) and Michigan(26), that's alphabetical order. We figured 1000 extensions in a county was probably good around here, but if you're in a really populated area, you could make that bigger. We have one person managing assigning the extension numbers for the region just so we don't have duplicates. If your area would like to adopt similar, you're welcome to. In any case, I recommend talking to others around you to make sure that everything is compatible.
That's a solid option.
Any others?
On a PBX network I put together called "MeshPhone", we have a 4-digit dial plan for local calling and a 7-digit plan for network calling. Your network number is your 4-digit local number prepended by your Area Code, which most people can readily understand.
Thus, my shack extension is 2111 and my MeshPhone number is 973-2111.
Locally, to call up my NOAA Weather Radio, you dial 2199 and from the network you call 973-2199.
There's about 40 PBX's scattered around the world on the network. International locations use their 2-digit country code prepended by a 0 or 1 plus their 4-digit extension instead of Area Codes which are only used here in the States, Canada, and certain Caribbean countries.
PBX's using 3 digit extensions are prepended by their Area Code and a dummy digit to round out their network number to 7-digits.
Of course, local pbx's can get together and devise their own dialing plan for their community of interest. The main thing is that the dialing plan of one pbx can not overlap the dialing plan of another pbx. And, this can transcend Area Codes. A few years ago I devised a plan for the state of Tennessee which is now working well in practice. 4-digits for the whole state and Area Codes depending on county (mirroring what is done in the telephone network).

Example:
KD1HA = 53142
KB1JFG = 521534
N2MH = 6264
KF7VOL = 537865

Thanks guys and be safe out there!
Just found you post, though I share our dialing plan.
In our mesh network, we use a 6 digit dial plan. We have several counties following this.
https://willamettevalleymesh.net/map.html
First digit = 7 (Oregon call area)
Second digit = ARES district number
Third digit = County designation
Digits 4/5/6 = County's choice for delegation

I have also provide the pdf file showing how numbers are assigned.

Use a 7 digit number.
ZZZ-YYXX
ZZZ=North American area code (https://www.att.com/ecms/dam/att/smb/help/pdf/Area-Codes-N-America-by-State.pdf)
YY='office code'
XX='extension'
Warner Robbins GA might be 478-YYXX
