@qbteachmt "I recently came across a great comment: cell phone #s are the new tribal indicator. The area code tells other people, "This is the land I came from." "

Arizona used to have just one area code:  602.  (If there was a zero in the middle, you knew it was a single-code state.)  Then we grew and needed two.  Then three, then four, then five..  For land lines, there were boundaries.  But if you lived in a cheap neighborhood you could still get a cell phone with a 480 area code (Scottsdale, among other cities).  602 was down to just Phoenix itself.  Glad I got my office and cell numbers there, while still available, and I don't plan on giving them up even if I move.  

But now, they have run out of 602 numbers, so any new subscribers in the metro area are assigned a 480 or 623, even if they live in the city.  And this means that we all have to dial 10 digits, even if to the same area code. All my "saved" numbers on my office phone have to be edited to include the area code. 

I had a problem with my bank.  (It's the largest private bank in the country, headquartered in Oklahoma.)  My complaint went to the regional manager, who started his career in Texas.  He called me on his cell phone, which had a Texas area code.  That's fine, if you're calling back from a cell phone, but I still have a land line at my office, and if I call a foreign area code, I have to pay by the minute. I suppose I should drop the land line.  I used to keep it, because they told me I needed it for the alarm system.  But now my alarm has its own cell phone number.  Which makes it hard to explain, when grandkids ask about those old movies where the criminals first cut the phone cord.
