But it’s also why heavily populated areas have certain area codes. These numbers were just faster to dial. For instance:
212: Manhattan
213: Los Angeles
214: Dallas
312: Chicago
313: Detroit
314: St. Louis
321: East Central Florida
323: Also LA
332: Also Manhattan
413: Pittsburgh
415: San Francisco
Generally, if the area code took less time to dial, odds are it’s an urban code. The emergent pattern is when middle digit is 1 or 2. Like 816 for KCMO or 918 for Tulsa or 416 for Toronto.
And if it featured higher digits or a zero, it was probably rural. Area Code 907 was established in 1957 for almost all of Alaska. That’s 26 total pulses. 906 is for Michigan’s Upper Peninsula and was put into service in 1961 after splitting off from 616, which services Grand Rapids.
Many of the high digit urban area codes were put into use after touch tone dialing became widespread since any number took just as long as any other to dial.
One thing I thought was funny about the way phones used to work is 5-digit dialing. So I reckon that larger towns in the area code got lower numbers as the third digit in their exchange codes because those dialed fastest, but I don’t know that for sure. What I do know is the town where I grew up has a population of about 400, and that digit is 9. The next town over is the county seat with a population of 20,000, and its original exchange codes end in 1 and 2.
Also, if you were in a rural area that had the LATA code (the first three numbers after the area code) on a mechanical switcher, you did not have to use the LATA code. Could just dial the last 4 digits. My dad’s farm was in a town that was still sitting on a mechanical switch until the early 2000’s so in the early 80’s we had a budget party line (we were one long ring, while the neighbors had two shorter rings and there was a third person - whom we did not know, that was a phenomenally LONG call maker - you’d sometimes have to wait an hour or so for the guy to get off the line) and all of our friends were just 4 numbers… Can remember many - 8345, 8652, 8033 (<- my best friend in 10th grade…)
It was a decidedly different, and less expensive, world.
I knew about 5-digit dialing, but never knew people used to dial only 4 digits. That’s pretty neat, and probably made life with a rotary phone much easier than people my age realize.
I’m a younger millennial so it was no big deal to grab the landline and dial 1+10 digits to call my girlfriend long distance in 2009. On a rotary phone, it’d probably have taken til supper just to dial lol
I did find a rotary phone in a box at my great grandmother’s house once and played with it because it was fascinating to me. Then I dialed a random 800 number on it and remarked that it was kinda amazing that so many people bought things over the telephone in the day.
Yup… the trick was having your LATA code be on the mechanical switcher. They could address 9,999 numbers. Which in a town that at the time had maybe 1,900 people… it was glorious.

TIL, thank you for that!
