What do you mean by "one organization"?
If you're referring to an organization that regulates all (or almost all) utilities, Texas isn't the only state. Every state has some sort of utility regulatory agency (although they go by variety of names:
If you're referring to an organization that regulates landline telephone service, again, Texas isn't the only state. Almost every state regulatory agency (by whatever name) regulates landline service (I say "almost" because there's probably an exception somewhere; I've just never heard of one).
If you're referring to an organization that assigns area codes, no state, not even Texas, does this. Area codes in the United States are assigned by NANPA (
Actually, the format was N,(2-8),X. No area code can have 9 as the middle digit; these codes are reserved for some unspecified future use.
NANPA had probably assigned 361 to Texas as a relief code long before the TPUC even held hearings.
When NANPA assigns an area code, it has to consider several constraints:
- An area code can be used only once. A new area code can't conflict with any other area code anywhere in the United States, Canada, Bermuda, US territories in the Pacific, or a hodgepodge of geopolitical entities in the Caribbean.
- An area code can't (or at least shouldn't) conflict with any central office code within the area code; thus, for example, 573-573 would be a prohibited combination. Consequently, when a new area code is assigned, it must be selected from the list of presently-unassigned central office codes. That list is likely to be short: if an area code needs relief, it's already running out of central office codes. (And yes, I'm aware of the 847-847 exception to this rule.)
- An area code can't conflict with any of several reserved combinations: N11, N9X, NYY (second and third digits the same),
370-379, 456, 521-529, 555, 880-889, 950, 960-969.I suspect that 361 was one of these Geographic Relief Codes. I wouldn't be surprised if it was assigned back when the 512/210 split was under consideration.
Somebody here on TD once suggested splitting 202 by putting the federal government in 666.
NYC yes, Chicago no.
This issue invariably comes up in area code relief proceedings: if the wireless (paging, cellular, and PCS) companies are using up all the numbers, why not put them in their own "service-specific" area code?
The New York PSC adopted a service-specific overlay in New York City in 1992 when 917 was overlaid on 212 and 718. The wireless companies didn't like it because that "funny" area code put them at a competitive disadvantage. Furthermore, reaching a 917 number from 212 or 718 required 11-digit dialing, while intra-area code numbers were dialable with seven digits.
The next attempt to implement a service-specific overlay wound up in the FCC's lap. In this case, Ameritech wanted to overlay 630 on 312 and 708 in the Chicago area. The wireless companies protested to the FCC, asserting that service-specific overlays were not "competitively neutral." The FCC eventually ruled that Ameritech could implement 630 as an all-services overlay or a split, but not as a service-specific overlay.
If we're going to add any digits, I'd suggest adding a check digit to prevent wrong numbers. Similar to UPC codes.
That sounds like another "service-specific" scheme. Furthermore, how would a telco know what a given landline would be used for? Phone? Answering machine? Fax? PC modem? Alarm system? TiVo? All of above?
If we're going to have any type of service-specific coding, I'd suggest a code for coin phones.
Zenith (and Enterprise) were used throughout the country for operator-assisted calls to businesses willing to accept charges. I suspect that Zenith was chosen because it couldn't be dialed.
Are you sure? That totals eight digits. Source?
Well, I guess that's better than KRemlin.
Combinations in the form 58X were widely used as far back as the
1950s. In point: St. Louis (LUcas); Chicago (JUniper). Mark Cuccia's post "Recommended 'EXchange' Names" (TD 25:118, 03/26/06) lists the following 58X combinations: JUniper, JUno, JUstice, LUdlow, LUther.Well, we exhausted the original 144 area codes in 1994, so we had to adopt interchangeable area codes. Every area code introduced since
01/01/1995 is identical to a central office code in dozens of other area codes.Not necessarily. Some SxS exchanges used four-digit numbers (or four- and 5-digit intermixed). In point: Ann Arbor.
Once again: are you sure about eight-digit numbers? Source?
Neither was the second digit. Which is why N1X and N0X combinations were not used for central office codes. Which (conveniently) is why they were available in 1947 for use as area codes.
I don't follow that sentence.
[*] Many states have requested specific (vanity) area codes. Lexington, home of the University of Kentucky, is in UKY. Knoxville, home of University of Tennessee's Volunteers, is in VOL. In Florida, Daytona Beach has FUN, Miami gets SUN, and Cape Canaveral does the 321 countdown.Several Caribbean entities have commemorated themselves: Anguilla (ANG), Antiqua (ANT), Bahamas (BHA), British Virgin Islands (BVI), Grenada (GRE), Puerto Rico (PTR), St. Lucia (SLU), St. Vincent and the Grenadines (SVG), and Trinidad and Tobago (TNT). [Thanks to Mark Cuccia for this list.]
But Nevada couldn't get 777, so it had to settle for 775. Two cherries and a lemon.
In some area codes, unintentional vanity equivalents have arisen. In Chicago's northern suburbs, every VIP carries a BAG. Canada's northern territories are at the TOP of the world. In Utah, 385 spells ... well, I'll let you figure that out.
