Editing Talk:1129: Cell Number

: I guess this has something to do with keeping your phone number even when switching providers? We got a law in Norway around that time, which says you're able to keep your phone number while switching. Only difference is that here you can only tell, from the first two of eight digits, which ''provider'' you had in 2005 (or whenever it took effect). --[[User:Buggz|Buggz]] ([[User talk:Buggz|talk]]) 08:31, 2 November 2012 (UTC)

: According to wikipedia, mobile number portability was implemented in the USA in 2003.11.24. The comic would make sense with 2003, but why 2005? Maybe it only caught on enough in 2005: http://www.pyramidresearch.com/pa_may26_mnp.htm

: One reason for switching to a new "local" number would be so that those who have land lines aren't making "long-distance" phone calls to your cell phone. My brother just recently moved back from the east coast and is keeping his same cell phone number, which doesn't affect my other siblings and myself because we only use cell phones (which only count the number of minutes used). But my mom still uses land lines most of the time and so she's being billed for a long-distance call whenever she calls him, even though he lives about a mile away from her. But since most people are ditching the land lines, I think it'll be a moot point in about 5-10 years. --[[User:Joehammer79|Joehammer79]] ([[User talk:Joehammer79|talk]]) 13:45, 2 November 2012 (UTC)

It has to do with cell phones versus land lines. Back in the day (before the early 2000s), many people still had a land line as their primary or only phone. Your phone number's area code would be based on the area in which you lived. If you moved to a new area, you would get a new phone number, and if you moved out of the previous area code, a new area code. But with a cell phone, when you moved you kept the same number, including the area code. This was especially true after the 2003 law made it so you could keep the same number even if you switch your provider. The year 2005 has to do with when many people made their cell phone their primary or only phone. As [http://usatoday30.usatoday.com/tech/news/2003-03-24-cell-phones_x.htm this USA TODAY]article mentions, in 2003 18% of Americans with cell phones considered their cell phone their primary phone. Given the rapid growth of the industry, it is possible that 2005 is when more than half of cell phone owners in America considered their cell phone their primary phone.

:The details differ, of course ("your mileage may vary").  There are so many possible reasons why this occurs.  My parent's cell phones (612) don't match their home land-line (763) due to area code splits -- they didn't move or cause the disconnect themselves.  As for me, my first cell phone matched theirs, but in 2005 I moved to Michigan (586 area), creating a disconnect.  Then to make things worse, early next year (2006) I got a second line (and new phone) on my new girlfriend's account, and she lived on the other side of the city (734).  We married and moved near where I was living & working, but both still have "734" cell phones for family purposes.  So Randall's "living" can also be "dating / where significant other is living". --BigMal27 / [[Special:Contributions/192.136.15.149|192.136.15.149]] 15:54, 2 November 2012 (UTC)

For anyone from outside the US, the key fact here is that in the US, your mobile phone has an area code the same as a landline. I used to live in the US, and it blew my mind to learn that mobile phones had area codes there. I was like, but.... Huh? That's like saying your car has a postal address.[[User:Carlisle|Carlisle]] ([[User talk:Carlisle|talk]]) 15:06, 2 November 2012 (UTC)

:In the US, our cars kind of do have a postal address -- the state they are titled & registered in, the same state emblazoned on the license plate in the back (and sometimes the front also).  However, the states don't like it when you operate an "out-of-state" car in their territory for too long.  Specifically, you are using public roads that you are not paying for.  Then, when you transfer title and are assigned a new plate, you get a new letter/number combination.  License plates -- and specifically the random ID (or "vanity plate" custom ID) they hold -- are not portable between states. --BigMal27 / [[Special:Contributions/192.136.15.149|192.136.15.149]] 15:47, 2 November 2012 (UTC)

::In the past, in Italy you had to do the same when you moved from one province to another. Now, if you move, you pay car taxes to a different province, but your license plate stays the same. At the time, the province code was part of the license number, now it isn't anymore. If you have an old plate with a province code, you keep it even if you move.

I'm 34 and live in the USA and it still took me a while to understand this.  The 2005 date is because even though the portability law was passed in 2003, it was still difficult to do and not very common to keep you number until 2005.

-::::: This limitation was a relic of the "two letters, five numbers" system (the first and fourth digits still have to be 2 or above), which used two of all but two (QZ) letters on the numbers 2-9 to denote an exchange code, then five numbers, e.g. "KL5-5555" (KL being 55 here). Since there isn't a letter corresponding to 1 or 0, those combinations were used for area codes before seven-digit dialing became obsolete and the 407 exchange code (and 151{{Citation needed}} others), as well as the 847 area code (and 639{{Citation needed}} others), were introduced. I'm not sure which is more telling: that this was a thing, or that I know this before age 18. [[Special:Contributions/162.158.74.9|162.158.74.9]] 08:13, 13 April 2019 (UTC)

-Same here in the UK, with the MAC code. Car numbers changed a couple of times when they had to add a number because of having used up all the earlier ones. It meant all cars were registered on one day of the year, the same as race-horses. That made life difficult for car salesmen. So they did something else. I have no idea what and I am too old to care. I do recall that originally numbers had one of two letter groupings dividing the year.
-Caernarfonshire, for example, had JC and CC and the code was in bare metal on a black background. They changed that at the same time to black code on a reflective white background front (and yellow back. Unless I misremember.)

-== Bloated explanation ==
-There is a lot of information about the structure of US phone numbers here, and while general information is good to set up the joke, the specifics can be left to the wikipedia article. Specifically, all the talk of how exchanges are numbered and long distance charges is utterly irrelevant to the strip, and the information about choosing custom numbers is relevant only to the title text (and takes about one line to explain). The meat of the joke is that area codes used to be location-based but rapidly became more flexible around 2005, resulting in that rather arbitrary meaning today, yet this is mentioned almost casually in just one sentence near the end. I will trim and reorder the article so that it's more relevant to the comic shortly, unless there are objections. - [[User:Jerodast|jerodast]] ([[User talk:Jerodast|talk]]) 11:01, December 3, 2012
-:Quite a few explanations are like that. People add things that seem relevant to them, but don't really help explain the comic.

-==Additional Info on Phone Numbering Systems==
-I trimmed a lot of unnecessary information from the explanation, because it had nothing to do with explaining the joke of the comic. For those parties looking for more information on phone numbering plans, here is what I removed:
-*The middle digit of the area code was originally always 0 or 1 to allow mechanical dialing circuits to identify the sequence as an area code or not.
-*The next three digits are the exchange number (the middle digit being always 2 or higher), and the final four digits are typically random.
-*Business customers frequently could pay a premium for a specific number (if available), either to spell a brief slogan, or for easy memorization.
-The prevalence of digitally controlled dialing allowed the restrictions on digits in area codes and exchanges to be relaxed, suddenly making many new area codes and exchanges available. According to the {{w|North American Numbering Plan}}, currently:
-*The first 3 digits (Area Code) can be [2-9][0-9][0-9],
-*the next 3 digits (Exchange) can be [2-9][0-9][0-9], and
-*the final 4 digits (Subscriber Number) can be [0-9][0-9][0-9][0-9].
-There are [http://www.nanpa.com/area_codes/index.html some rules] for area code exceptions or reserved numbers though. Specifically, X11 codes are not valid as area codes (e.g. 411, 911, etc...) and Xyy (repeated last 2 digits) codes are reserved for special use area codes (e.g. toll-free/freephone 800, 888, etc..).
