11 Digit Dialing Comes Home to New York

Traicovn writes "The NY Times (free registration, yadda yadda) is carrying an article about 11 digit dialing coming to the city of New York for all phone calls, including inner city calls. Yes, that means even to dial across the street you will have to dial 1-xxx-xxx-xxxx. Eventually as the phone number system fills up because of more people having cellphones/pager/fax and a home/office phone line we may see this happening in more cities across the nation or the NANPA may have to intervene by making phone numbers longer in general."

      The difference is that with 10-digit dialing, all the local area codes are reserved and not used as exchange codes (the second three of the ten digits) in those area codes. Then it looks at the first three numbers you dial, and if they are not one of the local area codes, it does 7-digit dialing.

      Why 11 vs 10 digits? I can only think of two reasons. Either there are enough area codes in the local area that they don't want to waste the exchange codes, or they need a new area code and don't want to force the people who have it as their exchange to change their 7-digit number.

      And now that I've gone all through this, the sometimes-10, sometimes-7 digit dialing that IIRC is used in the Dallas Metroplex area vs always-10 digits still doesn't make a case for needing the 1 in front. In fact, without the 1, 7-digit dialing could still be assumed. So I'm still just as confused as you are.

      Yeah, same in Boston. We recently got some new area codes added to our local calling area, so we have to dial 10 digits instead of the previous 7. We certainly don't have to dial the '1'.

      By contrast, however, in Rhode Island (401 for the whole state), when New England Telephone became NYNEX (yes, it was always a subsidiary, but when they actually changed the name), we had to dial '1' + 7 digits if we were calling outside our local calling area, but within 401. Then they became Bell Atlantic, and we had to dial 1+401+7 digits outside the local calling area (but within 401). Then they became verizon, and now you just dial 7 digits anywhere within 401, and it's up to you to remember whether it's a local call or a toll call.

      So, I think basically the "1" is at the whim of the phone companies, and it is no longer the reserved digit signifying "long distance". Unless of course the NYT got it wrong. Someone who works for the phone companies (or has hacked into their switches - Hi Kevin!) should explain to us why New Yorkers need to dial a 1 when they have overlay codes, and those of us elsewhere (Boston, DC) don't.

So your business would have 9 PRIs coming in, for a total of 216 channels. A PRI channel allows for an outgoing call, but it does NOT have its own phone number. The way it works is that the business buys a block of DID numbers, however many they need, and those get routed over the PRI. An incoming call to one of those numbers uses whatever channel is available and sends a signal to your PBX identifying which number was dialed. This is much more efficient and cost effective than the single line / phone number model.

When they deregulated the phone system in this state, lots of companies bought up these blocks but never resold anything close to same amount to end-customers. The result (at least in Philadelphia) is that we now have 6 area codes for the city (215, 267 and 445) and suburban (610, 484 and 835) areas although there hasn't been a net gain in population in this region (mostly people moving out of the city and into the suburbs).

      > Why are we running out of phone numbers?

      It has to do with the fact that service providers are assigned blocks of numbers, rather than individual numbers for their subscribers. So imagine two service providers A and B. Maybe they both get a single 10,000 block of phone numbers. Imagine that A has 9,000 subscribers (and thus has used 90%) of their numbers, and B has 1,000 subscribers (and has used 10%). If A gains another 2,000 subscribers, they can't use B's number block. They have to apply to the FCC for another block of 10,000 numbers. In the meantime, B is has plenty of room. As a result, you run out of numbers, even though they're not all being used.

      Their is a concept called Number Pooling that means that if a service provider has a block of 1,000 numbers that they aren't using, they have to return that block of numbers to the "pool" for other service providers to use. Number Pooling is mandated in many areas under specific circumstances.

      The telecom industry is slowly getting away from the idea of number block routing. With Number Portability and Number Pooling, they're moving towards a system that improves on that. Number blocks are "tagged" as having a subscriber that no longer has service with the service provider that owns that block. Then the switch goes to a centralized database and determines where that subscriber is, and the call is routed accordingly.

      Number Portability exists in a limited extent today, so in many areas of the country when you move between service providers (but stay in the same service area), you can keep your phone number. So the situation is being alleviated, but New York is probably the biggest market in the country, and things are pretty strained there.

      Telecom companies are working on this. A concept called ENUM allows subscribers to be assigned IP addresses that are abstracted from the ways the actual call is routed. This is mostly coming about because of VoIP, but it has merits with regular E.164 telephone numbers as well. The telecom industry moves a little slower than the computer industry, so expect to see something like this within 3-5 years. Happy waiting!
