Is there a site that will tell you which cell phone provider owns which number?
For example if I want to find out which company owns (212)924, also written 212.924 – the 924 number in the 212 area code – is there a site that will tell me this?
Are you talking US phone numbers?
If so, do you mean a site that would tell you who owns an individual phone number like (123) 456-7890, or do you mean a site that would tell you who owns all numbers starting with area code 123 and first 3 digits 456, i.e. (123) 456-XXXX?
If the former, I don’t know. If the latter, then I’m sure you realize that you couldn’t say which cell phone company owns (123) 456-XXXX since the numbers starting with (123) 456-… could belong to a variety of cell phone companies.
I presumed one company would own all the 456 numbers.
I’m trying to find out which co. owns a certain number.
It used to be that way, but not anymore. Customers “own” their number and can take it from provider to provider as they switch plans.
I just found out what I wanted to know using this site:
It’s not accurate. It thinks my number is still with T-Mobile. I’ve been with AT&T for over 2 years. It still thinks my dad’s is a landline, when he ported it to his cell over 4 years ago. I think it’s referencing who originally had the number in their pool. It certainly doesn’t have much bearing on reality today.
Exactly. For quite a few years now, phone numbers have not been tied to particular cell phone companies.
true, but what percentsge of cell or landlines have switched ca carriers? 5%, 10%?
Just going by my immediate family, all of them. 
The area code and first 3 digits of my cell phone number ( (780) 237 ) aren’t even in that list.
The short answer is no. I work in building out SMS applications and such for mobile phones and we are charged a lot of money by the carriers every time we look up a phone number. I think it is something like 7 cents per lookup against (relatively) real-time carrier tables. I don’t know of any place to find this info for free. And other posters are correct in that just trying to find what carrier owns ‘a block’ of phone numbers is not really relevant anymore since number portability came along. The carriers and aggregators make alot of money charging service providers for this data (which is basically free to them), so they are not going to let this info out anywhere else.
It’s not just that- that list is also really, really out of date. It has my number pegged in more or less the right geographic area, but thinks it still belongs to Aerial Wireless. Aerial hasn’t existed for about 10 years, since its assets and subscribers were purchased by VoiceStream in 1999 - which soon afterward became T-Mobile. I’ve had the number since 2001.
Same here. Thinks I’m TMobile, I’m AT&T for over 2 years.
From their FAQs:

Perhaps you didn’t notice that they have a FAQ page, which says:
Which would be why I quoted him.

Is that correct? I knew I could port my cell phone number over to another supplier. I’ve also ported a landline between carriers, but the phone physically stayed in the same house. This part of the FAQ seems to be saying that I could take a phone number assigned to a landline in Chicago, and port it over to a carrier/landline in Ohio. If that is possible, how are long distance charges figured? Based on the original phone number locataion, or the current one?
I don’t think you can port a number between area codes. If it’s a (say) 555 number in Chicago it’s a 555 number in Indianapolis and anyone in Chicago who wants to call you gets to pay long distance rates.
My sister and her husband moved from San Diego to Boston a couple of years ago. They chose to keep their phone numbers the same and just have the company send the bill to their new address in Boston. My plan includes long distance so I don’t know how that sort of billing works anymore.
