I am doing a site by remote site survey for a client and trying to
find out all the individual telecom service providers. I have all the
address and number info, but I can only verify about 60% with the
bills accounting has provided me.

Is there a way I can find out who the provider is for any given local
access number? I recall doing something similar for long distance
once, but don't know if there is a reverse number lookup that will
give me the carrier.

thanks in advance

I believe this is what you want - you enter NPA and NXX, and it outputs the
City, Telco, and the serving office CLLI. One of my customers put me onto it
and some other useful sites which I haven't used in so long that I lost the
links.

Do a google search on "npa nxx telco" and you can find many more goodies.

Probably not.

The Local Calling Guide is the best free source of this kind of info
that I know: http://members.dandy.net/~czg/lca_index.php

It is quite accurate except for numbers that have been ported. If you
really want to know who the serving carrier is, you need access to the
LNP database. For example, I have a 607-330 number. If you look it
up, the tables say Paetec which was correct until earlier this year
when I ported it to Level3, but without checking LNP, there's no way
you could tell.

telcodata.us will decode NPA/NXX but won't help you if they've ported
from an ILEC to a LEC or LEC to an ILEC or to a mobile operator.

very impressive... Can anyone confirm that it reports LNP numbers correctly?

It doesn't. I looked up my ported number and it reported the switch
where it used to live, not the one where I ported it to.

It does not. I just tried a ported number, and while it provides info
about porting eligibility, it did not point to the correct serving
carrier (instead, it pointed to the originaly LEC serving taht number,
before porting).

Same thing happened to me when I did my number.

Hello all. 1st time poster.

I just tried this search, as I would be awesome to have a tool as powerful as being able to look up any company's carrier. My number was never ported, it was a fresh install assigned from itc deltacom. When I did the search above it came up paetec. Again the number was never ported, so this is definitely a dodgy, non-reliable database.

Just a note to all the telco experts. There are no public readily available databases that allow you to identify the carrier for a ported number. Ported number lookup requires an SS7 network lookup from the central office switch. The carrier who was assigned (and paid for) the NPA NXX is still the code holder or LERG assignee of the exchange, a ported number is an exception to the assignment at the subscriber level.
