The three numbers after the area code are commonly referred to as the NXX - short for Central Office (exchange) code. Often considered part of a subscriber number. The three-digit Central Office codes are assigned to a specific CO serving its customers, but may be physically dispersed by redirection, or forwarding to mobile operators and other services. To learn more about how the telephone numbering system works in the USA, go to http://en.wikipedia.org/wiki/North_American_Numbering_Plan or http://en.wikipedia.org/wiki/445

The term exchange area can be used to refer to an area served by a particular switch, but is typically known as a wire center in the US telecommunications industry. The exchange area is usually the combination of the area code and the NXX. The exchange code or Central Office Code refers to the first three digits of the local number (NXX). It is sometimes confused with the area code (NPA).

    • This number calls here frequently.  From some of the posts on this site, I believe them to be a collection agency.  Since I am up-to-date with my bills, they have no reason to be calling me.  Mostly, when I do not pick up, they hang up.  Occasionally, they leave a recorded message which says, This is an important message for, and then the idiots do not state the name.

    • I  received several phone calls from these people. Each time I tell the person, who I speak with, that I do not know who this person is, that this person does not live here, and asked them to remove this phone number from their files.  This morning's call  I am spoken to very rudely and asked several times where this person is-indicating that I am lying to them.   I became very angry with the person calling and told them in no uncertain terms that if I receive another call from them that I will report them to the phone company and police.  Then I will contact my attorney and press harrassment charges.

    • I just got a call from this number, the answering machine picked it up and then I heard a request for someone who had passed a couple months ago. I picked up and pressed 9 and right away got a rep but I asked him who he was and why he was calling then I told him this person was no longer alive and was not a resident of this number. He was considerate and said the info would be recorded in their whatever and said sorry for the call.

    • I received a call from this number and 773-649-1832. Within minutes of eachother.  Both had the exact same recorded message.  They asked to speak to a person who doesn't live here..I name I've never heard before in fact.  i wanted to inform them that, that person does not live here. but i was not given an option to do that.  I pressed 9, the number you are supposed to press is you want to speak to a rep.  All I got was a busy signal after that. My guess: Debt Collectors
