Find what carrier hosts a phone number



  • I found this site that tells you what carrier a phone number belongs to.

    Huh, doesn't look good.



  • @Dashrender Are you trying to find the Service Provider or the data in LERG? A good way to think of that is are you trying to find who is the Domain Registrar or who is the DNS Service Provider?

    If you have a particular number in mind, and want to see which service provider (like Skyetel, Voip.MS, Flowroute, etc) thats different than seeing what is in LERG.

    Actually - when I first saw that - I assumed it was a script error and didn't actually read it. Now on second glance, I see there is useful information in there.

    Personally - I want to know the Carrier - Cox, AT&T, Verizon, Skyetel, etc... that is what I got from the link I posted.

    I see in the picture that the number I put in mentions WindStream - but the site I used says Alltel

    The difference between Alltel and WindStream is the equivalent difference between Godaddy and DNSMadeEasy. WindStream is the "Name Server" and Alltel is the "DNS Provider." They will usually be different from each other for most carriers, but sometimes they match up. It depends on the phone number and the carriers coverage and network. This is also true for VoIP numbers that have SMS enabled - those will return different results too.

    I can go into further detail if you need - but the end user's relationship is almost always with Alltel and not Windstream. If you are looking for who the customer has a relationship with, then thats a lot harder (its usually confidential). But which LEC is in the LERG or has the LRN is public information if you know where to look 🙂

    I did want to know who the customer had a relationship with- mainly to see if that one carrier was having an issue, or if there was a systemic issue in the phone fabric.

    Cox claimed that their outage yesterday was basically the equivalent of a BGP issue - The central router that routes numbers crashed so calls couldn't be routed. I suppose I could be mistaken on my comparison to BGP..

    As I mentioned, the site in the OP did tell me the "who the client has a relationship with" which is what I wanted to know.
    Why would that information be confidential?

    Cox is an example of a carrier where the "Registrar" is same company as the "DNS Provider" to keep torturing my analogy. So thats why it showed up. There's a bunch fo databases for phone numbering - so depending on where you look you may see different information. Its all accurate, its just used for different things.

    It's not always confidential, it just depends on the carriers CPNI and Privacy Policy. Its confidential for us - we don't share who our customers are without a court order. Some carriers are less worried about it.



  • Awsome, I shared it on Twitter!
