Re: How does craigslist know I am using a VoIP service???? My T-Mobile prepaid says OK, GrandCentral voip and IPKall voip.
They probably lookup who owns the NPA NXX X number block in a database like www.localcallingguide.com. If it is Level3 or somone suspect they reject it.

| My verizon landline number ported to voipo comes up as fixed too, so I think you may be right. |

I do know that current carrier info is contained in some databases. There was a while when the Nextel website would let you do an LNP check that gave the current carrier (not the carrier of the NPANXX block). |

There was a while when the Nextel website would let you do an LNP check that gave the current carrier (not the carrier of the NPANXX block). I just tried my cellphone number that I ported from a land line 3 years ago, and it came up "Fixed Line." I think the "ReduceFraud.com" guys are simply charging for NPA NXX lookups! (Nice work if you can get it!)  |
