基本信息了），哪里可以得到？看到很多网站有这种数据，不知道他们从哪里弄来的。

发帖数: 2172 | 2 These are yellowpage type of listing data. There are many providers.
Originally, these data comes from the business bureau of each state. But a
few major players hired a few hundred people to verify these data every few
month. There are around 5 major players, www.databyacxiom.com, www.infousa.
com, www.dnb.com, etc. None of these provides 100% accurate information. You
can expect accuracy up to 90%. Smaller players are normally resellers, most
of them are illegal.
