Anyone can share a shell office in the US with a real person secretary. Depending on incoming line, she will respond with either "Faked Corp", "NoNameInc", "MyShellCompany" etc and transfer your phone to a recording machine. And don't bother with ERAI members either, they don't know jack what's the differences between an IC chip and a potato chip. There are plenty of articles about ERAI members being nailed by selling counterfeit chips in the US.
Words of mouth from those doing business overseas that you know personally are more credible than random recommendations from strangers from any website, this one included.
How do I know? I have tested thousands of various ICs sold from China for many customers to know that your chance to be screwed is around 99.1%. Now if you have to buy from someone from overseas (the US included), insist to have the right to return if the parts are found to be counterfeited (or not working according to spec). That definitely helps to weed out the wrong ones.
