Can someone please help verify the legitimacy of this company in Bangkok? Someone overseas wants to place a huge order but I am very suspicious the company may not be legitimate.

From the address provided that company is not in Bangkok.

When I look online I find two addresses for this company, neither of which are the address you supplied.

 

You need to ask the company for a copy of their "DBD" company document. If we have that then we can advise you further.

 

This document is something all companies have, and they will find our multiple copies each year. They should be able to send you either a scan or photos of their DBD very quickly.
