You won't be able to lookup a
Seychelles company, you will have the
certificate of the company which has a number, this number is ofcourse registered somewhere but except this you won't be able to see any of the shareholders, directors or anything else about hte company, only that it is registered.
In the
Seychelles you can register a offshore company with bearer shares, which gives the highest layer of anonymity, however, you will get troubles to open a bank account if you don't have any really good connections, or you will need to give permission to the bank to know the beneficial owner of the company!
