Hey Robert G.
I'm a clip producer and have been sold on Clips4Sale.com for a few years, along with a few other clip sale sites. C4S is by far my favorite and my highest earning site. Now on to your question, ANY reputable site (or job) will ask for your personal information including your SS#. If your worried about giving it out you can sign up for an EIN (if your in the USA) and have income sent as a check to your home if you'd rather not give deposit information. Personally I enjoy getting my direct deposit on the 7th each month. C4S will also send you a 1099 and you are expected to pay taxes on your income. Good luck with your studio.

We have over 100,000 studios on our website run by people from around the world. All information is private and confidential. You can not open an account without the information because if you are in the US we have to send you tax documents and if you wish to get paid via ACH or Wire we need your bank details: http://clips4sale.com/list/en/page/openastudio
