If you have a judgment against a business it is helpful to know the federal taxpayer identification number (TIN) for the business. This is important when you are attempting to garnish a business bank account. To search for a TIN, we must have the complete name of the business, the address of the business and the owner's or CEO's full name and social security number. We offer two prices for this service depending on whether or not you know the owner/CEO social security number.
