Hello stellar! Please try to calm down and I`ll try to explain Taxpayer Identification Numbers (TIN).
The two most common types of Taxpayer Identification Numbers are Social Security Numbers (SSN) and Employer Identification Numbers (EIN).
SSNs should be kept as confidential as possible; obviously you will need to disclose this number to some entities such as your employer, the IRS and a bank if you were to obtain a loan or credit card.
EINs in and of themselves cannot be used to obtain credit. These are issued to "Employers" (i.e. Businesses) and in order for businesses to obtain financing they must disclose much more information than just their EIN.
Businesses must disclose this number for various reasons such as to some customers/clients who may need to issue them a 1099.
I hope this helps to calm you down until someone else posts.
