What Is an EIN and Why Processors Ask for It
An EIN is a federal tax ID issued by the IRS to identify a business. Payment processors use it to:
-
Verify your business identity
-
Comply with KYC (Know Your Customer) and AML regulations
-
Report transactions to the IRS (Form 1099-K)
-
Reduce fraud and chargeback risk
In short: no EIN = higher risk, and many processors simply won’t approve the account.
Do You Need an EIN to Open a Merchant Account?
EIN is Required if you are:
-
An LLC (single-member or multi-member)
-
A Corporation (C-Corp or S-Corp)
-
A Partnership
-
A Nonprofit
-
A Foreign-owned U.S. business
-
Planning to process large volumes or recurring payments
EIN may be Optional if:
-
You are a sole proprietor with no employees
-
The processor allows SSN-based accounts (some do)
Even when optional, using an EIN is strongly recommended to protect your SSN and increase approval odds.
