In practice, yes: most wholesale suppliers ask for an EIN before they open an account. The IRS does not require every business to have one, but suppliers and state tax agencies use it to confirm you are a real business. The good news is that it is free and takes minutes to get.
Quick answer: You usually need an EIN to buy wholesale, because most suppliers ask for one on their application. You can get an EIN free from the IRS online in minutes. Never pay a third-party website for it.
What Is an EIN?
An EIN (Employer Identification Number) is a nine-digit federal tax ID for your business, issued by the IRS. Think of it as a Social Security number for your business. Banks, suppliers and state tax agencies use it to identify your business on accounts and paperwork.
Do You Need an EIN to Buy Wholesale?
The IRS only requires an EIN in certain cases. According to the IRS, you need one if, for example, you have employees, operate as a corporation or partnership, or file certain tax returns such as employment or excise returns.
But wholesale suppliers set their own rules, and most ask for an EIN because:
- it shows you are set up as a business, not buying for personal use
- it goes on your resale certificate and sales tax paperwork
- it lets them keep accurate records for their own tax reporting
So even if the IRS does not require one for your business, a supplier probably will.
How to Get an EIN for Amazon Wholesale
- Register your business first if you are forming an LLC or corporation. The IRS advises forming the entity with your state before applying.
- Go to the IRS website. Use the official Get an EIN page. The application is free.
- Have your details ready. You need the responsible party’s SSN or ITIN, your business name, address and structure.
- Complete it in one session. The online form times out after 15 minutes of inactivity, and it is only available during set hours.
- Save your confirmation. You get your EIN when you finish. Download the confirmation letter and keep it with your business documents.
Watch out: Some websites charge a fee to “file” your EIN application. The IRS says you never have to pay for an EIN.
Can I Use My SSN Instead of an EIN for a Wholesale Account?
Sometimes. A sole proprietor with no employees may not need an EIN for federal tax purposes and can use their SSN instead. Some suppliers accept that.
Many do not, though, and there is a good reason to get an EIN anyway: it keeps your Social Security number off supplier applications, invoices and resale certificates. Since it is free, most Amazon sellers simply get one.
Your business structure affects this choice. See do you need an LLC to sell wholesale on Amazon.
