What Documents Do You Need to Open a Wholesale Account? A Step-by-Step Guide for Amazon FBA Sellers
If you’re an Amazon FBA or FBM seller looking to source products at wholesale prices, one of the biggest hurdles isn’t finding suppliers — it’s getting approved by them. Most legitimate wholesale suppliers won’t sell to just anyone off the street, and that’s actually a good thing. It means the supplier is operating a real, compliant business rather than running an unverified drop-ship scheme.
If you’ve been turned away or ignored by a supplier and aren’t sure why, this guide breaks down exactly what documentation you need to have ready — and why suppliers ask for it in the first place. Why Wholesale Suppliers Require Documentation Wholesale suppliers sell in bulk at reduced prices, which means they’re extending real financial trust to every buyer they approve. Requiring documentation protects the supplier from:
Reselling to buyers who aren’t operating a legitimate business
Running afoul of manufacturer distribution agreements
Tax and compliance issues tied to resale transactions For you as a buyer, going through this process is also a signal of legitimacy — it separates real wholesale relationships from unreliable “gray market” sourcing. The Core Documents You’ll Need
EIN (Employer Identification Number)
Your EIN is the IRS-issued number that identifies your business for tax purposes. Suppliers use it to confirm you’re operating as a registered business entity, not an individual reselling casually. If you’re a sole proprietor without an EIN, you can apply for one for free directly through the IRS website — it typically takes minutes.
Seller’s Permit (Resale Certificate) Also called a resale certificate in many states, this document allows you to purchase goods tax-free for the purpose of reselling them. Suppliers require this both to remain compliant with state tax law and to confirm you’re a legitimate retailer. Requirements vary by state, so check with your state’s Department of Revenue if you don’t already have one.
Business Formation Documents (Sometimes Requested) Depending on the supplier, you may also be asked for your Articles of Incorporation, LLC formation certificate, or a copy of your business license.
This is less universal than the EIN and seller’s permit but worth having on hand.
Amazon Seller Account Details Many wholesale suppliers working specifically with Amazon FBA sellers will ask for your storefront link or seller account information, partly to verify you have an active selling account and partly to understand your sales volume and category focus.
How the Approval Process Typically Works
Submit your application along with your EIN and seller’s permit.
Supplier review — the supplier verifies your documents match your business name and that your permit is valid and current.
Account approval — once verified, your wholesale account is opened.
Catalog access — you’ll typically receive access to the full wholesale product catalog and pricing. The turnaround time depends on the supplier, but having your documents ready and accurate from the start is the single biggest thing you can do to speed up approval. Common Mistakes That Slow Down Approval
Business name mismatches — your EIN, seller’s permit, and application should all list the same legal business name.
Expired or missing permits — some states require permits to be renewed periodically.
Incomplete applications — missing a document usually means starting the review over.
