How It Works
From Search to Doorstep,
Every Step Verified
Whether you're fixing your daily driver or sourcing inventory as a vendor, here's exactly how GenuineAutoPartsUSA works.
For Buyers
Get the Right Part, Fast
Find Your Part
Select your Year/Make/Model/Trim for exact fitment, or search by part name or number. Every listing shows verified compatibility data before you buy — no guessing, no returns for wrong fitment.
Compare & Order
Filter by brand, condition, and price. Every listing is clearly labeled OEM, Aftermarket, or Remanufactured, so you always know exactly what you're getting. Checkout is secured through Stripe.
Fast, Tracked Shipping
Most orders ship the same day they're placed. You'll get real-time tracking from dispatch to your door, straight from the vendor who packed it.
30-Day Returns
If a part doesn't fit or isn't what you expected, you have 30 days to return it — no runaround, no restocking-fee surprises.
For Vendors
List Parts, Reach Buyers, Get Paid
Apply & Get Verified
We confirm business registration, EIN, and state licensing before any vendor can list a single part. It typically takes 2-3 business days.
List Your Inventory
Upload your catalog with accurate part numbers, fitment data, and condition (OEM / Aftermarket / Reman). Our team audits new catalogs for accuracy.
Connect Payouts
Set up Stripe Connect in minutes. Payouts go directly to your bank account on a rolling schedule — no waiting on a marketplace to cut a check.
Sell & Grow
Reach buyers actively searching for their exact vehicle fitment. AI-assisted fraud scoring and buyer feedback loops keep the marketplace healthy for everyone.
Common Questions
How do I know a part will fit my vehicle?
Every listing includes a fitment table verified against Year/Make/Model/Trim/Engine data (cross-checked with NHTSA vehicle records). If you select your vehicle before searching, we only show parts confirmed to fit.
What's the difference between OEM, Aftermarket, and Remanufactured?
OEM parts are genuine manufacturer parts. Aftermarket parts are new parts made by third-party brands to meet or exceed OEM specs. Remanufactured parts are professionally rebuilt to OEM standards using inspected cores. Every listing states its condition clearly.
How fast is shipping?
Most vendors ship the same day an order is placed. Exact delivery windows depend on the vendor's location and your shipping address, and are shown at checkout before you pay.
What if the part doesn't fit or arrives damaged?
You have 30 days to return it for a refund or exchange. Start a return from your order history — no need to call the vendor directly.
How are vendors vetted?
Every vendor goes through business verification, an initial inventory audit, and ongoing quality monitoring. Vendors with repeated accuracy or fulfillment issues are suspended.
