How StampSwap Works
List an item in under 5 minutes. Find what you want in seconds. Complete the transfer with step-by-step guidance.
Step 1: List or Browse
Create a listing with photos, specs, and your asking price — or browse existing listings filtered by type, caliber, manufacturer, price, and location.
Step 2: Connect & Negotiate
Message sellers, make offers, and agree on terms — all through our secure in-app messaging system. Save listings to your watchlist and set up saved searches with email alerts so you never miss a deal.
Step 3: Prepare the Transfer
Use our Form 4 guide to prepare all required documents and paperwork. Our state compliance checker ensures the transfer is legal in your jurisdiction. For interstate transfers, find a licensed FFL/SOT near you through our dealer directory.
Step 4: Exchange Documents Securely
Upload and share transfer paperwork — photos, fingerprints, government ID, trust documents, and bills of sale — through our encrypted data room. Both parties can access documents without exchanging personal email or phone numbers.
Step 5: Complete & Review
Track the ATF approval process from Form 4 filed through ATF approval to item transferred. Once complete, leave a review to build your reputation for future transactions.
