Online Firearms Sales: FFL Compliance for eCommerce

The Legal Framework for Online Firearms Sales

There is no federal law prohibiting the online sale of firearms. What federal law requires is that every retail firearms transfer — regardless of how the sale was initiated — must be completed through a licensed dealer with a 4473 and background check. The internet is a sales channel, not a transfer mechanism.

This means online firearms sales follow a consistent pattern: the buyer purchases online, the firearm is shipped to an FFL near the buyer (either your own location or a receiving dealer), and the buyer completes the 4473 and background check at the receiving dealer's premises before taking possession. No firearm ever ships directly to an individual consumer.

Platforms like GunBroker, Guns.com, and your own eCommerce site are all legitimate channels. The compliance requirements are the same regardless of where the sale originates.

Interstate FFL-to-FFL Transfers

When you sell a firearm online to a buyer in another state, the firearm must be shipped to a licensed dealer in the buyer's state. You cannot ship directly to the buyer. The receiving dealer completes the 4473, runs the background check, and processes the transfer under their license — following both federal and their state's requirements.

Before shipping, verify the receiving dealer's FFL. Request a copy of their license and confirm it's valid and unexpired. You can verify FFL status through the ATF's EZ Check system. Ship only to the address on the receiving dealer's license — not to a PO box, home address, or alternate location.

Log the shipment in your bound book as a disposition to the receiving dealer's FFL. The receiving dealer logs it as an acquisition from your FFL. The paper trail must be complete on both ends.

Intrastate Online Sales

If the buyer is in your state, you can ship the firearm to your own store for the buyer to pick up, or you can complete the transfer at your premises if the buyer visits in person. The 4473 and background check still apply — online payment does not constitute a completed transfer.

Some states with universal background check laws require all private online sales to go through a dealer even for intrastate transactions. In those states, every online sale between private parties — whether on GunBroker, Armslist, or social media — must be processed through an FFL.

Marketplace-Specific Requirements

Online firearms marketplaces impose their own compliance requirements on top of federal and state law. GunBroker requires all transfers to go through a licensed FFL and verifies dealer licenses in their system. Other platforms have similar policies.

When listing firearms online, ensure your product descriptions comply with both the platform's terms of service and applicable advertising laws. Do not list firearms that are prohibited in the buyer's state — some platforms allow filtering by state, while others place the compliance burden on the seller.

Shipping restricted items (such as magazines exceeding state capacity limits or firearms banned in certain states) to a receiving dealer in a restricted state creates compliance risk for both you and the receiving dealer. Know your buyer's state laws before shipping.

State-Specific eCommerce Restrictions

Several states impose restrictions on online firearms sales that go beyond the federal framework. Some states prohibit the sale of firearms through internet-based classified advertising to private parties. Others require additional waiting periods that affect when a receiving dealer can release the firearm. States with assault weapons bans prohibit the sale or delivery of banned firearms within their borders.

Before building your online sales operation, map the state-specific restrictions that affect your target markets. If you sell nationally, you need to know the rules in all 50 states — or at minimum, the states where you generate the most online sales volume.

4473 Procedures for Online Orders

The 4473 is always completed at the point of transfer — the receiving dealer's premises — not at the point of sale. If you're the receiving dealer, you complete the 4473 when the buyer arrives to pick up the firearm, not when the order is placed online.

If the buyer's background check is denied at the receiving dealer, the firearm is not transferred. The receiving dealer contacts you to arrange return shipment. You log the return in your bound book as an acquisition from the receiving dealer. The buyer receives a refund per your sales policy.

This is why clear return/refund policies for denied background checks are essential for online firearms sales. Communicate this upfront — before the buyer completes payment — to avoid disputes.

Recordkeeping for Online Sales

Your bound book must reflect every online sale. Log the disposition to the receiving dealer's FFL when you ship the firearm. Retain copies of the receiving dealer's FFL license, your shipping documentation, and any correspondence related to the transfer.

Bravo's eCommerce integration connects your online sales directly to your POS and compliance systems — so when a firearm sells online, the bound book entry, shipping documentation, and receiving dealer records are all managed in one place.
