Yes, you can buy ammo online in most of the United States. Federal law treats an online ammunition purchase the same as one made over a retail counter: it looks at who you are, not where the transaction happens. The complications come from two places. Your state may require a permit, a background check, or shipment through a licensed dealer, and a handful of states block direct-to-home delivery entirely. On top of that, ammunition is a regulated hazardous material, so it ships only by ground through private carriers and carries a surcharge that can quietly reshape the price.
Who Can Legally Buy Ammunition
Federal eligibility rests on 18 U.S.C. § 922. A licensed dealer cannot sell rifle or shotgun ammunition to anyone under 18, or handgun ammunition to anyone under 21.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Federal law does not, however, dictate how online sellers verify age. Many rely on a checkbox at checkout. Some ask for an ID upload as a matter of company policy, not federal requirement.
The same statute lists categories of people who cannot legally possess ammunition at all. You fall into a prohibited group if you have been convicted of a crime punishable by more than a year in prison, are a fugitive from justice, use a controlled substance, have been adjudicated mentally defective or committed to a mental institution, are unlawfully in the United States or hold most nonimmigrant visas, were dishonorably discharged from the military, renounced your U.S. citizenship, are subject to a qualifying domestic protective order, or were convicted of a misdemeanor crime of domestic violence.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
One trap catches people who assume state law protects them. Federal law still classifies marijuana as a controlled substance, so anyone who uses it, including medical cardholders in states where cannabis is legal, is a federally prohibited person for ammunition purposes. The ATF has reinforced this position, and courts have upheld it.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
Armor-piercing ammunition is off the table entirely for civilian buyers under 18 U.S.C. § 922(a)(7) and (a)(8), which reserve it for government agencies, exporters, and entities authorized by the Attorney General for testing.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Some states also restrict specialty rounds like tracers.
Whether Your State Allows It
State law is where a straightforward online order can fall apart. Restrictions come in two main forms.
Background Checks and Permit Requirements
A small but growing group of states requires screening before you can buy ammunition. A few run a point-of-sale background check similar to a firearm purchase. Several others require you to hold a state-issued permit or identification card, such as a Firearm Owner’s Identification card. Altogether, roughly half a dozen states impose one of these requirements. If you live in one of them, most online retailers will either ask you to upload the permit at checkout or refuse to ship to your address.
Direct Shipment Bans
Other states prohibit retailers from shipping ammunition directly to your home. Orders instead go to a licensed dealer or ammunition vendor, where you pick them up in person, sometimes after a background check. Some states do not ban direct shipment outright but are effectively cut off because major distributors will not deal with their regulatory overhead. At present, roughly a dozen states and the District of Columbia have restrictions strict enough that most online retailers will not ship ammunition to a residential address there. Every retailer publishes a shipping policy page; check yours for your specific state before you place an order.
How the Ammunition Reaches You
Ammunition is classified as a Division 1.4S explosive under Department of Transportation rules, and that classification governs how it moves.
The U.S. Postal Service prohibits mailing small arms ammunition entirely, domestic or international, and sending it through the mail is illegal under federal law.3United States Postal Inspection Service. Prohibited, Restricted, and Non-Mailable Items All online ammunition shipments move through private carriers such as UPS and FedEx.
Shipments almost always travel by ground. When packaged as Limited Quantity material under DOT rules, carriers like FedEx restrict ammunition to ground service within the contiguous 48 states.4FedEx. Hazardous Materials FedEx Ground Shipping Guide That means longer transit times than typical online orders, and buyers in Alaska and Hawaii face additional hurdles because ground service is not available and hazmat air restrictions apply. Some carriers also require an adult signature at delivery.
What It Actually Costs
The per-round price you see on a retailer’s site is rarely the price you pay.
Because ammunition is hazardous material, carriers add a per-package surcharge on top of base shipping. UPS charges around $33 per package for ground hazmat shipments, and most online retailers pass this fee to you at checkout, either as a line item or bundled into a flat shipping charge. The surcharge is per package, not per round, so a single large order costs the same in hazmat fees as a small one. Bulk orders spread that fixed cost across more ammunition.
An 11% federal excise tax applies to shells and cartridges under the Pittman-Robertson Wildlife Restoration Act.5Office of the Law Revision Counsel. 26 USC 4181 – Imposition of Tax Manufacturers pay it and build it into wholesale prices, so you will not see it as a separate checkout charge, but it is part of why ammunition costs more than the raw materials suggest.
If your state requires shipment through a licensed dealer, that dealer typically charges a transfer fee for receiving the package and handing it to you. These fees generally run from $10 to $45 per transaction. Add that to your comparison when you weigh online prices against a local shelf.
Penalties for Buying When You Cannot
Federal penalties are serious. A prohibited person caught possessing ammunition faces up to 15 years in federal prison, a ceiling that rose from 10 years under the Bipartisan Safer Communities Act in 2022.6Office of the Law Revision Counsel. 18 USC 924 – Penalties Three or more prior felony convictions for violent crimes or drug trafficking trigger a mandatory minimum of 15 years with no possibility of parole.7U.S. Department of Justice. Quick Reference to Federal Firearms Laws
The federal straw purchase statute at 18 U.S.C. § 932 covers firearms specifically, not ammunition, but buying ammunition for a prohibited person can still bring charges under other federal provisions, including aiding and abetting.8Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms State penalties vary and range from misdemeanor fines to felony charges and loss of firearm rights.
Placing the Order
Once you know you are eligible and your state allows delivery, the process is straightforward. Start on the retailer’s shipping policy page and confirm your state is not on the restricted list. Some sites flag the restriction automatically when you enter your zip code.
Know your firearm’s exact caliber and cartridge type before you add anything to your cart. Ammunition is not interchangeable, and firing the wrong cartridge can destroy a gun or cause serious injury. The caliber is stamped on the barrel or slide and printed in the owner’s manual. Ask a local dealer to confirm if you are unsure.
At checkout you will confirm your age, usually through a checkbox and occasionally by uploading a government-issued ID. If your state requires a permit or identification card, the retailer will ask you to upload a copy. If your state requires dealer-to-dealer shipment, the checkout will prompt you to pick a participating FFL near you.
Order in bulk when you can. The hazmat surcharge is fixed per package, so consolidating one large order spreads the cost, and many retailers waive or reduce base shipping above a threshold, which further offsets the fee.
