Buying ammo online: age checks, shipping and state rules

Buying ammo online works a lot like buying anything else online, with a few extra checks. You confirm your age at checkout, the box ships by ground with special labeling, and depending on where you live, your state may add a permit check or require you to pick it up from a licensed vendor. This guide covers how each of those works, which rules come from federal law and which come from states, and how Price Dope fits in.

The short answer

• Yes, in most places. Federal law doesn't ban buying ammo online, and many retailers ship it to your door.
• The retailer checks your age. Federal law sets 18 for rifle and shotgun ammunition and 21 for other ammunition, such as handgun ammo, when you buy from a licensed dealer. Retailers can set stricter policies.
• It ships by private carrier, not the mail. The Postal Service doesn't carry ammunition, so retailers ship with private carriers, usually by ground, often with an adult signature.
• Some states add steps. California and New York route online ammo sales through a licensed vendor or dealer for an in-person handoff. Illinois, Connecticut, Massachusetts and New Jersey require a state card, license, permit or certificate for some or all ammunition purchases, and D.C. limits who may possess ammunition. Rules also vary by city and county.
• Price Dope doesn't sell ammo. We compare prices and link you to the retailer, which handles checkout, age checks and shipping.

Who checks what

When you buy ammo online, three parties are involved, and each has its own job:

1. The retailer sells the ammunition. It runs the checkout, verifies your age and, where required, your eligibility, and decides whether it can legally ship to your address.
2. The carrier delivers the package under its own published rules for ammunition, which can include ground-only service and an adult signature.
3. You are responsible for knowing whether you can legally buy and possess the ammunition where you live.

Price Dope isn't one of those parties. We don't sell anything, take payment, verify age or ship. When you click through to a deal, you finish the purchase on the retailer's site. See how Price Dope works and our affiliate disclosure for how links and commissions work.

Federal age rules

The main federal age rule is in 18 U.S.C. § 922(b)(1) and repeated in ATF's regulations at 27 CFR 478.99(b). A federally licensed importer, manufacturer, dealer or collector may not sell or deliver:

• any ammunition to someone under 18, and
• ammunition other than shotgun or rifle ammunition to someone under 21.

In practice, that's 18 for rifle and shotgun ammo and 21 for handgun ammo when you buy from a licensed dealer.

Two more federal points are worth knowing:

• Not every ammo seller holds a federal license. Federal law requires a license to manufacture or import ammunition, or to deal in firearms (18 U.S.C. § 922(a)(1)). A business that only sells ammunition may not hold one. Separately, federal law makes it unlawful for anyone to transfer ammunition that's suitable only for a handgun to a person under 18, with limited exceptions (18 U.S.C. § 922(x)).
• Some people can't legally have ammunition at all. The categories of people federal law bars from possessing firearms, such as those convicted of a felony, are also barred from possessing ammunition (18 U.S.C. § 922(g)). Lying to a licensed dealer to get ammunition is a federal crime (18 U.S.C. § 922(a)(6)).

States can set higher minimum ages, and retailers can choose stricter policies than the law requires. Some retailers sell all ammunition only to buyers 21 and older, which avoids having to sort calibers like .22 LR that work in both rifles and handguns. The checkout shows the retailer's rule.

How ammo ships

The Postal Service doesn't carry it

USPS Publication 52, the Postal Service's rulebook for hazardous mail, says small arms ammunition regulated as an explosive, along with primers, blank cartridges and propellant powder, is prohibited from mailing. That's why ammo retailers ship with private carriers, and why a standard PO box generally isn't an option for ammunition.

Private carriers ship it by ground

Federal hazardous materials rules let small arms cartridges ship as a limited quantity when they're packed in inner boxes, partitions or clips inside a strong outer box, with primers protected and a gross weight of 30 kg (66 lb) or less per package (49 CFR 173.63(b)). Each carrier then sets its own terms.

The two big private carriers publish their terms:

• UPS says it accepts ammunition that meets the federal definition of "cartridges, small arms," packed and labeled under the hazardous materials rules. Ammunition can't share a package with a firearm, and the shipper must follow all federal, state and local laws, including age restrictions. Limited-quantity ammunition moves only by UPS Ground within the 48 contiguous states, plus Ground service within Oahu and within Alaska.
• FedEx says in its Service Guide that it will transport ammunition when it's packed and labeled in compliance with local, state and federal law and with the guide's dangerous goods or hazardous materials rules for the FedEx service selected. Ammunition must ship separately as dangerous goods or hazardous materials, and shippers agree not to ship loaded firearms, or firearms with ammunition, in the same package. FedEx Home Delivery shipments can contain hazardous materials only if they're classified as limited quantity.

Because ammunition moves under hazardous materials rules, often by ground, ammo orders can take longer than other online orders. If you're in Alaska or Hawaii, check the retailer's shipping page before you order, because carrier options for ammunition can be narrower there.

Federal law also requires anyone who hands a package containing ammunition to a carrier for interstate shipment to a non-licensee to give the carrier written notice (18 U.S.C. § 922(e)). That notice is the retailer's job, not yours.

What's on the box

A limited-quantity package carries a diamond-shaped marking: a white center with black top and bottom points. You may still see older packaging that says ORM-D. The Department of Transportation phased that marking out in favor of the limited-quantity mark, and its guidance says packaging showing both marks still complies.

Adult signature

Many ammo retailers ship with adult signature required, so someone of age has to be there to sign. Carrier terms play a part too. FedEx's Service Guide, for example, says that when a product is age-restricted by law, the shipper must use its Adult Signature Required option, which needs a signer at least 21 with government-issued photo ID. Its ammunition passage doesn't add a separate signature rule. If you won't be home, check whether the carrier lets you pick up the package at one of its locations. Don't ask the retailer to drop the signature requirement. It's part of how the retailer meets its age-check obligations.

State and local rules

States and localities can add their own requirements on top of federal law. The examples below come from each state's statutes or official government pages. This list isn't complete. Other states have their own rules, cities and counties can add more, and these laws change and are sometimes challenged in court.

• California: Ammunition sales generally must be conducted by or processed through a licensed ammunition vendor. You can order online, but a licensed vendor has to receive the ammunition first and hand it over in person (Cal. Penal Code § 30312). Buyers must also pass a state eligibility check before each purchase, and the state's minimum ages are 18 for long gun ammunition and 21 for handgun ammunition (California DOJ, Ammunition Purchases FAQ). The background check requirement has been challenged in federal court in Rhode v. Bonta. The full Ninth Circuit is reviewing the case, and California DOJ continues to describe the checks as required (Ninth Circuit, pending en banc cases).
• New York: Ammunition sellers must register with the State Police and run each sale through a state background check. Commercial ammunition transfers must go through a licensed dealer or registered seller, and the handoff to the buyer must happen in person (N.Y. Penal Law § 400.03).
• Illinois: You generally need a Firearm Owner's Identification (FOID) card issued by the Illinois State Police to acquire or possess ammunition in the state, with limited exceptions (430 ILCS 65/2).
• Massachusetts: Buyers generally need a Massachusetts Firearm Identification (FID) card, which covers ammunition for rifles and shotguns that aren't large capacity or semi-automatic, or a License to Carry, which covers firearms including large capacity firearms and their ammunition (M.G.L. c.140 § 129B(c), § 131(a)). Massachusetts-licensed dealers must verify that license before transferring ammunition, and can't fill a mail, phone or internet order for ammunition unless the license is presented in person before the sale or delivery (M.G.L. c.140 § 123(f), (k)).
• New Jersey: To buy handgun ammunition, you generally must show a Firearms Purchaser Identification Card, a copy of a permit to purchase a handgun or a permit to carry a handgun, along with government-issued photo ID, and handgun ammunition may not be sold to anyone under 21. The law's definition of handgun ammunition includes ammunition that can be used in both rifles and handguns (N.J.S.A. 2C:58-3.3, as amended by P.L.2022, c.55).
• Connecticut: Sellers may not sell ammunition to anyone under 18, and buyers must show a pistol permit, an eligibility certificate or an ammunition certificate (with photo ID) (Conn. Gen. Stat. § 29-38m).
• District of Columbia: Generally, only people in listed categories, such as holders of a valid D.C. firearm registration certificate, may possess ammunition in the District (D.C. Code § 7-2506.01).

Rules like these are why a retailer may block your state at checkout, ask you to upload a state card or permit, or ship to a local licensed dealer instead of your door. To find your own state's rules, start with your state attorney general or state police website. Check city and county rules too.

What retailers check at checkout

Every retailer runs its own process, but these are the common steps:

• Age verification. You confirm your date of birth, and some retailers check your name and address against an identity verification service or ask you to upload an ID.
• Restricted-location blocks. Retailers block shipping to states, cities or ZIP codes where they can't legally deliver an item, or where their own policy says no.
• State documents. Where a state requires one, the retailer may ask for a copy of a state license, card or permit before it ships.
• Ship-to-dealer. Where direct shipping isn't allowed, some retailers ship to a licensed local vendor or dealer for pickup. The receiving business may charge a fee, so call ahead.
• Adult signature on delivery.

If a retailer cancels or holds your order over one of these checks, contact the retailer. Price Dope can't see or change your order.

How Price Dope fits in

Price Dope is a price-comparison search engine for firearms and ammo. We show offers from connected retailers, rank ammo by cost per round, show when each price was last checked, and keep D.O.P.E. price history on product pages. We don't sell anything, and we don't verify age, eligibility or shipping. Those happen on the retailer's site, under the retailer's policies and the law.

Shipping-restriction notices on product pages

Some product pages show a Shipping restrictions line at the bottom of the price box. Here's exactly what it is:

• Where it comes from: the product data we receive for that item. When the data lists places the item isn't sold to or can't be shipped directly to, we show them. If the data doesn't list any, there's no line.
• What it says: "not sold to" followed by state or territory codes, "no direct ship to" followed by codes, or both. Occasionally it names a city, and it may carry a short qualifier copied from the listing.
• What "no direct ship" means: the item can't ship to your door there and ships to a local dealer instead.
• More detail: hover over the line to see full state and territory names.

What it isn't:

• It isn't based on your location. Everyone sees the same notice for a product.
• It isn't each retailer's policy. A retailer can have stricter rules, or a different list, so its checkout has the final word.
• It isn't a legal determination, and no notice doesn't mean an item can ship to you.

The notice appears on product pages only, not in the live price tables on caliber pages or in posts like this one. Treat it as an early heads-up, then confirm at checkout.

Before you order: a checklist

1. Check your state and local rules for buying and possessing ammunition, including any license, card or permit you need.
2. Check the retailer's shipping and age policy before you build a cart. Most retailers list restricted states and their minimum age on a shipping or FAQ page.
3. Look for a shipping-restriction notice on the Price Dope product page, then confirm at the retailer's checkout.
4. Use a street address where an adult can sign, or plan a carrier pickup.
5. Compare the delivered price. Cost per round uses the listed price, so add shipping, tax and any fees to compare retailers fairly. More in cost per round, explained.
6. Check the price history. Product pages show D.O.P.E. price history, so you can tell a real drop from a normal price. See how D.O.P.E. price history works.

Compare prices before you buy

Once you know you can order, the rest is finding a good price. These tables update from connected retailers and show in-stock offers, cheapest per round first, each with when its price was last checked. Cost per round doesn't include shipping, tax or fees. Browse every caliber on the ammo page, or see the cheapest offers side by side on Deals.

Buying ammo online FAQ

Can you buy ammo online?

In most of the U.S., yes. Federal law doesn't ban buying ammunition online, and many retailers ship it to your door. The retailer checks your age at checkout, and it won't ship to places where the sale isn't allowed. Some states add their own steps. California and New York, for example, require online ammo orders to go through a licensed vendor or dealer and be handed over in person, and other states require a state license or certificate to buy. Check your federal, state and local law before you order.

How old do you have to be to buy ammo online?

Under federal law, a licensed dealer can't sell rifle or shotgun ammunition to anyone under 18, or any other ammunition, such as handgun ammo, to anyone under 21 (18 U.S.C. 922(b)(1)). Federal law also bars anyone from transferring ammunition that's suitable only for handguns to a person under 18 (18 U.S.C. 922(x)). Some states set their own minimums, and some retailers require buyers to be 21 for all ammunition. The retailer's checkout tells you its policy.

Can ammo be shipped to your house?

Often, yes, where state and local law allow it. Retailers ship ammunition with private carriers, and many require an adult signature at delivery. Some states don't allow direct-to-home delivery. In California, an online ammo purchase has to be received and processed by a licensed ammunition vendor first, and in New York the transfer has to happen in person through a licensed dealer or registered seller.

Can you ship ammo with USPS?

No. USPS Publication 52 says small arms ammunition regulated as an explosive is prohibited from the mail, along with primers and propellant powder. Retailers use private carriers instead, which publish their own rules for ammunition.

Can I have ammo shipped to a PO box?

Generally not. A standard PO box is served by the Postal Service, and the Postal Service doesn't accept ammunition, so expect the retailer to ask for a street address. California's Department of Justice also says a P.O. box isn't acceptable as the purchaser's address for an ammunition purchase there.

Does Price Dope sell ammo or verify my age?

No. Price Dope compares prices and links you to retailers. You buy from the retailer, and the retailer handles checkout, age and eligibility checks, and shipping.

What does "Shipping restrictions" mean on a Price Dope product page?

When the product data we receive lists places the item can't be sold or shipped directly to, the product page shows a Shipping restrictions line under the price box, such as "not sold to" or "no direct ship to" followed by state or territory codes, and occasionally a city. Hover over it to see the full names. "No direct ship" means the item ships to a local dealer instead of your door. The notice comes from the product data, not your location or each retailer's own policy, and no notice doesn't mean an item can ship to you.

Does cost per round include shipping and tax?

No. On Price Dope, cost per round is the listed price divided by the number of rounds. Shipping, taxes, fees and coupons are set by the retailer and may not be included, so check the final price at checkout.

Prices shown come from connected retailers' latest checks and change often. Price Dope doesn't sell anything and may earn a commission from retailer links. Disclosure · How we collect prices · Editorial standards
