“No purchase necessary” laws, explained

Last reviewed September 2026 · researched from primary sources. Not legal or tax advice — see our Disclaimer.

You see it on every soda cap, fast-food game and online giveaway: no purchase necessary, a purchase will not increase your chances of winning. It is there because of one rule of U.S. law — a prize promotion that requires payment and picks winners at random is an illegal lottery. Removing the payment requirement is what keeps a sweepstakes legal.

The rule behind the phrase

A lottery has three parts: a prize, a winner chosen by chance, and consideration (the entrant gives up something of value to enter). Private lotteries are reserved to state governments, so a business that runs one is breaking the law. A sweepstakes keeps the prize and the chance but strips out the consideration — entry must be free. The “no purchase necessary” line is the sponsor telling regulators, and you, that they have done so.

The free entry has to be a real one

It is not enough to bury a free route in the fine print. Sweepstakes law and FTC guidance require the free method of entry to be given equal dignity: the same chance of winning as any paid or purchase-linked entry, and roughly equal prominence in the advertising. If a promotion pushes “buy to enter” and hides the free option, that is a legal problem for the sponsor.

What the free route usually looks like

• Mail-in. Hand-print your details on a 3×5 card and mail it — still the classic alternate method of entry (AMOE).
• Online form. A web page where you enter without buying anything.
• In-app action. A free daily tap, spin or check-in that awards entries.

Each of these counts as one entry with the same odds as a code from a purchased product.

What a sponsor can and cannot ask for

Sponsors can ask you to give an email address, watch a short video, answer a question or follow an account — those are generally not treated as “consideration.” They cannot require a purchase, a payment, or (in stricter states) a substantial effort like attending a sales presentation, as the only way in.

“Void where prohibited”

Its companion phrase. Promotion rules vary by state, and a few (historically Rhode Island, Florida and New York for larger prizes) add registration or bonding requirements. Rather than tailor a promotion to 50 rulebooks, sponsors write to the strictest standard and declare the offer void anywhere it would not comply.

What this means if you are entering

• You never have to spend money to enter a legitimate sweepstakes, or to claim a prize you have won.
• Using the free entry method does not lower your odds — by law it cannot.
• If a “winner notification” asks you to pay a fee, taxes up front, or “shipping and handling” to release a prize, it is a scam. Real sponsors handle taxes through a 1099, not an upfront charge.

Why raffles are the exception

A raffle looks like a sweepstakes and breaks the rule openly: you buy a ticket, tickets are drawn at random, someone wins. That is prize plus chance plus payment — the textbook definition of a lottery. Raffles are lawful only because states carve out a narrow exception for them, and the conditions are strict: in most states only a registered nonprofit may run one, often with a permit, a cap on prize value, and rules about how the proceeds are used. A few states do not allow charitable raffles at all.

So if a for-profit business sells tickets for a random draw and calls it a raffle, it is not using a loophole — it is running an illegal lottery. The same promotion becomes lawful the moment tickets are free, which is precisely the adjustment “no purchase necessary” describes.

How to spot a promotion that is breaking the rule

Most sponsors get this right because the penalties are real. The ones that do not tend to share a few traits:

• No free entry route at all where a purchase clearly improves your position.
• A free route that is deliberately painful — a mail-in address buried in a PDF, a handwritten card required per entry, or a limit on free entries that does not apply to paid ones.
• Language implying paid entries do better, such as “more entries with every purchase” without an equivalent free route.
• No official rules published anywhere, or rules with no named sponsor.
• A fee to claim a prize you have supposedly already won — always a scam, never a compliance mistake.

The first four are usually sloppy marketing rather than fraud. The last one is different in kind: see the warning signs of a sweepstakes scam.

Frequently asked questions

What does “no purchase necessary” actually mean?

That you can enter and win without spending anything. It is not a courtesy — removing payment is what stops the promotion from being an illegal private lottery, so the sponsor has to mean it.

Are all giveaways no purchase necessary?

Every random-draw giveaway has to be. A skill contest — where entries are judged rather than drawn — can legally charge an entry fee in most states, because chance is not what picks the winner.

Does the free entry have worse odds than a paid one?

No, and that is the point. The “equal dignity” principle requires the free route to carry the same chance of winning as any purchase-linked route. A sponsor that weights the paid entries has broken the rule.

Why do contests say no purchase necessary if they are skill-based?

Caution. State law on what counts as a skill contest, and on entry fees, varies enough that national promotions are usually written to the strictest interpretation rather than risk being treated as a lottery somewhere.

Is a “no purchase necessary” giveaway legit?

The phrase alone proves nothing — scammers copy it. What tells you is whether official rules exist, name a real sponsor, disclose prize values, and give a workable free entry route. And whether anyone asks you for money, which a genuine sponsor never will.

Can a raffle say no purchase necessary?

A raffle normally charges for tickets, which is why it is restricted to licensed nonprofits in most states. If a promotion calls itself a raffle but is free to enter, it is functionally a sweepstakes.
