No purchase necessary: why sweepstakes offer a free way to enter
General information, not legal advice.
Nearly every giveaway ad carries the words "no purchase necessary" somewhere in the fine print. Those three words are the reason the promotion can run at all in the US. They also mean you can enter without buying anything, even when the ad shows nothing but a Buy button.
This page explains where that rule comes from, what a free route looks like, and how a free sweepstakes differs from a lottery or a raffle.
A lottery has three elements
In the US, a lottery is generally defined by three elements: a prize, chance and consideration. A prize is anything of value. Chance means the winner is picked at random and not by skill. Consideration usually means something paid or given up to take part, and the plain example is money.
If all three are present, the promotion is a lottery, and private lotteries are generally illegal. State governments run their own, and some states allow narrow exceptions for groups like charities. A truck dealer or a T-shirt company doesn't get that exception.
A sponsor who wants to give away a truck can't do much about the prize, and picking a name at random is the whole appeal, so chance stays too. That leaves consideration. Remove it and the promotion is no longer a lottery.
How a free route removes consideration
The way to remove consideration is to let people enter without paying. That free route is called an alternate method of entry, or AMOE. If anyone can enter for free, then a purchase isn't required to take part, and the promotion can operate as a sweepstakes. A sponsor can still sell products that come with entries, as long as the free route is real.
That's why the line appears so often. It usually reads "no purchase necessary" and often adds "a purchase will not increase your chances" in promotions where entries aren't sold. Merch-backed giveaways use different wording, because buyers there do get more entries. The exact language varies by sponsor and state, and the details are for the sponsor's lawyers.
Sweepstakes vs lottery
The practical difference in sweepstakes vs lottery is the free route. Both pick a winner by chance. A lottery charges every player. A sweepstakes must leave a door open for people who pay nothing.
Skill contests are a separate category. A photo contest or a recipe contest is judged, so there's no chance element, and the rules for those work differently. If a promotion says the winner is picked in a random drawing, it's a chance promotion, and the free route matters.
Sweepstakes vs raffle
People use these words as if they mean the same thing, but they don't. In the comparison of sweepstakes vs raffle, the raffle is the one that requires a paid ticket. It's a form of lottery, so it's generally legal only for groups the state allows, such as registered nonprofits, and only under that state's conditions.
A sweepstakes has a free way in. Some giveaways with a charity partner are built as sweepstakes for this reason, and offer a free entry alongside donations. If there's no free way to enter, we don't list it. You won't find raffles on FreeEntry.
What a free entry looks like
The AMOE takes a few common forms, and the official rules say which one applies:
- Mail-in entry. A hand-written card with your details, sent to an address in the rules. This is the most common free route on merch-backed giveaways. Our mail-in guide goes through it step by step.
- Online form. A free entry form on the sponsor's site, with no payment step. Many brand promotions work this way.
- Free code request. When entries normally come from a package code, the rules may let you request a code by mail.
Are free and paid entries equal?
Each entry generally has to be treated equally in the drawing. A free entry goes in the same pool as a paid one and has the same chance of being picked as any other single entry.
That is different from saying a free request gets you the same number of entries as a purchase. The number of entries per request varies by sponsor. One card may earn a single entry at one giveaway and hundreds at another, and in both cases a buyer may hold thousands. Your chance depends on how many of the entries in the pool are yours. What's the catch? walks through that math.
Why the free route is hard to find
Sponsors have to offer a free route, but they have no reason to promote it. A giveaway that makes money from merch puts its sales pages up front and leaves the AMOE in the official rules, usually in a link at the bottom of the page. Ads rarely mention it.
That's the gap FreeEntry exists to fill. We're an independent directory, not a sponsor. We list US giveaways and show the free way to enter each one, and we check mailing addresses word for word against the official rules. We never enter on anyone's behalf, and entering free doesn't mean you'll win. To see what's open, browse all giveaways.
Common questions
Is "no purchase necessary" always true?
On a legitimate sweepstakes, yes: there's a free way to enter. If you can't find one in the official rules, or there are no rules at all, the promotion may not be a sweepstakes, and that's a good reason to walk away.
What does AMOE stand for?
Alternate method of entry. It's the term used in official rules and by people who enter often, and it means any way to enter that doesn't require a purchase or a donation.
Does buying something improve my odds?
It depends on the promotion. On merch-backed giveaways, purchases earn more entries, so a buyer holds a larger share of the pool. On many brand sweepstakes entries aren't sold at all. The official rules will say which applies.
Can I enter from any state?
Not always. Sponsors can exclude states, and many do because of state registration or bonding requirements. Check the eligibility section of the rules before you enter.
