An Alternative Method of Entry (AMOE) is the free entry path that keeps a purchase-linked sweepstakes legal. Without a compliant AMOE, any promotion that involves buying a product, entering a code, or uploading a receipt risks classification as an illegal lottery.

Despite being a foundational compliance requirement, AMOE design is where many brands make costly mistakes — from buried disclosures to unequal odds. This guide covers the requirements, the design options, and the pitfalls to avoid.

What Is an AMOE and Why Does It Matter?

AMOE stands for Alternative Method of Entry (sometimes called Alternate Means of Entry). It's the free entry path that satisfies the No Purchase Necessary requirement for sweepstakes that have any purchase-linked component.

The legal principle is straightforward: if you're running a promotion where participants can buy something to earn an entry, you must also offer a way to enter for free. The free method must provide the same chance of winning.

This requirement exists because U.S. law defines an illegal lottery as a promotion with three elements: prize, chance, and consideration (payment). A sweepstakes has prize and chance by definition. The AMOE eliminates consideration by ensuring no one must pay to participate.

The Four AMOE Requirements

A compliant AMOE must satisfy four criteria:

1. Equal Opportunity

The AMOE must provide the same chance of winning as the purchase method. This means:

Same number of entries per submission (if buying a product earns one entry, the AMOE earns one entry)
Same eligibility for all prize tiers (no "purchase-only" prizes)
Same weighting in the random drawing (an AMOE entry is not worth less than a purchase entry)
Same frequency limits (if customers can enter once per day via purchase, AMOE entrants can also enter once per day)

If your promotion offers bonus entries for purchases (e.g., "buy 3, get 5 entries"), the AMOE must also offer a path to equivalent bonus entries.

2. Reasonable Accessibility

The AMOE must be easy to find and easy to use. It should not require:

Extensive searching through fine print
Multiple clicks or page navigations from the main entry point
Special knowledge or insider information
Technology that creates a barrier (e.g., an app that only works on certain devices)

A reasonable consumer should be able to discover and use the AMOE without difficulty.

3. Not Materially More Burdensome

The AMOE can involve some effort — addressing an envelope, filling out a form — but it cannot be significantly more difficult than the purchase method.

Writing your information on a 3x5 card and mailing it is universally accepted — the cost of a stamp has never been ruled as consideration. Filling out a short online form (name, email, address) and calling a toll-free number during business hours are also fine.

On the other hand, requiring a notarized affidavit, demanding a multi-page essay, sending to a PO Box with a 4-6 week processing time when purchase entries are instant, or requiring travel to a specific physical location are all problematic. The test is simple: would a reasonable person look at your AMOE and feel it was designed to discourage use? If yes, it's too burdensome.

4. Available for the Entire Promotion Period

The AMOE must be open from the first day of the promotion to the last. You cannot:

Delay making the AMOE available after launch
Close the AMOE before the promotion ends
Limit the AMOE to certain days or hours (unless the purchase method has the same limits)

For mail-in AMOEs, entries postmarked by the end date should be accepted.

Types of AMOE

Mail-In AMOE

The most traditional and universally accepted AMOE. Participants hand-print their information on a 3x5 card or piece of paper and mail it to a designated address.

Standard mail-in language:

To enter without purchase, hand-print your full name, complete mailing address, email address, phone number, and date of birth on a 3" x 5" card and mail it in a #10 envelope to: [Promotion Name] AMOE, [Mailing Address]. Limit one (1) entry per stamped outer envelope per day. Entries must be postmarked by [End Date] and received by [End Date + 7-10 days].

Mail-in AMOEs are universally accepted by all jurisdictions, the cost of postage is not considered "consideration," the mechanic is simple to explain and implement, and it creates a physical paper trail. The downsides: processing mail takes time and staff resources, there is always a risk of lost or delayed mail, the gap between entry submission and processing creates timing challenges for instant win games, and some participants view it as outdated.

Best practices:

Use a dedicated PO Box or mailing address for the promotion
Process mail-in entries at least weekly (daily for short promotions)
Log each entry with the postmark date
Retain all physical entries for the duration of your record retention period
For instant win promotions, assign a game play to each mail-in entry using the same random algorithm

Online Free Entry Form

Increasingly common, especially for digital-first promotions. A standalone web form collects basic entry information without requiring any purchase, payment, or account creation.

Advantages:

Instant entry confirmation
Easy to track and process alongside purchase entries
Lower administrative cost than mail processing
Better participant experience

Disadvantages:

Must be truly free — no app download, account creation, or subscription required
Must be prominently linked from promotional materials (not hidden)
Some states may view mandatory data collection beyond basic entry info as a form of consideration

Best practices:

Host the form on a public URL that doesn't require login
Collect only the minimum information needed: name, email, mailing address
Do not require social media accounts, app downloads, or marketing opt-ins as a condition of form submission
Display the form link prominently on the main entry page and in official rules
Apply identical entry frequency limits (e.g., one entry per person per day)

Phone Entry (Toll-Free)

Some promotions offer a toll-free number where participants can call to enter.

Advantages:

Accessible to participants without internet access
No cost to the participant (toll-free)
Can serve as an accessibility accommodation

Disadvantages:

Requires staffing or an automated phone system
Business hours may limit availability
Higher cost per entry for the sponsor

Text Message (SMS) Entry

Participants text a keyword to a short code to enter. This method requires caution:

If participants incur standard messaging rates, some jurisdictions consider this a form of consideration
The safest approach is to pair SMS entry with a mail-in or online AMOE, rather than treating SMS as the AMOE itself
Disclose "Msg & data rates may apply" if using SMS entry

Hybrid AMOE

Many modern promotions offer multiple AMOE options — both a mail-in and an online form. This provides maximum accessibility and compliance coverage.

AMOE Design by Promotion Type

Receipt Upload Promotions

When the primary entry method requires uploading a purchase receipt:

Purchase path: Buy product, upload receipt photo, receive entry
AMOE: Submit online form (no receipt required) OR mail in a 3x5 card
Parity: One receipt = one entry, one AMOE submission = one entry
Frequency: If customers can upload one receipt per day, AMOE allows one free entry per day

Code-Under-Cap / On-Pack Promotions

When the primary entry requires a unique code found on product packaging:

Purchase path: Buy product, find code, enter online
AMOE option 1: Mail a self-addressed stamped envelope (SASE) to receive a free game code, then enter the code online
AMOE option 2: Submit a free online entry form (no code required)
Parity: Each free code or form submission equals one entry, same as a purchased code

The SASE method is traditional for code promotions but adds complexity. Many brands now prefer the simpler online form AMOE.

Instant Win Promotions

Instant win games add complexity to AMOE design because the game play itself — not just the entry — must be available to free entrants.

Purchase path: Buy product, enter code, play instant win game
AMOE: Submit free form or mail-in, then receive an instant win game play via email or the same game interface
Critical requirement: The instant win odds must be identical for purchase and AMOE game plays. The game's random number generator should not differentiate between entry methods.

Referral Promotions

When entries are earned through referrals:

Referral path: Refer friends, earn entries when they sign up or purchase
AMOE: Standalone free entry form (no referral required)
Parity: If each referral earns one entry, the AMOE earns one entry per submission, subject to the same daily or total limits

AMOE Processing and Record-Keeping

Processing Timeline

AMOE entries must be processed on a timeline comparable to purchase entries:

For sweepstakes drawings: All AMOE entries must be included in the drawing. Mail-in entries received by the receipt deadline should be entered before the drawing occurs.
For instant win games: AMOE entries should receive game plays within a reasonable timeframe. For online AMOE, this should be immediate. For mail-in AMOE, game plays should be assigned and results communicated within 7-10 business days.
For daily drawings: AMOE entries received that day should be included in that day's drawing.

Record Retention

Keep records of all AMOE entries for at least 3-4 years after the promotion ends (the statute of limitations for most sweepstakes-related claims). Records should include:

Entrant name and contact information
Date of entry (postmark date for mail-in)
Entry method (AMOE vs. purchase)
Game play results (for instant win)
Any correspondence with the entrant

Common AMOE Pitfalls

The "Technically Free" Trap

Some brands create AMOEs that are technically free but practically inaccessible:

A mail-in AMOE to a PO Box in a remote state with no indication of where to find the address
An online form buried three clicks deep behind a registration wall
An AMOE available "by request" with no clear instructions on how to request it

If a regulator or plaintiff argues the AMOE was designed to discourage use rather than provide genuine access, the brand's compliance defense weakens significantly.

Inconsistent Entry Limits

If purchase entries allow 5 entries per day and the AMOE allows only 1, the methods are not equal. Entry limits, bonus entry opportunities, and frequency caps must be consistent across all entry methods.

Ignoring AMOE Volume

Some brands are surprised when a significant percentage of entries come through the AMOE. This is normal and expected. If your AMOE receives a high volume of entries, that's actually a sign it's working as intended — it's accessible and participants are using it.

Never cap the total number of AMOE entries, slow down processing when volume is high, or remove or hide the AMOE mid-promotion because "too many" free entries are coming in. We've seen brands do all three. Every one of those decisions creates legal exposure.

Missing AMOE Disclosures

The AMOE must be disclosed in:

Official rules (complete instructions)
All advertising materials (abbreviated reference with "see official rules for details")
On or near the primary entry point
On product packaging (for on-pack promotions)

Missing any of these touchpoints creates a compliance gap.
