Can You Enter Sweepstakes With a PO Box?

Learn when a PO Box works for sweepstakes entry—and when winner verification or prize shipping requires a street address.
Yes, you can enter some sweepstakes with a PO Box. Whether a particular promotion accepts one depends on its official rules, including separate entry and prize-delivery requirements. A PO Box is a legitimate mailing address, but it is not proof of physical residence.
Before entering, check whether the sponsor asks for a mailing address, a residential address, or both.

Why the official rules control
Federal postal law defines a sweepstakes as a chance-based promotion that does not require a purchase. It requires mailed promotions to disclose entry procedures and rules, but it does not establish one address type for every entrant, according to U.S. Code §3001.
That leaves sponsors free to set address requirements within their official rules. Some accept PO Boxes, while others require a street address at entry, during winner verification, or before shipping a prize. Read the entire rule set rather than relying only on the entry form.
An online form may accept your PO Box even when another provision makes it unusable for prize fulfillment.
A valid mailing address can still be prohibited
USPS recognizes "PO BOX" followed by the box number as part of a complete delivery address in its Domestic Mail Manual. Therefore, a PO Box is not inherently an incomplete or invalid mailing address. However, postal validity does not override a sponsor's rules.
BenQ's published giveaway terms, for example, reject PO Boxes for both entries and mailed drawing prizes. Do not change your address format simply to bypass a restriction. If the rules prohibit PO Boxes, entering a street-formatted version of the same box may still fail the sponsor's requirement.
Entry eligibility and prize delivery are separate
A sponsor may use your physical residence to determine eligibility while requesting a different address for correspondence. This matters when entry is limited by location but prizes require delivery by a carrier or method that cannot serve a PO Box. ALDI's May 2026 Plane Packs rules illustrate the distinction.
Entrants had to physically reside in specified states, while potential winners had to supply a non-PO-Box U.S. mailing address; prizes could not be mailed to PO Boxes, and failure to meet winner requirements could lead to disqualification or forfeiture under the official giveaway rules. A sweepstakes might therefore allow you to enter with a PO Box but still require a street address if you win.
Check the "Eligibility," "Winner Verification," and "Prize" or "Shipping" sections before submitting your entry.
What to check before entering
Use this quick review: USPS Street Addressing, where available, lets eligible PO Box customers use the Post Office's street address and box number for qualifying packages from certain private carriers. That service expands delivery options, but it does not turn a PO Box into your residence or satisfy a rule demanding your actual physical address.
- Look for "PO Box," "P.O. Box," "physical address," "residential address," and "street address."
- Confirm whether the entry section permits your preferred address.
- Check whether winners must provide a different address for verification or delivery.
- Make sure your actual residence satisfies any geographic eligibility rule.
- Use a PO Box only when no applicable provision prohibits it.
