Label basics

Can you ship without a return address?

For a parcel label, realistically no. USPS rules require a legible return address on Priority Mail and a long list of other mail types, per pe.usps.com DMM 602.1.5.3, and every label sold through our checkout prints the sender address you enter. The good news for privacy-minded shippers: that address has to be real and reachable, not personal.

Sender and recipient are both part of the label data the carrier prices. The flat-mailer rates below are from 2026-07-27.

Flat mailer rates, quoted 2026-07-27

Since this question usually comes from people sending documents or small flats, our reference quote is a 13 × 9 in flat mailer under half a pound, Newark, NJ (07102) to Atlanta, GA (30303). Every row shows the complete amount charged at checkout.

UPS Ground stood out on quote day: a 2-3 day window for three dollars over the slowest row. Whatever you pick, the label will name a sender, and that's a feature; it's the mechanism that brings a missed delivery back to you instead of into a dead-letter pile.

What the DMM actually requires

Per pe.usps.com DMM 602.1.5.3, checked 2026-07-27, the sender's domestic return address must appear legibly on a defined list of mail types, including Priority Mail, Priority Mail Express, Registered Mail, Certified Mail and insured mail, among others. Modern parcel services live on that list, so a labeled package without a sender line isn't a loophole; it's a nonconforming piece.

Privacy without anonymity

The sender field needs an address that can accept a returned box. It doesn't need to be your house. Sellers who prefer distance from buyers routinely use a rented mailbox, a business suite or a shop address. Pick the spot a bounced package should land, enter it as the from address, and the label does the rest.

Why our labels always name a sender

The from address feeds the rate itself; origin ZIP is half of the zone math that prices every quote on this site. It also feeds pickup, returns and claims. Stripping it would break the product long before it broke any rule, which is why no toggle for it exists in our checkout and we would not add one.

Return address questions

Does USPS require a return address?

On many kinds of mail, yes. Per pe.usps.com DMM 602.1.5.3, checked 2026-07-27, a sender's domestic return address must appear legibly on Priority Mail, Priority Mail Express, Registered Mail, insured mail and more than a dozen other categories. Parcel labels bought online fall squarely in that world.

Can the from address be a PO Box instead of my home?

Enter whichever real address should receive the package if delivery fails; for many shippers that is a box or a business location rather than a residence. The requirement is that the address works, not that it reveals where you sleep.

What happens to a package that cannot be delivered?

The carrier tries to send it back to the sender address on the label. A parcel with no usable sender line has nowhere to bounce, which is a big part of why the rules and the label formats insist on one.

What does a flat mailer cost to send?

Our 2026-07-27 quote for a roughly 13 x 9 in flat under half a pound, Newark to Atlanta, started at $8.38 with USPS Ground Advantage, with faster tiers topping out at $15.38 for UPS 2nd Day Air.
