The simplest way to handle how to return to sender usps mail is to write “Refused” on the unopened piece and put it back in the mail. USPS returns it to the sender at no cost to you. It only works while the item is sealed.
The rule comes from the Domestic Mail Manual and covers letters, flats and packages. The details change if you open the item, sign for it, or hold a type of mail that cannot be refused for free.
How to return to sender USPS accepts without charge
An addressee may refuse a mailpiece when it is offered for delivery. After delivery, you may still refuse it if it is unopened and you send it back promptly. USPS explains this in its guidance on refusing unwanted mail.
- Leave the envelope or package sealed.
- Write “Refused” clearly on the front, near the address.
- Put it in your mailbox, hand it to your carrier, or drop it in a collection box.
- Do not add postage. USPS sends it back to the sender.
Do not cross out the address or tape over it. Just add the word and leave the rest as the sender printed it. That keeps the return path clear.
Can you write return to sender on mail?
You can write it, but “Refused” is the word USPS documents for mail you do not want. The Domestic Mail Manual list of nondelivery reasons (DMM 507, Exhibit 1.4.1) uses “Refused” alongside “Moved, Left No Address,” “Not Deliverable as Addressed,” “Attempted, Not Known” and “No Such Number.” Those are the markings USPS itself applies when it sends a piece back.
“Return to Sender” on its own is a plain language note, not one of those endorsements. Your carrier will usually understand it, but it gives USPS no reason code. Pair it with the reason that fits: “Refused” for mail you decline, or “Moved, Left No Address” for a former resident.
Use “Refused” and you remove any doubt. It also states the reason, which tells the sender the piece was not wanted. That is different from an address problem.
How to refuse a USPS package at the door
If a carrier offers you a package you do not want, say so before you accept it. Hand it back and tell the carrier you are refusing it. That is the cleanest route, because nothing has been signed or opened.
If you already took it but have not opened it, mark “Refused” on the label. Then return it the same way as a letter. A sealed package still counts as unopened.
Accountable mail works a little differently. For items that need a signature, check the “Refused” box on the delivery notice before you sign. Then put the notice or item back in your mailbox as directed.
What to write and what to do in each situation
| Situation | What to do | Cost to you |
|---|---|---|
| Unopened letter or package already delivered | Write “Refused” on it and return it to your carrier or mailbox | None |
| Offered by the carrier at the door | Decline it before accepting | None |
| Accountable mail with a delivery notice | Check the “Refused” box before signing | None if refused before signing |
| Opened mail, even if resealed | Cannot be marked “Refused”; use a new envelope or wrapper with the correct address | New postage |
| Registered, insured, Certified, COD or Adult Signature item already accepted | Cannot be refused postage free after delivery | You pay postage |
| Reply mail to your own promotion | Must have been refused when first offered | You pay postage if you missed that chance |
What if you already opened it?
Once you open a piece of mail, even if you reseal it, you cannot mark it “Refused.” Resealing does not restore the right. You need a different route.
Put the contents in a new envelope or wrapper. Add the correct address and new postage. To price that mailing, use the postage price calculator.
USPS also says a refused or undeliverable returned piece may not simply be remailed as it is. It needs the new wrapper, a correct address and new postage. If you are unsure which service fits, the mail class selector can help.
Which mail can you not return for free?
The free return has limits. After delivery, you cannot refuse these items without paying postage:
- Registered Mail
- Insured mail
- Certified Mail
- Collect on Delivery (COD) items
- Adult Signature pieces
- Reply mail sent in answer to your own promotions, unless you refused it when first offered
Class matters less than you might expect. Under DMM 507.1.8.3, Priority Mail Express, Priority Mail, First-Class Mail and USPS Ground Advantage pieces that cannot be delivered or forwarded go back to the sender at no additional charge, so a refused Priority Mail or Ground Advantage package costs you nothing to send back.
USPS Marketing Mail is the exception: you can refuse it without postage only if it is unopened and the sender printed “Address Service Requested,” “Forwarding Service Requested” or “Return Service Requested” on it (DMM 507.1.5.3). Marketing Mail with no endorsement is normally discarded rather than returned, so throwing it away is the practical outcome either way.
Is this how to return to sender USPS handles online orders?
No. Refusing is for mail you never wanted or never ordered.
If you bought something and want a refund, you are starting a return with the seller. That usually means a prepaid label or a paid return shipment. Read how to return a USPS package for that process.
If you refuse a paid order, the seller gets it back, but the refund still depends on the seller’s own policy. USPS does not set refund terms. Contact the seller first when the item is something you ordered.
Who can refuse mail with more than one name on it?
Each addressee controls delivery of their own mail. On jointly addressed mail, neither person can override the other’s objection to accepting it. If one person named on the envelope refuses it, the other cannot force acceptance.
What does return to sender mean on USPS?
It means the piece goes back to the sender instead of staying with the recipient. That can happen because the addressee refused it. It can also happen because the piece was undeliverable as addressed.
Senders can ask for return handling on their own mailings, which is a separate topic. See USPS Return Service Requested for how that endorsement works. For address correction notices, USPS lists $0.22 per electronic notice for First-Class Mail and Ground Advantage Retail, and $0.50 for other mail.
When to refuse and when to look closer
Refusing fits mail that is plainly not for you, such as junk, unwanted samples or pieces sent in error. It also fits an item you declined before signing. If you are unsure what a package is, check the sender and tracking first, because once you open it, you lose the free return.
Watch for a delivery notice on accountable mail. If the sender name is unfamiliar and a signature is requested, you can refuse before signing and avoid any postage cost. After you sign, you own the cost of sending it back.
Mail for someone who moved is a different problem
Refusing is not the only answer when mail is for a former resident. “Refused” tells the sender you declined it; “Moved, Left No Address” tells them the person is gone, which is the message that stops repeat mailings.
Write the second one when the addressee no longer lives there, and keep the piece sealed. For how to return to sender usps mail for a former resident, see what to do with mail from a previous tenant.
If your own mail is going to the wrong place, refusing will not fix it. You would need to change your address with USPS instead.
Stopping unwanted mail at the source
Refusing each piece will not stop repeat senders. For marketing mail, USPS points to DMAchoice, which charges a nominal fee to reduce prospect mail. It does not cover mail from businesses you already deal with, local retailers, restaurants or political groups.
For prescreened credit offers, call 1-888-5-OPT-OUT or visit optoutprescreen.com. Those two steps cut off most of the volume without touching each envelope.
Bottom line
To return to sender with USPS, mark unopened mail “Refused” and hand it back, and it goes free. Opened and accountable mail follow other rules, so expect to pay postage there. When in doubt, refuse before you open or sign.
