In most cases your ballot's return envelope arrives with postage prepaid, so you mail it back as-is with no stamp. If yours is not prepaid, attach the postage the instructions list. Adding an extra stamp never speeds delivery: election mail is already processed with all other first-class mail, and postal services deliver ballots even when postage comes up short.
One honest note up front: LetterAgent can't return your ballot for you. The ballot has to travel in its official return envelope with your vote inside, so there is nothing to print and no letter to send. This guide is about getting the postage right on the envelope you were given.
Look at the return envelope before you add anything. A prepaid envelope carries a printed postage indicia or a business-reply marking where a stamp would go, and the instruction sheet that came with your ballot will say postage is prepaid. Most states and counties now cover return postage, which is why this question comes up less than it used to. If the envelope has a blank corner and the instructions tell you to affix postage, it is not prepaid.
When it is not prepaid, follow the instructions exactly: they tell you how much postage to attach. Don't substitute your own envelope or repackage the ballot. The return envelope is part of the chain of custody, with barcodes and voter information tied to you. A ballot arriving in a plain envelope can be rejected, and no amount of correct postage fixes that.
It still gets delivered. USPS policy is to deliver election mail, including ballots, even when the postage is short; the shortfall is collected from the election office rather than from you. This is deliberate: nobody's vote should be lost over a few cents of postage. The same principle applies in Canada for Elections Canada mailings, which are designed to move without postage barriers for the voter.
That said, don't treat this as a plan. Put the right postage on if the envelope isn't prepaid, because short-paid mail can take a slower path through postage-due handling. And never assume a ballot with no postage at all in a non-prepaid envelope is fine; the policy covers shortfalls on election mail, not a blank corner on an envelope that was never set up for it. When the instructions say to add postage, add it.
No. This is the most persistent myth in ballot mailing. A first-class stamp is a first-class stamp; two of them don't buy priority handling, and ballots don't get a speed lane for extra postage. Election mail moves with all other first-class mail through the same processing and transportation. What actually determines whether your vote counts is timing: when you mail it relative to your state's deadline.
Know which deadline you are up against. Some states count ballots postmarked by Election Day; others require the ballot to be received by Election Day, which is stricter. With the US midterm elections on November 3, 2026, a ballot mailed the weekend before may be fine under a postmark rule and too late under a received-by rule. Check your state's rule on your election office's website, then mail early enough that the distinction doesn't matter. If you are cutting it close, skip the mail entirely and use an official drop box or vote in person.
| Step | What to do |
|---|---|
| Fill it out promptly | Don't let the ballot sit; decide and complete it as soon as it arrives |
| Sign where required | An unsigned return envelope is the most common reason ballots get rejected |
| Seal the official envelope | Use the return envelope provided, sealed as instructed |
| Check the postage | Prepaid means mail as-is; otherwise attach what the instructions say |
| Mail it early | Days before the deadline, not the day of; earlier is always safer |
The signature is worth a second look. Election offices verify the signature on the return envelope against the one on file, and a missing or mismatched signature is a far bigger threat to your ballot than postage ever is. Sign it the way you normally sign, seal the envelope, and get it in the mail with days to spare. Then track it: most states offer online ballot tracking so you can confirm it arrived and was accepted. If tracking shows a problem, you still have time to fix it, which is the real reason to mail early.
