Will Your Mail Ballot Be Postmarked in Time?
- A machine postmark now shows the day a USPS plant first processes your mail, not the day you mailed it.
- In 15 states, D.C. and 3 territories, the postmark decides if a mailed ballot counts in the election of Tuesday, November 3, 2026.
- Check your ZIP code: your state's rule, your post office's truck schedule, and the safe way to mail.
Check Your ZIP Code
- Type the ZIP code where you will mail your ballot.
- You get your state's rule, whether your post office is on USPS's one-truck schedule, and what to do.
- Every rule comes with its source. More on the truck change: USPS RTO lookup and RTO map.
For the general election of Tuesday, November 3, 2026. State rules checked September 29, 2026: NCSL table of September 25, 2026 and each postmark state's election site. USPS post office data: report of August 3, 2026.
Last Day to Mail to Your Election Office
- Put the ZIP code of your election office in the To field: it is printed on your ballot's return envelope.
- The date is the day the ballot must arrive. Change it if your state gives more time.
- The result uses USPS's own First-Class Mail delivery standards for your exact route.
- A standard is USPS's target, not a promise: mail earlier than the last day shown.
The day it must be delivered.
The USPS Postmark Rule
A machine postmark carries the plant's date. A hand postmark at the counter carries that day's date, and it is free.
- USPS's Domestic Mail Manual: “If applied at a processing facility, the postmark displays the name or location of the processing facility and the date of the first automated-processing operation performed on that mailpiece.” Section 608.11
- USPS, January 2, 2026: “A postmark date does not necessarily indicate the first day that the Postal Service took possession of the mailpiece.” And: “This guidance is the same for all types of mailpieces, including mail-in ballots.” USPS statement
- Why: USPS says “we have made adjustments to our transportation operations that will result in some mailpieces not arriving at our originating processing facilities on the same day that they are mailed.”
- The fix, from the same manual: “Manual (local) postmarks are applied to mailpieces, upon a customer's request, free of charge at the retail counter of every Post Office, station, or branch.”
Why Rural Post Offices Matter
- Many post offices used to get two trucks a day: “a mail drop-off in the morning and an afternoon collection pickup trip” (Postal Regulatory Commission).
- USPS's Regional Transportation Optimization (RTO) cuts that to typically one truck for post offices more than 50 miles from their regional plant.
- Outgoing mail from those offices goes to the plant the next morning, not the same evening.
- USPS's report of August 3, 2026 lists 15,250 ZIP codes where the change has started. See them on our RTO map.
Every State's Rule for Mailed Ballots
- Postmark counts (19): Alaska, California, District of Columbia, Guam, Illinois, Kansas, Maryland, Massachusetts, Mississippi, Nevada, New Jersey, New York, Oregon, Puerto Rico, Texas, Virgin Islands, Virginia, Washington and West Virginia. The ballot must be postmarked by Election Day and arrive by a later deadline.
- Must arrive (37): everywhere else. The postmark date does not count. Louisiana's ballots must arrive the day before Election Day.
- On June 29, 2026, the Supreme Court ruled that federal law does not stop states from counting ballots postmarked by Election Day that arrive later (Watson v. RNC).
- Wording from the NCSL table (updated September 25, 2026). Postmark states also checked on their own election sites, September 29, 2026.
Kansas: a court case is still open
- “Beginning in 2026, all mail ballots must be received in the county election office, authorized drop box, or polling place by close of polls on Election day to be counted.”
- “A district court in Douglas County entered a statewide injunction requiring ballots postmarked by election day to be counted if a ballot arrives by the last postal delivery on Friday after the election.”
- “The Kansas Court of Appeals Court denied the Secretary of State's motion to stay the injunction for purposes of the Primary Election, but the Secretary of State filed a renewed motion with the Court of Appeals after the Primary asking it to stay the injunction for purposes of the General Election.”
- “Regardless of the decision, voters are urged to return their ballots by the close of polls on Election Day.”

- California: “If mailing on Election Day, get a hand-stamped postmark from a postal employee inside a United States Post Office.” Source
- New Jersey: “To make sure your ballot is postmarked on time, put your ballot in the mail at least a few days before election day, or go up to the counter at a U.S. Post Office and have a clerk manually stamp the postmark on your ballot envelope.” Source
- Texas: “Voters can ensure that a postmark is applied to their mail ballot envelope, and that the date on the postmark matches the date of mailing, by visiting a USPS retail location and requesting a manual (local) postmark at the retail counter when presenting their mail ballot envelope.” Source

Frequently Asked Questions
What date does a USPS postmark show now?
USPS's rule, in its Domestic Mail Manual (section 608.11): "If applied at a processing facility, the postmark displays the name or location of the processing facility and the date of the first automated-processing operation performed on that mailpiece."
So the date can be later than the day you mailed it. USPS, January 2, 2026: "A postmark date does not necessarily indicate the first day that the Postal Service took possession of the mailpiece."
Is a hand postmark at the post office free?
Yes. USPS: "Manual (local) postmarks are applied to mailpieces, upon a customer's request, free of charge at the retail counter of every Post Office, station, or branch."
A hand (manual) postmark shows the day the counter accepted your mail.
Which states count a mailed ballot by its postmark?
15 states: Alaska, California, Illinois, Kansas, Maryland, Massachusetts, Mississippi, Nevada, New Jersey, New York, Oregon, Texas, Virginia, Washington and West Virginia, plus Washington, D.C., Guam, Puerto Rico and the U.S. Virgin Islands (NCSL, updated September 25, 2026).
Your ballot counts there if it is postmarked by Election Day and arrives by your state's later deadline. Kansas is unsettled: a court case is still open.
Did the Supreme Court change this for 2026?
No change to the state rules.
On June 29, 2026, in Watson v. Republican National Committee (5-4), the Supreme Court ruled that federal law does not stop states from counting ballots postmarked by Election Day that arrive later.
NCSL: "all existing state laws on the timeline of absentee/mail ballot receipt remain in place."
How early should I mail my ballot?
USPS advises mailing "before Election Day, and at least one week prior to the deadline" by which your election office must receive the ballot.
Where the ballot must arrive by Election Day, that means by Tuesday, October 27, 2026 (Louisiana, where ballots must arrive the day before: Monday, October 26, 2026).
Where the postmark counts and you mail close to the deadline, hand it in at a post office counter and ask for a hand postmark.
Why can a ballot mailed on time get a late postmark?
A machine postmark is applied at the processing plant, with the day the plant first processes the mail.
USPS used to send many post offices two trucks a day, "a mail drop-off in the morning and an afternoon collection pickup trip" (Postal Regulatory Commission).
Under RTO, post offices more than 50 miles from their plant typically get one: outgoing mail goes to the plant the next morning, so it can get the next day's date.
Does the postmark matter where the ballot must arrive by Election Day?
Not for counting it: in 35 states (and American Samoa and the Northern Mariana Islands) the ballot must arrive in time, whatever its postmark.
There the delivery time is what matters: our calculator shows the last day to mail to your election office.
