Registering and requesting your ballot

Request your Missouri ballot

One federal form registers you and requests your absentee ballot. Overseas voters file it again every election year, even if you voted last time.

Missouri asks new registrants for the last four digits of your Social Security number or a state-issued ID or driver's license number.

Receiving your blank ballot

Once Missouri accepts your form, it sends you a blank ballot — federal law requires states to transmit them to overseas voters at least 45 days before Election Day, so yours should be sent by September 19, 2026.

Ballot not arrived by September 19, 2026?

If it has not reached you, tell us — we track delivery issues and raise them with election officials.

Returning your Missouri ballot

Missouri lists an electronic way to return a voted ballot as well as post, but it limits who may use it. Missouri accepts an emailed or faxed ballot only from voters in a hostile fire area. For everyone else it is post only. Post is open to every overseas voter; check the electronic option with your local election official before you rely on it.

Return your ballot according to the instructions that came with it — the envelopes, the signature and any witness or ID requirement are set by your state. If anything is missing or you are not sure what they want, your local election official is the person to ask.

4 ways to return it — choose one

Post

Post your voted ballot in the return envelope from your packet. International postage from your country applies, and delivery takes two to three weeks from most places.

Received by Nov 3, 2026 at 7 PM local time

Postmarked by Nov 3, 2026

It must still arrive within 3 days of Election Day.

International post is slow — allow about three weeks from most countries, and longer from some. Count back from the deadline above rather than from today: post costs nothing and needs the most time, a courier reaches Missouri in a few days for a fee.

Fax

Limited — check first

Fax your voted ballot and any forms in your packet to your election office. The number comes with your ballot; online fax services work from anywhere.

Received by Nov 3, 2026 at 7 PM local time

Not every overseas voter may use this. Check with your Missouri election official before you rely on it.

Email

Limited — check first

Scan or photograph your voted ballot and any forms in your packet, and email them to your election office. The address and any cover sheet come with your ballot.

Received by Nov 3, 2026 at 7 PM local time

Not every overseas voter may use this. Check with your Missouri election official before you rely on it.

By courier — DHL, FedEx or UPS

Faster, costs more

A courier takes a few days instead of a few weeks and gives you tracking. It costs more than ordinary post, and how much depends on the country you are sending from.

Same deadlines as returning by post:

Received by Nov 3, 2026 at 7 PM local time

Postmarked by Nov 3, 2026

It must still arrive within 3 days of Election Day.

Many election offices publish a PO box, and couriers cannot deliver to one. Look up your election office and ask for a street address that accepts courier deliveries — before the day you plan to send.

Missouri accepts an emailed or faxed ballot only from voters in a hostile fire area. For everyone else it is post only.

Missouri overseas voting questions

What is the Missouri ballot deadline for overseas voters?

As early as November 3, 2026 at 7 PM. Varies by how you send it.

What if my Missouri ballot has not arrived?

If your ballot has not arrived and your deadline is close, the Federal Write-In Absentee Ballot is the federal backup ballot. You can fill it in for federal offices and send it now; if your real ballot turns up later, complete and return that too — only one of them is counted. In Missouri, the backup ballot can also register you to vote, though registration deadlines may fall earlier than ballot deadlines.

Can I email or fax my ballot back in Missouri?

Not everyone can. Missouri accepts a voted ballot by email, fax or post, but it limits who may use the electronic options.
