You register by mail by filling out your state's registration form or the federal mail-in form, signing it, and mailing it to your election office before the deadline. Most states require the form postmarked or received a set number of days before Election Day. Include the ID or proof of address your state asks for, and confirm your registration afterward.
The process in five steps:
Your state's election website is the fastest source: every state publishes its own registration form as a printable PDF. There is also the federal mail-in voter registration form, created under the National Voter Registration Act, which is accepted in most states and comes with state-by-state instructions. If you don't have a printer, many public libraries, post offices, and county election offices keep paper forms on hand, and you can usually request one by phone.
Read the state-specific instructions on whichever form you use. A handful of states have quirks, and the instructions spell them out. North Dakota is the famous exception: it has no voter registration at all, so there is nothing to mail. Use the form that matches where you live and where you will vote, not where you used to live; registering in the wrong county is a common reason forms get rejected.
| What to include | Notes |
|---|---|
| Full legal name | Use the name on your ID, not a nickname |
| Residential address | Where you live, not a PO box, in most states |
| Date of birth | Required on every state's form |
| ID number | Usually your driver's license number or the last four digits of your Social Security number |
| Signature | Signed in ink; this is why the form usually must be mailed, not emailed |
| Party choice | Optional in most states; required if you want to vote in a closed primary |
First-time voters registering by mail for a federal election may need to include a copy of ID with the form under federal law, so check the instructions rather than assuming. Proof of address usually means something showing your name at your current address: a utility bill, bank statement, or lease. If you've moved recently, register at your new address; voting from an old address after you've moved can create problems, and most states let you update your registration by mail the same way.
Deadlines vary by state, which is the single most important thing to know. Most states set the cutoff several weeks before Election Day, and the rule differs: some require the form to be postmarked by the deadline, others require it to be received by the deadline. Received-by is stricter, so if your state uses it, mail the form with a comfortable cushion. Missing the cutoff usually means waiting for the next election, so don't guess at the date; look it up on your state election website.
A growing number of states offer Election Day registration, which removes the deadline pressure entirely, but most don't. With the US midterm elections on November 3, 2026, the registration deadlines land in October for most states, which is exactly when people start thinking about it. Register now rather than in the deadline week: election offices get swamped, processing slows, and a form with an error leaves you no time to fix it.
Don't assume the form arrived and was processed. Most states run an online voter registration lookup where you can check your status a week or two after mailing. If your name doesn't show up, call your county election office and ask; they can tell you whether the form arrived, whether anything was missing, and what to do next. Keep a copy or photo of the completed form before you mail it, so you can reference exactly what you sent.
In Canada, the process is simpler: Elections Canada lets you register online, by mail, or by phone, and you can also just register at the polls on election day with ID and proof of address. If you're registering by mail in Canada, the form goes to Elections Canada directly, and the voter information card they send back confirms you're on the list.
A practical note on signatures: most registration forms require your original ink signature, which is why people mail them rather than sending them electronically. LetterAgent can mail letters to election offices, but it can't sign a form for you, so the registration form itself is one you'll mail yourself. If you need to send a cover letter or a request for a form to an election office, that part a service like LetterAgent can handle.
