Can I vote by mail in my state?

Eight states plus D.C. mail every registered voter a ballot automatically. Twenty-nine states let any voter request a mail ballot with no excuse. Thirteen states require a qualifying reason such as travel, illness, disability, or age. Enter your ZIP code at ballotbymail.org for your state's rule and deadlines.

When is the deadline to request a mail ballot for the November 3, 2026 election?

It varies by state, from three weeks before Election Day to the day before. Most fall between October 19 and October 30, 2026. Request deadlines are 'received by,' not postmarked.

Did the federal government ban mail-in voting?

No. Whether you can vote by mail is set by your state. A 2026 executive order changed how the Postal Service handles mail ballots and is being litigated. Request early and return by drop box or in person where available.

November 3, 2026 general election

Voting by mail in South Carolina

Only with a qualifying reason. You need an approved reason, such as travel, illness or disability, age, or work. Check your state's list. If you don't qualify, early in-person voting is usually an option. Ballots go out about 30 days before the election; the state says mail yours back at least a week early.

An immediate family member (spouse, parent, child, sibling, grandparent, grandchild, or in-law) or an Authorized Representative (a registered voter, for someone confined by illness or disability) may return it in person only, not by mail, to the county voter registration office or an early voting center, with the Authorized Returnee form and photo ID. Limit: five ballots besides their own; more is a felony. No drop boxes.

Steps

Check the excuse list on your state's site. Common ones: away on Election Day, illness or disability, 65 or older, work hours.
If you qualify, request now and include the reason exactly as the form asks.
If you don't qualify, look up early in-person voting. It's available in most excuse states.
When your ballot arrives, fill it out in blue or black ink and sign the envelope.
Return it the way your state requires and track it until it shows received.

Don't get rejected

Extra step in your state: any adult (18+) must witness your signature on the oath; no notary needed. This is the #1 reason ballots get tossed where it applies.
Sign the envelope. An unsigned envelope is the most common fixable mistake.
Use the secrecy sleeve if one is included, then the return envelope. Don't tape anything.
Keep the phone and email on your registration current. If there's a problem, that's how they reach you to fix it.
