Mail or hand-deliver your ballot to your Local Election Office. You can also hand-deliver your ballot to a state-provided dropbox.
Your ballot must be received by the deadline or it will not be counted.
Two important things to note:
The Local Election Office will compare your signature on your voted ballot to the one on your driver’s license and on your voter registration form to make sure they match. So please sign carefully.
The post office will deliver your ballot even if you don’t have a stamp as long as you use the return envelope provided by your state. This envelope will say “official election mail.” The USPS will always deliver official election mail -- no stamp needed.
