Fill Out Your Ballot

Voting by Mail

To make sure your vote is counted, there are a few rules to follow when filling out your ballot. 

  1. Sign the envelope between the two punch holes. Make sure your signature matches the signature of your voter registration record. If it doesn't match, your vote won't be counted. 
  2. Use a black or blue pen and completely fill in the circle (like you do for standardized testing).
  3. You don't have to mail in your ballot. Instead, you can drop it off at a designated County drop off box. 
  4. You can correct your ballot; you just need to make it clear.  Did you color in the wrong oval?  No worries, draw a large X through it and mark the oval that you want with arrows pointing towards it.  
  5. Your voter registration signature is your driver’s license signature or any other document that the County Elections Office has with your signature on it.
