Change or confirm your registered signature

Trained employees at King County Elections compare the signature on every mailed ballot envelope with the signature on the voter's registration. Ensure your ballot encounters no problems with processing; there are three ways to update your voter registration signature.

1. Update online. Make your signature change online by linking your driver’s license or identification number with your voter registration record. Go to MyVoteexternal link and follow the prompts.

2. Prefer paper? You can  download, print, complete and sign this form (pdf)external link from the Washington Secretary of State. Then mail it or deliver it to our office in person.

3. In person. Update your signature in person at the King County Elections Office or the King County Voter Registration Annex

Be aware of deadlines

Make your updates 29 days before the next election.

If there is a problem

King County Elections will mail a letter to your address (and call and/or email if we have that contact information on file):

  •  If you have forgotten to sign the oath on the back of the return envelope or
  • If the signature on the return envelope does not match the signature we have on file.

Please respond promptly in order to make sure your ballot can be counted, even if Election Day has passed.

Voters must resolve issues with their signatures prior to certification.

For the November 3, 2015 special election,
the deadline is November 23. 

The mailing from King County includes instructions and deadlines for returning documents. Voters with questions can call 206-205-5686 for assistance.

Your signature is important

If a voter’s signature on the ballot return envelope does not match the signature on the voter registration record, we cannot process that ballot until the voter remedies the problem. Voters should periodically update their signature with Elections to avoid a signature challenge.

In addition, if you forget to sign the envelope or the signatures don’t match, Election officials will attempt contact by both phone and mail so that your ballot can be counted.

Why should I update my signature?

Your signature may change for many reasons: name change, the passage of time, physical changes or simply changing the way you sign your name.

If the signature on your ballot return envelope does not  match the signature on your voter registration record, we cannot process your ballot until the you remedy the problem. 

For these reasons, you should periodically update your signature with Elections to avoid a signature challenge.
