Voter Registration Information

In order to vote, you must be registered. Applications must be submitted at least 30 days before the election date.

In Texas, citizens do not register by political party, but simply register in their county of current residence. 

You are eligible to register to vote if:

  • You are a United States citizen;
  • You are a resident of the county where you submit the application;
  • You are at least 17 years and 10 months of age;
  • You are not a convicted felon (unless you have completed your sentence including any incarceration, probation, or parole); and
  • You have not been declared by a court exercising probate jurisdiction to be either totally mentally incapacitated or partially mentally incapacitated without the right to vote.

Voter Registration Certificate

Here is a diagram and some important information about your Voter Registration Certificate:


1.   VUID – This is your 10-digit statewide Voter Unique Identification Number issued by the Secretary of State’s office. This number remains the same as long as you are a registered voter in the State of Texas, regardless of the County in which you reside, or if you move from one County in Texas to another. 

2.   Precinct No. – Your voting precinct is based upon your residence address. Williamson County allows voters to vote at any open Election Day Vote Center. Voters are no longer required to vote in their specific precinct.

3.   Upon expiration, new certificates are automatically mailed to voters with active registrations.

4.   Residence Address – Your name and address of residence as provided when you registered to vote. Your voting precinct and districts are based upon this address.

5.   Please sign your certificate upon receipt.

6.   When voting in a primary election, you must state the party you would like to receive a ballot from. Your selection will then be indicated in this space. This also helps ensure you will receive a ballot from the same party should a runoff election be required. If you did not vote in the initial primary, but would like to vote in a subsequent runoff, you will be able to make your party selection at that time.  

7.   These are the districts in which you reside:

  • US Rep = United States Congress
  • State Senate and State Rep = Texas Legislature
  • Co. Comm = County Commissioner Precinct
  • J.P. =  Justice of the Peace District

8.   Mailing Address – Address provided by you to our office indicating where you wish to receive your mail. This address is not used in determining your precincts or in which races you will be eligible to vote.

BARCODE  #1 – This is an internal tracking number for mailing purposes.

BARCODE #2 – This is an internal tracking number which should be scanned by poll workers when presented at a polling location to check-in voters.

Did You Receive a Notice to Confirm Voter Registration Address?

These notices were mailed because we received information from the US Post Office that you may have moved from the address where you are registered, or your mailing address may have changed.

Please complete, sign, and mail back the yellow, postage paid Voter Registration Address Confirmation form.

If you have not moved, your returned form will be used to confirm your current address.

If you have moved within Williamson County, your returned form will be used to update your voter registration address.

If you have moved elsewhere in Texas, your returned form will be used to transfer your voter registration to your new county of residence.

If you have moved out of state, it is especially important to return the form so we may cancel your voter registration record.
