How to Find Out a Jury Duty Number

Failure to register for duty, usually by filling out a questionnaire, or failing to report for duty can result in fines or even jail time. The jury duty number is a vital piece of information as it is used to identify and track a potential juror through the jury process – from registration to reporting to the courthouse. As juror numbers are handled by the county clerk, rather than individual courthouses, if you lose your number, you may be unable to complete phone-ins or complete check-in procedures on assigned dates.

Jury Summons

Open the jury duty summons and read it carefully. Identify the juror number or juror registration number, typically located near the top of the summons or on an attached juror registration card. Complete the registration process in order to obtain a juror group number. Check the local county clerk's website or call in during the specified period to determine when to go to the assigned courthouse.

Lost Jury Summons

Search for the county clerk's phone number or lost summons contact procedure on the clerk's website. Alternatively, find the phone number by using the yellow pages or visiting a local courthouse and asking for the information. Contact the clerk's office and inform them that the summons has been lost. Provide the requested identifying information and follow any other instructions. Wait to receive a new summons and store the information in a safe location.


  • Jury numbers and the registration process vary from state to state. Most county clerk's office websites will have an FAQ for new jurors unfamiliar with the selection and registration process.

    Jurors will typically be assigned two numbers: a longer personal identification number and a shorter group number. The group number is used to determine when to report to the assigned courthouse while the personal number is used to identify an individual juror.


  • The juror identification number is used in lieu of private identifying information such as social security numbers. You should not be asked to provide your social security number by representatives of the clerk's office.
