Being on call for jury duty means you have been summoned to a juror pool but are not required to sit at the courthouse waiting for a case. Instead, you check in each day during your service window to find out whether your number is being called to report. Most on-call periods run one to two weeks in state courts and up to one month in federal courts, and plenty of people finish the obligation without ever setting foot in a courtroom.
How On-Call Status Works
Your summons assigns you a participant number or juror ID that ties you to a specific pool. During your service window, the court does not want everyone showing up at once. It calls jurors in batches as trials actually need them, and the rest of the pool stays home and waits for instructions.
The length of the window matters because it defines how long you need to stay available. A state court might only hold you for a week or two. A federal court can keep you on call for roughly a month. Within that window, you might be told to report once, several times, or not at all.
How You Find Out Whether to Report
You check your reporting status each day using one of two methods: an automated phone line or a juror web portal. Your summons tells you which one to use and when to check, usually the evening before a potential service day.
When you call or log in, you enter your participant number. The system tells you whether your number falls within the range being called to report the next day. If it does, you show up at the time and location given. If it doesn’t, you go about your day and check again at the next scheduled time. This repeats until the window closes or you’re asked to report.
What You Can and Can’t Do While On Call
On-call status is not house arrest. You can work, run errands, and live normally. The real obligation is availability. You need to be reachable and able to get to the courthouse with roughly one evening’s notice. Keep your phone charged, check the reporting system on time, and don’t book a flight out of state during your window. Some summonses spell out specific travel restrictions, so read yours.
Tell your employer as soon as the summons arrives. Most people need at least a day to shift meetings, move deadlines, or hand off work. The earlier your manager knows, the easier the adjustment if your number does come up.
What Happens on a Day You’re Told to Report
When the system tells you to report, it gives you a date, time, and location, usually a jury assembly room. Bring your summons paperwork and a valid photo ID. You’ll clear a security checkpoint, check in with court staff, and wait with other potential jurors.
Dress business-casual. Shorts, tank tops, flip-flops, and hats (other than those worn for religious reasons) are typically not allowed in courtrooms, and jurors who show up dressed inappropriately risk being sent home and rescheduled. Courtrooms also run cold, so bring a sweater.
You can generally bring a phone, laptop, or tablet to pass the time in the assembly area. Most courts let you read, listen to music with headphones, or get work done while you wait. The hard rule is that you cannot use any device to research, discuss, or post about a case you might be assigned to. No Googling the parties, no texting friends about what you overheard, no social media posts about the trial.
From the assembly room, groups of jurors are sent to individual courtrooms for jury selection, formally called voir dire. The judge and attorneys ask questions to determine whether you can be fair and impartial on that particular case. You might be selected for a trial, excused from that panel and sent back to the assembly room, or released for the day. Being called to report does not guarantee you’ll sit on a jury. Many people report once or twice during their on-call period and never serve on an actual trial.
If the Timing Doesn’t Work
If your service window is genuinely bad, you can usually postpone rather than ignore the summons. In federal courts, you can typically postpone up to two times within one year of your original report date, and the process is often handled through the court’s online juror portal. State courts set their own rules, but most allow at least one deferral if you ask promptly.
Getting excused entirely is harder. Courts grant excuses for undue hardship or extreme inconvenience, and you’ll need documentation. Medical conditions require a signed physician’s statement. Financial hardship requires tax forms or pay records showing that service would genuinely prevent you from supporting yourself or your family, not just that you’d lose some income. Full-time students and sole caregivers for young children or disabled family members may also qualify with proof.
In most federal districts, people over 70 can request a permanent excuse from jury service. The same applies to anyone who has served on a federal jury within the past two years and, in some districts, active volunteer firefighters or rescue squad members.1United States Courts.

What Happens if You Ignore the Summons
Courts track who checks in and who doesn’t. Ignoring your summons can trigger a contempt finding. In federal court, a person who fails to appear and can’t show a good reason may be fined up to $1,000, jailed for up to three days, ordered to perform community service, or hit with some combination of all three.2Office of the Law Revision Counsel. 28 USC 1866 – Selection and Summoning of Jury Panels
State courts impose their own penalties, often with escalating fines for repeat violations. A judge can also issue a bench warrant compelling you to appear and explain yourself. The simplest path is to check the reporting system on schedule and show up when your number is called. If you truly cannot serve, requesting a postponement or excuse is always better than going silent.
