Visitation
Visiting at Union County DOC starts with approval—most New Jersey facilities require you to be pre-registered and on an approved visitor list before scheduling. Inmates typically add approved contacts during intake. Depending on the housing unit, visits may be in-person contact (where allowed), non-contact/screened sessions, or remote/video. Contact visits often come with extra rules: waiting periods, clean disciplinary records, or other eligibility requirements. If contact isn't allowed, non-contact options are usually available instead. Most visits are monitored or recorded (attorney visits are often the exception) and can be denied or ended for safety or rule violations. Bring a government-issued photo ID and complete any preregistration steps to avoid delays.

Union County's inmate look-up provides public access to selected offender information, in line with OPRA and the Sheriff's Division of Corrections' public safety mission. The roster lists inmates at Essex County Jail and Hudson County Jail rather than a Union County detention facility. Updates happen daily, but the site warns that information changes quickly and may not reflect someone's actual current location or status. Work release, furloughs, residential community program releases, and parole events may not appear in individual profiles. Some offenders can also be excluded from the public site at the Division of Corrections' discretion. One important warning: using this information to threaten, intimidate, or harass others may result in criminal prosecution or civil liability.
