Search NJDOC

The NJDOC Offender Search lists people in New Jersey state custody. You accept a disclaimer, then search. Write down the person’s SBI number: letters need it on the first line.

What the ADTC Is

NJDOC calls the ADTC a specialty mission facility for sexual offense treatment, and everyone held there is in treatment. Under New Jersey law, a judge can send a person there after an NJDOC psychological examination and a finding that they are open to treatment. The 2025 PREA audit counted about 420 men, ages 21 to 85.

The Special Treatment Unit

The Special Treatment Unit (STU) holds people civilly committed after their sentence ends. NJDOC handles custody, and treatment is run by a separate state health agency. The ADTC is the STU’s parent institution, and NJDOC gives the STU its own mail code, 1409.

Avenel or Woodbridge

NJDOC lists the address under both Woodbridge and Avenel, a community in Woodbridge Township. Same building.

When Records Come Down

People drop off the search one year after their custodial term ends, except people on community or parole supervision for life. Data is refreshed every two weeks.
