The Search Runs Citywide, the Answer Is One Building
The lookup takes either of two things.
A NYSID or a Book and Case number. The NYSID is a New York State identification number. The Book and Case number comes from the Department of Correction at admission. Both are exact.
A first name and a last name. This is where most families begin, since numbers arrive later than worry does. A common name returns a list and you choose from it.
The result gives the current location and basic case information, plus a Send Money button that routes to the transfer agents.
16-00 and 16-06 Are Not the Same Jail
This street runs on numbers that look almost alike, and two of them are close enough to cause real trouble.
Otis Bantum Correctional Center is 16-00 Hazen Street. It opened in June 1985, it has dormitory and cell housing, and it holds male adults.
West Facility is 16-06 Hazen Street. It opened in autumn 1991, it was built from sprungs, and the Department of Correction runs its Communicable Disease Unit there among other single-cell units.
Different jails, different populations, six numbers apart, with the street, the city, the state and the ZIP code identical. An envelope that gets everything right except those two digits still goes to the wrong place and still has to be forwarded.
Two Numbers, and Which One You Will Keep Using
The NYSID is a state number and you may never need it again. The Book and Case number is the one to write down the first time you see it.
It goes beside the person’s full name on every envelope. It is what a deposit through JPay or Western Union is keyed to. It is what the visit centre works from. Families who only ever hold a name end up doing all three of those the slow way.
The Gap Between an Arrest and a Record
The tool carries its own warning: not for persons in custody in police, state, or federal custody.
Someone arrested by the New York Police Department is in police custody through arrest, processing and arraignment, and does not appear in this system until the Department of Correction books them in. The department publishes no timing for that, so there is no number of hours to quote back at anyone.
What can be said is that the empty result in the first night is the expected result, not a sign that anything has gone wrong.
A Sentence Moves the Record, Not Only the Person
Somebody sentenced to state prison leaves city custody and enters the New York State system, which keeps its own separate lookup. Federal custody is a third system again.
So a record that stops appearing here has usually changed systems. Everything practical changes with it: the address, the visiting arrangements and the way money reaches them.
Run It Again Before You Post Anything
There is no family notification when a person is moved between jails on the island, and nothing the department publishes implies otherwise.
That leaves the search doing the work a phone call would do elsewhere. A minute before each letter, each deposit and each journey across the bridge is the whole cost of staying current.
