What the Lookup Gives You Back
Two ways in, and both reach the same record.
By NYSID or Book and Case number. The NYSID is a New York State identification number. The Book and Case number is assigned by the Department of Correction at admission. Either one is exact.
By first name and last name. Most families start here, because in the first days nobody has been given a number yet. A common name returns a list to choose from.
What comes back is the person’s current location and basic case information, along with a Send Money button that routes through to the transfer agents.
Two Commands at the Same Street Number
This is the thing worth understanding before you read a result.
19-19 Hazen Street houses two separate commands. One is the Rose M. Singer Center, the city’s jail for women. The other is RESH, the Rose M. Singer Center Enhanced Supervised Housing, which the Department of Correction’s facilities page describes as holding male detainees in restrictive housing.
Same address on the envelope, different command on the record. So a lookup result showing 19-19 Hazen Street tells you less than the command name does, and the command name is the part to write down.
The RESH Notice Is More Current Than the Facilities Page
The department’s two sources disagree, and the newer one is on the lookup itself.
The facilities page says RESH currently houses male detainees in restrictive housing, and adds that enhanced supervision units are reserved for people found guilty of disciplinary charges while in custody.
The lookup carries a notice saying RESH currently houses both people in restrictive housing and general population, and that people housed in RESH general population are not subject to restrictive status.
A family reading only the facilities page would take a RESH result as meaning restrictive housing. The notice on the lookup says that is not necessarily so. Where two official sources conflict, the one attached to the live tool is the more current, and it is also the kinder reading.
Searching Before the First Letter
The envelope needs three things: her full name, her Book and Case number, and the full name and address of the jail she is in. The lookup supplies two of the three.
Getting the jail name right is not a formality here. Six jails operate on Rikers Island, each with its own number on Hazen Street, and this is the only one the department names for women. If a search returns a different building, the address on your envelope changes with it.
Why a Search Right After an Arrest Finds Nothing
The tool states its own limit: it is not for persons in custody in police, state, or federal custody.
Somebody arrested by the New York Police Department stays in police custody through arrest, processing and arraignment. Until the Department of Correction books her in, she is not in this system and the search returns nothing. No timing is published for how long that takes, so there is no interval to wait out, only a process still running.
That first empty result is the one that frightens people most and means the least.
The Record Does Not Follow a Sentence
A state sentence moves a woman out of city custody and into the New York State system, where a different lookup applies. Federal custody is a third system again.
So a record that disappears from this tool has usually moved rather than vanished. What changes with it is the address, the visiting rules and the deposit route, none of which carry over from the city system.
Nobody Is Told About a Move
There is no notification to families when a person is moved between buildings on the island, and the department publishes nothing suggesting otherwise.
Running the search again before each letter, each deposit and each visit is the only way to catch a move, and it takes about a minute.
