Suffolk County publishes no roster and no lookup form, so the question of which of its two jails holds someone is answered by a phone call rather than a page. The search below is a quicker starting point.

This is a short page because the honest answer is short. Suffolk County does not publish an inmate search, and the page most search results point at is not real. What we can give you is the number that works, what to ask when you call, and why that call matters more here than at a county with one jail.
Several sites cite a Suffolk County inmate lookup page and describe what it returns, including current housing location. We checked, and it does not exist.
The county’s website is built so that any address under the Sheriff’s section returns the same Sheriff landing page. We confirmed that by requesting a deliberately nonsensical address, and the site returned identical output to the supposed lookup: same page, same title, no search form, no error.
There is also no roster anywhere in the Sheriff’s own site index, which runs to 80 pages. This is not a case of a tool being hard to find. There is no tool.
| What you need | Number |
|---|---|
| Custody status, records, bail information | 631-852-2241, staffed around the clock |
| Either jail, main line | 631-852-2200 |
| Visit reservations, once registered | 631-852-1893 |
Central Records is the one. It runs 24 hours, which matters when somebody has been arrested overnight and you are trying to find out anything at all before morning.
At a county with one jail you would ask one question. Suffolk has two, so make the call count.
One: which facility. Yaphank at 200 Glover Drive or Riverhead at 100 Center Drive South. Everything downstream depends on it, including which lobby kiosk to use and which building to drive to for a visit.
Two: the six digit identification number. The online Guest Registration form, which every visitor must complete before a reservation can be made, asks for it and will not proceed without it. The county publishes no roster to look it up in, so this call or your person are the only sources.
Three: whether they are likely to move. Yaphank holds a federal population that appeared from nothing in 2022 and has stayed, standing at 39 in August 2026 against 10 at Riverhead. Federal detainees move on a federal timetable.
New York’s county jails are covered by VINE, the statewide custody notification service run through the state’s sheriffs’ organisation, on 1-888-846-3469. It searches by name or identification number, refreshes roughly every 15 minutes for jails, and notifies on transfer as well as release. Records are purged about two weeks after somebody is released.
What we cannot confirm is whether Suffolk County feeds it. The county does not link VINE anywhere, and VINE publishes no directory of participating agencies. Suffolk is not on the list of New York agencies currently reporting themselves offline, which is mild evidence in favour and no more than that.
So it is worth trying, and it is not worth relying on. We are not going to tell you it works here when we could not verify that it does.
Booking has to finish before any record exists in any system, which takes hours rather than minutes.
The advantage at Suffolk is that Central Records is staffed through the night. At most county jails the records desk keeps office hours and an overnight arrest means waiting until morning to learn anything. Here you can ring at three in the morning and speak to someone.
Three different street numbers circulate for Suffolk, and all three are genuine.
And Yaphank has its own confusion: the county’s Civil Enforcement Bureau sits at 360 Yaphank Avenue, which handles evictions and property matters and has nothing to do with the jail at 200 Glover Drive.

No. The county publishes no roster, no lookup form and no booking feed. The Sheriff's own site index runs to 80 pages and contains none of those. Custody questions go to Central Records on 631-852-2241, which is staffed around the clock.
Inmate SearchBecause it does not exist. The county's site returns the same Sheriff landing page for any address under the Sheriff's section, so a link to a lookup page renders as an ordinary page with no search form and no error. We confirmed it by requesting a deliberately fake address and getting identical output.
Inmate SearchCall Central Records on 631-852-2241. Suffolk runs two jails under one set of published rules, and nothing online distinguishes which building holds a given person. Get that answer before you drive anywhere, because Yaphank is in Yaphank and Riverhead is about 20 miles east.
Inmate SearchPossibly. VINE is New York's statewide custody notification service, on 1-888-846-3469, and it covers county jails, searching by name or identification number and refreshing roughly every 15 minutes. What we could not confirm is whether Suffolk feeds it, because the county never links it and VINE publishes no list of participating agencies. Try it, but do not rely on it.
Inmate SearchAn identification number the Sheriff's Office issues to the person in custody. The online Guest Registration form requires it and will not proceed without it. With no public roster there is no way to look it up, so it comes from your person or from Central Records on 631-852-2241.
Inmate SearchYes, which is unusual. Central Records on 631-852-2241 is staffed 24 hours a day, so an overnight arrest does not mean waiting until offices open. Booking still has to complete before there is anything to tell you, and that takes hours rather than minutes.
Inmate SearchBecause all three are real and used for different things. 100 Center Drive South is the Riverhead facility and where bail is taken. 110 Center Drive South is the inmate mailing address covering both jails. The state oversight body lists 100 Center Drive without the word South. Check which one a page means before acting on it.
Inmate SearchAt Yaphank it is worth asking. Federal detainees appeared at this facility from nothing in 2022, reached 50 the following year, and stood at 39 in August 2026 against 10 at Riverhead. Federal transfers happen on a timetable Suffolk County does not set. Ask Central Records which custody applies when you call.
