Suffolk County Inmate Population
The Suffolk County inmate population is held in two county correctional facilities operated by the Suffolk County Sheriff's Office under Sheriff Dr. Errol D. Toulon, Jr. Riverhead is the primary county jail, and Yaphank is the second local correctional facility. Both hold male and female incarcerated people at minimum, medium, and maximum security levels. The county count includes people waiting for court, people serving local sentences, state-ready people waiting for transfer, and smaller groups held for other legal reasons.
Official population numbers come from several sources. The sheriff publishes facility capacity and program information. The State Commission of Correction reviews maximum facility capacity and jail oversight matters. New York DCJS publishes annual and monthly jail population trend reports. Those sources show a Suffolk County inmate population that fell sharply in 2020 and then rose back near its pre-2020 level by 2025, with Yaphank holding the larger share in recent reports.
Suffolk County Inmate Population Statistics
The main Suffolk County jail population figures are capacity, average census, and the split between Riverhead and Yaphank. The sheriff's Corrections Division page lists Riverhead at 840 maximum capacity and Yaphank at 976 maximum capacity. The DCJS Annual Jail Population Trends report prepared February 2, 2026 lists 2025 average census as 500 at Riverhead and 589 at Yaphank.
| Measure | Figure | Source / Date |
|---|---|---|
| Riverhead maximum capacity | 840 | Suffolk Sheriff Corrections Division; SCOC May 22, 2024 packet |
| Yaphank maximum capacity | 976 | Suffolk Sheriff Corrections Division |
| Combined 2025 average census | 1,089 | DCJS Annual Jail Population Trends, prepared February 2, 2026 |
| Latest combined monthly census listed | 1,043 | DCJS Monthly Jail Population Trends, prepared June 1, 2026 |
The official corrections page identifies the two facilities and their capacities.
That capacity source matters because it separates Riverhead from Yaphank instead of treating Suffolk jail custody as one building.
Suffolk County Inmate Population Trends
DCJS annual data shows the Suffolk County inmate population moved through three clear phases. The combined average census was 1,238 in 2016 and 1,296 in 2017. It then declined before the 2020 drop, reaching 1,084 in 2019. The 2020 combined average was 569, followed by steady growth through 2025.
By 2025, the combined Riverhead and Yaphank average census was 1,089. That is close to the 2019 level, but the mix changed. Yaphank reported a higher 2025 average census than Riverhead, and Yaphank also had more state-ready and federal-counted people in the DCJS category table. The monthly report prepared June 1, 2026 then showed the final listed month at 505 for Riverhead and 538 for Yaphank.
| Year | Riverhead | Yaphank | Combined |
|---|---|---|---|
| 2016 | 589 | 649 | 1,238 |
| 2019 | 498 | 586 | 1,084 |
| 2020 | 309 | 260 | 569 |
| 2023 | 416 | 476 | 892 |
| 2024 | 417 | 550 | 967 |
| 2025 | 500 | 589 | 1,089 |
Suffolk County Jail Population Makeup
Public Suffolk jail data gives strong custody categories, but it does not publish a full public race, age, or gender count table in the research source set. The official pages do state that both county facilities hold male and female incarcerated people across minimum, medium, and maximum security classifications. DCJS 2025 categories show a large unsentenced population, plus sentenced, civil, federal, technical parole violator, and state-ready categories.
- Other unsentenced: DCJS lists 380 at Riverhead and 408 at Yaphank in the 2025 annual row.
- Sentenced: The same DCJS row lists 63 sentenced people at Riverhead and 98 at Yaphank.
- State-ready: Riverhead listed 8 and Yaphank listed 32 people waiting for state transfer in the 2025 row.
- Program populations: Riverhead houses Choose Your Path, while Yaphank houses SATP, Veterans Pod, 55+ Pod, Choose to Thrive, and START-related services.
Suffolk County Jail Capacity
The combined stated maximum capacity of the two Suffolk County correctional facilities is 1,816. That does not mean every bed is usable for every person. Classification, gender separation, medical needs, protective custody, program housing, and court movement can limit where someone may be housed. The 2025 combined average census of 1,089 sits below stated capacity, but operational crowding can still occur inside a housing category or medical unit.
The Riverhead capacity source is especially detailed. The State Commission of Correction May 22, 2024 packet says Riverhead was built in 1969, expanded by 300 beds in 1980, and had a current maximum facility capacity of 840 beds at standard. It also describes 38 individual occupancy housing units and 3 multiple occupancy housing units. Yaphank's published profile is different: it has dormitory and podular housing, a medical pod, and several specialized program units.
Laws for Suffolk County Jail Data
New York law affects both access to Suffolk County inmate population data and the limits on release of some jail records. FOIL creates the request path for agency records, while Correction Law sections give the state oversight commission access to jail records and facilities. Booking photographs receive more privacy protection than many readers expect.
Key statutes:
Public Officers Law Article 6 is New York's Freedom of Information Law for agency records.
Public Officers Law section 89 covers FOIL procedure and includes the booking-photo privacy limit.
Correction Law section 45 gives the State Commission of Correction inspection and oversight powers.
Correction Law section 500-c places county jail custody with the sheriff where that structure applies.
Note: The sheriff's FOIL page says the office generally provides incarceration records only for people held at Suffolk County correctional facilities.
Search Suffolk County Inmate Population
Suffolk County does not appear to publish a traditional sheriff-hosted public jail roster with current inmate profiles and mugshots. The practical search chain starts with VINELink New York for custody and notification, then Central Records if the online result is unclear. For bail and real-time custody questions, the sheriff's bail page identifies Central Records as the key contact.
Use the Suffolk Sheriff FOIL process for historical incarceration records, older booking information, or records that are not available through phone or VINE. Use DOCCS incarcerated lookup only after a person is sentenced to New York state prison. Use BOP inmate locator for federal custody and ICE ODLS for immigration custody.
- Start with VINELink New York when the goal is current custody status or release notification.
- Call Central Records with the person's full legal name, date of birth, and approximate arrest date if VINE is unclear.
- Ask whether the person is at Riverhead or Yaphank, whether bail is set, and whether another hold blocks release.
- Search WebCriminal for court charges after arraignment or filing.
- Switch to DOCCS, BOP, or ICE when the custody type is state, federal, or immigration custody.
Suffolk County Custody Search Fields
Because the official source sweep did not locate a Suffolk sheriff roster form, the most accurate field table is the public VINE and locator field inventory from the research. VINE is a custody and notification system, not a complete booking database. It should not be described as a guaranteed roster or mugshot source.
| Channel | Search Fields | Use It For |
|---|---|---|
| VINELink New York | Name or ID-style app workflow where available | Current custody and notifications |
| Central Records | Full name, date of birth, approximate arrest date, Sheriff's PIN if known | Real-time custody, bail, holds, transfer questions |
| DOCCS lookup | DIN, NYSID, or last name with optional birth year | Sentenced New York state prison custody |
| BOP locator | Name fields or Register, DCDC, FBI, or INS number | Federal custody from 1982 to present |
| ICE ODLS | A-number or name with country of birth and birth date | Adults in ICE custody or CBP custody for more than 48 hours |
The New York VINELink portal is the statewide custody and notification starting point for many local custody checks.
When a VINE search does not answer the question, the next step is direct confirmation through Suffolk Central Records or a FOIL request.
Suffolk County Inmate Record Details
A Suffolk County jail record may require more than one source. VINE can help with custody and notification. Central Records can answer practical questions about current location, bail, holds, and release processing. A FOIL request can be used for incarceration records held by the sheriff. Court charges, court dates, and dispositions are separate court records.
| Data Point | Where It Is Most Likely Confirmed |
|---|---|
| Current jail custody | VINELink or Central Records |
| Facility location | Central Records, VINE result, or jail staff |
| Six-digit Sheriff's PIN | Visitor registration or family coordination with the jail |
| Formal charges | New York WebCriminal or court clerk |
| Historical incarceration dates | Sheriff FOIL request |
| State prison location | DOCCS incarcerated lookup |
Suffolk County Jail vs State Prison
A county jail search and a state prison search answer different questions. Suffolk County jail custody is local and usually tied to arraignment, bail, short sentences, court production, and transfer movement. State prison custody begins after a state sentence and transfer into the DOCCS system. Federal and immigration custody are separate again.
| County Jail | State Prison | |
|---|---|---|
| Run By | Suffolk County Sheriff's Office | New York State DOCCS |
| Who It Covers | Pretrial, short-sentence, local holds, court movement | People sentenced to state prison |
| Lookup Route | VINE, Central Records, FOIL | DOCCS incarcerated lookup |
| Common Confusion | May not show a public roster profile | Does not show county jail detainees |
Suffolk County Detention Facilities
The Suffolk County inmate population is local to two county correctional facilities. No active DOCCS prison, BOP prison, or ICE detention facility was found in Suffolk County official sources. Federal defendants from Suffolk County may be held elsewhere in the Eastern District of New York, and sentenced state prisoners move into the statewide DOCCS system after transfer.
- Suffolk County Correctional Facility - Riverhead holds male and female county incarcerated individuals and includes linear and podular housing, medical care, visiting, and the Choose Your Path program.
- Suffolk County Correctional Facility - Yaphank holds male and female county incarcerated individuals and includes dormitory and podular housing, SATP, Veterans Pod, 55+ Pod, Choose to Thrive, and START-related services.
Suffolk County Jail Access Basics
Bail, visiting, mail, phone, and deposits depend on the person's location and custody status. The sheriff's bail page says Central Records is available at (631) 852-2241. Riverhead accepts bail at all hours, while Yaphank accepts bail during the published daytime and evening window. All bonds are accepted only at Riverhead.
Family visiting is appointment only through the published visiting reservation number. The visitor form asks for the incarcerated person's first name, last name, date of birth, and six-digit Sheriff's Office PIN. Mail goes to the Suffolk County Correctional Facility mailing address at Center Drive South in Riverhead, and the sheriff lists white-envelope and photo-size rules that should be checked before anything is sent.
Suffolk County Court Records After Arrest
Custody status and court records should be checked separately. A jail entry may show that a person is held, but the court record shows filed charges, future dates, and disposition. The official New York WebCriminal portal supports case identifier, defendant, and court calendar search paths. The Suffolk 10th Judicial District page helps identify the correct court for Suffolk criminal matters.
For court-record details after release from jail, use the court system rather than the jail. The jail can process custody and bail paperwork, but prosecutors may amend, reduce, add, or dismiss charges after review. Booking does not equal conviction.
Suffolk County Jail Mugshots
No official Suffolk sheriff-hosted public mugshot gallery, recent-bookings page, or roster profile with booking photos was located in the research sweep. New York also treats law-enforcement arrest or booking photographs differently from basic custody data. Public Officers Law section 89 allows agencies to treat disclosure as an unwarranted invasion of personal privacy unless a specific law-enforcement purpose supports release and no other law blocks it.
That means Suffolk County jail mugshots should not be promised as an online roster feature. A person seeking a booking photo tied to Suffolk jail custody should use the sheriff FOIL route and expect that the photo may be denied, limited, or redacted. Commercial mugshot sites are not official custody sources.
