View ArticleWestchester runs a genuine name search with first name, last name, partial matching, alias inclusion and date of birth filtering, which is better than most county tools. The catch is published by the county itself: not everyone in custody appears, and people can be withheld for security reasons or by the type of person held. That makes the phone line the more reliable answer when a search comes back empty.
See the full breakdownVisits run seven days a week in six fixed one hour slots, all booked in advance by telephone on a line that only answers weekday mornings. Two one hour visits a week, of which at most one can fall at a weekend. Weekend and Monday visits all close at 1 PM on the preceding Friday, and processing shuts 30 minutes after a slot begins whatever time the visit itself ends. Attorneys and other professionals work to a separate walk-up schedule.
See the full breakdownEverything goes to one post office box in Valhalla, and the county publishes a long list of what stops a letter reaching the person it is addressed to. White paper only, blue or black ink only, no crayon, markers, gel pen, lipstick, glitter, laminate or musical cards. Photos are capped at twelve, and instant prints are refused outright.
See the full breakdownMoney runs through TouchPay, at kiosks in the jail lobby on weekday hours or through the website at any hour, and commissary gifts run separately through iCare. Packages have their own window, split around a closure in the middle of the day. Bail is a third system again, taken in cash or on a card around the clock.
See the full breakdownCalls come out of the jail collect, so an AdvancePay account on the family's side is what makes them possible. Nobody can call in, and the county states that residents cannot receive calls or messages at all. There is also a published form for households that want the calls to stop, which is rarer to see written down than it should be.

Visits run Monday through Sunday in six one hour slots, starting at 9:10, 10:20, 11:30, 1:15, 2:30 and 3:45. Every one is booked in advance on 914-231-4116, and that line only answers weekdays between 9 AM and 1 PM. You get two one hour visits a week with at most one at a weekend.
VisitationSaturday, Sunday and Monday, all three. They must be scheduled no later than 1 PM on the preceding Friday. Monday being in that group is the part families miss, and it means somebody taken into custody on a Friday afternoon cannot be visited until Tuesday.
VisitationOne campus with three divisions. The Department of Correction runs a 21 acre site at Grasslands in Valhalla holding a Jail Division, a Penitentiary Division and a Women's Unit, plus headquarters, a training centre and a maintenance building. For families it works as one place: one mailing address, one visiting policy, one phone vendor and one deposit system.
VisitationMen and women aged 18 and over. That covers people awaiting trial in Westchester County criminal courts, people serving sentences of a year or less, parole violators, and federal defendants with cases pending in the Southern District of New York. That last group is unusual for a county jail.
VisitationTo the person's name at PO Box 10, Valhalla, New York 10595. The county also runs a direct print service at westchestercountymail.com for colour photos, letters and greeting cards sent from a computer. Both routes are published by the Department of Correction itself.
Mail & PhotosBecause the county does not put everyone in it. Its own guidance says that for security reasons, or depending on the type of person held, someone may not appear at all. That makes an empty result genuinely uninformative here. The information line on 914-231-1000 can confirm custody, bail status and bail amount by phone.
Inmate SearchTouchPay, two ways. There are kiosks in the jail lobby serving both male and female residents, Monday to Friday from 9 AM to 9 PM, and the TouchPay website takes major credit cards at any hour. You need valid photo identification to leave money or property in person.
Send MoneyNo. The county states plainly that residents cannot receive phone calls or messages. Calls only go outward to a number you have set up to accept them. If there is an emergency or a death in the family, the route is to contact the shift supervisor.
Phone CallsYes, on a narrower schedule than most people expect. Packages for both male and female residents are taken Monday to Friday, 9 to 10:45 AM and 1:30 to 4:30 PM, and the window is shut between 10:45 and 1:30. The county publishes separate acceptable items lists for male and female residents.
Mail & PhotosAt the jail it is cash in United States currency or a major credit card, nothing else, and it can be done 24 hours a day, seven days a week. Bail can also be posted online or by phone with a major credit card. Any other form of payment has to go through the court of record instead.
