Letters to Cape Vincent go to P.O. Box 599, Cape Vincent, NY 13618-0599. There is one box and no separate family box, so the address is simple. The thing to avoid is the street: map listings give State Route 12E with a different ZIP, and letters belong at the box. Everything else here is standard New York practice, and the paper you send is the paper they hold.

Name and DIN together on the first line. The DIN is the Department Identification Number the state lookup returns, and mail without one cannot be sorted to a person.
Many New York prisons publish a business box on the address line and a separate family box in brackets beside it. Cape Vincent does not. NYSDOCCS lists the address as 36560 State Route 12E, P.O. Box 599, Cape Vincent, NY 13618-0599, and P.O. Box 599 is the box for family mail as well.
Search for Cape Vincent Correctional Facility on a map and you get 36560 State Route 12E, often with a ZIP+4 that is not 0599. That is the right place to travel to and the wrong line to write on an envelope.

Published by the department and applying statewide.

| Nude photographs | |

There is also a paper limit: five pages of printed or photocopied material per letter, with newspaper clippings counting one page each. Legal papers for an active case can exceed it only with the Superintendent’s written permission, obtained in advance, and no more than once every four months.
Ordinary printed photographs get through and they are the best thing you can put in an envelope.
Polaroids do not, anywhere in New York, because of the format and not the picture. An instant print has a thick backing that can conceal things, so the category is excluded.
Order prints from a photo service or print them at home on ordinary photo paper, and keep writing on the back to a name and a date.
Nothing financial goes in the envelope. The inspection is looking for exactly that.
Deposits go to the JPay lockbox, PO Box 531190, Miami, Florida 33153, with a JPay deposit slip, capped at $999.99 per money order and free by post. On a visit day the lockbox inside Cape Vincent takes $50 in cash a day in total.
Families cannot post or carry packages in. Everything arrives directly from an approved vendor by USPS, FedEx or UPS.
The allowance is two non-food packages a year and three food packages a month, food capped at a combined 40 pounds. The department publishes a disapproved vendor list and Directive #4911 carries the detail.
Mail from a lawyer or a court is privileged under Directive #4421, and it is opened in front of the person it is addressed to, not in the mailroom.
A family member cannot send ordinary mail under a legal label. Trying it puts the letter at risk instead of speeding it up.
Cape Vincent is open every weekend but sits a long way from most of the state, so for most families the post carries the weeks between visits.
Pigeonly prints and sends letters and photos to Cape Vincent with P.O. Box 599, the full ZIP and the DIN already in place, so the envelope goes to the box and not the road.
