How to Send Money and Mail to Jefferson County Jail: Address, Money Orders, and Online Deposits
Getting a letter or money to someone at Jefferson County Correctional Facility is straightforward—but the rules are strict. Use the exact address format, send mail only through USPS, and stick to approved deposit methods so your loved one actually receives what you send.
Address inmate mail like this: (Inmate's full legal name) Jefferson County Correctional Facility 753 Waterman Drive Watertown, NY 13601 All mail must go through the United States Postal Service (USPS). The facility won't accept mail passed through a third party or handed over during visitation - everything needs to be mailed.
Heads up: Don’t decorate the envelope - no marks, drawings, stickers, or other adornments. All incoming mail is opened, logged, and inspected for contraband.
Sending contraband - any unauthorized item - is a violation of New York State Penal Law 205.20. It can lead to arrest, prosecution, and revoked visitation privileges. Staff open, log, and inspect all incoming mail. If you're unsure whether something is allowed, leave it out. Stick to plain letters mailed through USPS.
To add money to an inmate's commissary account by mail, send a USPS money order to the facility. The funds will be deposited into their commissary account. Like letters, deposits must go through USPS. Don't try to drop anything off or pass money during a visit - the facility won't accept it.
Do not send cash in the mail.
Jefferson County Correctional Facility also accepts online deposits through SmartDeposit. Your deposit goes to a processing center first, then gets forwarded to the facility. In most cases, funds are available within 1 hour.
Don't bring money to visitation expecting to leave it for your loved one - Jefferson County won't accept it. Use one of the approved options instead: mail a USPS money order, or make an online SmartDeposit transfer (funds typically arrive within about an hour).
Once a USPS money order is deposited, the facility gives the inmate a copy of the deposit receipt. That's the easiest way for them to confirm the money hit their account.
All incoming mail is opened, logged, and inspected for contraband when it arrives. This inspection is standard procedure and can affect how quickly mail and mailed deposits reach the inmate.
