Type of Mail Allowed for Jefferson County Jail & Sheriff
The Jefferson County Jail & Sheriff allows inmates to receive pre-metered postcards like the type purchased from the post office. They may also allow certain photo postcards as long as they have not been tampered with or contain images that may be considered to be obscene or violent in nature.
The Jefferson County Jail & Sheriff may also allow regular postcards and envelopes to be mailed to inmates as well, however more and more jails are no longer allowing envelopes due to concern about paper being dipped into liquefied drugs like methamphetamines and cocaine and then mailed into secure facilities.

Books must NOT contain images or content that are considered excessively violent, pornographic or obscene. Any book that does not meet the Jefferson County Jail & Sheriff standards will be disposed of.
Hard cover books will not be accepted by the jail due to their potential to be used as a weapon.

Important Mail Tips
Mail is always scanned and inspected for contraband, obscenity and other rule infractions.
Assume that everything you write will be read by jail staff and can and will be used against you or your inmate in court.
Never write anything about the inmate's court case you wouldn't want read aloud in court.
Mail is considered by the jail to be a privilege. Any violations of the mail policies can result in the inmate's mail privileges being suspended.
The introduction of contraband by you into the jail through the mail could result in criminal charges being filed against both you and the inmate.
