People behind bars experience a spectrum of emotions, from regret to distress and anger to depression. There are many ways to alleviate emotional strain, including communicating with an incarcerated loved one.

Here are some ways to maintain communication with people behind bars:

Write to an Inmate

The First Amendment of the U.S. Constitution protects the right of prisoners to receive and send mail. Because of this right, anyone can contact an inmate inside a correctional facility by mail.

However, prison authorities inspect and open letters before handing them to the intended inmate. This inspection is done to prevent the entry of contraband into a correctional facility.

Mailing Addresses

Another thing to remember is that an inmate’s mailing address is generally different from the address of the facility. To avoid delays, you should include the following information when mailing an inmate:

  • Full name of the inmate
  • Inmate’s DOC (Department of Corrections) number
  • Institution name
  • P.O. Box housing (preferable)

Email Contact

Email is a faster way of sending letters to inmates. However, inmates or their loved ones can’t use mainstream email providers for this form of messaging.

Corrlinks is the company that manages TRULINCS (Trust Fund Limited Inmate Computer System). This new system provides inmates limited computer and internet access, including email communication provisions.

Phone Contact

The correctional facility also provides phone access to inmates. However, calls are regulated and may be monitored by prison authorities.

Inmate Phone Procedure

Correctional facilities heavily regulate inmates’ access to and use of phones. Because of this, inmates must provide a list of numbers to be approved, which an inmate can use to place collect calls.
