In order to write a letter to someone in jail, one must know the inmate's full name, his housing unit and his booking number at the detention facility in which he is housed. Upon constructing the letter, one should keep in mind that all letters are scanned for issues regarding security and safety. Letters are also inspected for contraband.
Writing a letter to someone who is incarcerated is a great way to establish or maintain a connection, considering the low cost. Inmates are provided with a small supply of pre-stamped envelopes, but additional stamped envelopes must be purchased. When writing a letter to an inmate, it is important not to include any sensitive information that the letter's recipient would not want to be seen. All letters are inspected, unless they are addressed to or from the inmate's attorney. Proper language should be used. No code or secret messages are allowed. If such are discovered, the letter is returned to the sender. Letters that include photos depicting nudity or drawings of nude figures are not accepted at prisons. Checks, personal items or envelopes that could contain contraband are not accepted. Detention facilities maintain the right to refuse any correspondence, except legal correspondence.
