Final answer:
Outgoing mail from prisoners must include the recipient's properly formatted address and a clear subject line. Depending on the facility's regulations and the law, additional sender identification may be required.
Step-by-step explanation:
When a prisoner sends out any outgoing mail, they must include specific information to ensure the mail is processed correctly. The information required on outgoing mail includes the recipient's address, which should be left-justified and include the recipient's name, street address, city, state, and zip code. If writing to an international address, the country should be written in capital letters on a separate line following the other address details. It is also important for the sender to include a clear and specific subject line that can easily reference the contents of the mail at a later date. If the letter is directed to someone within a company, the company name should be included. Additionally, the mail must adhere to any regulations set by the correctional facility, which might include identifying information of the sender-prisoner.
