- Alaska sends mail to each institution directly — address it to the prisoner's full name and offender number, then the facility's own mailing address.
- Include your full name and return address on the envelope.
- Incoming mail is opened and inspected for contraband before it is delivered to the prisoner (22 AAC 05.105–.660).
