All properly addressed incoming regular mail will be processed and delivered unopened to the appropriate mail stops within one day of receipt by the mail centers.

Improperly addressed mail will be looked up and every effort will be made to determine a delivery destination. If a delivery point cannot be determined, it will be returned to the sender. If a return address is not available, the mail leader will open the envelope and determine if and where it should be delivered. If a delivery point cannot be determined, it will be disposed of in accordance with United States Postal Service and Department procedures.

All incoming controlled mail (certified, registered, or insured) will be processed and dispatched in accordance with United States Postal Services and Department directives at the end of each day. Controlled mail received after 3:30 p.m. will be safeguarded and processed for the next dispatch.

Outgoing registered mail is processed and dispatched under United States Postal Services approved combination lock or seal.
