A permanent forward is an important postal service document that facilitates the forwarding of mail from one address to another. The correct period for which a permanent forward is kept on file is 18 months. This duration allows postal officials to manage and process mail efficiently while ensuring that individuals who have permanently changed their addresses do not miss important correspondence.

After 18 months, the forwarding service is considered obsolete, as individuals are expected to set up mail at their new address permanently. Keeping the data on file for this length of time helps minimize the chances of mail being misplaced and supports a smooth transition for mail delivery during the period of adjustment after a move. This protocol is crucial for maintaining effective communication and reliable service within the postal system.
