Postal Service records are grouped into record series. A record series is a group of records that relate to the same subject and have the same retention period. A record control schedule provides for all aspects of records management for a record series including storage, transfer, retention periods, and disposal instructions. All records control schedules will specify a cutoff period. A cutoff period is the termination of a file or information in a file at regular periodic intervals that allows for their disposal or transfer.
