When must the card file be purged?

The card file must be purged during the first five days of the 13th month to ensure that the information contained is current and relevant. This timing allows for the organization of data that aligns with monthly cycles, facilitating better record-keeping and resource management. Purging the card file at this specific time helps in maintaining efficiency within the mail processing system by removing outdated or unnecessary entries, thereby streamlining operations for the following month.

This practice also aligns with standard administrative procedures that focus on keeping information up-to-date, which is crucial for accurate mail delivery and customer service. By doing the purge in the first five days of the 13th month, it allows for a clear transition into the next cycle without the risk of carrying over irrelevant data.
