For how many months are permanent change of address (COA) requests kept on file?

Permanent change of address requests are kept on file for a total of 18 months. This retention period serves multiple purposes, such as ensuring the accuracy of mail forwarding and allowing sufficient time for adjustments in the mailing system. After this period, the records are typically purged to maintain streamlined operations and data management within the postal service.

Understanding the timeframe for how long these requests are maintained is important for both customers and postal service employees, as it relates directly to mail delivery accuracy and customer service. Knowing that the records are kept for 18 months helps employees manage customer inquiries regarding their change of address and facilitates their understanding of potential delays or issues related to mail delivery during that period.
