USPS Mail Forwarding Timeline

The United States Postal Service (USPS) typically forwards First-Class mail for 12 months. After that period, mail that cannot be delivered to the original recipient will be returned to the sender.

How to Reduce Returned Mail

If you’re seeing a high volume of returned mail, consider cleaning your address lists using Letter Stream’s Deluxe Address Cleanup tool (NCOA).

Benefits of the Deluxe Address Cleanup Tool:

  • Helps ensure your mail reaches its intended recipient
  • Quick turnaround—typically takes less than 10 minutes
  • Identifies updated addresses for individuals who have moved within the last 18 months
  • Provides new addresses for those who have submitted an official Change of Address with USPS

By periodically cleaning your address lists, you can significantly reduce mail returns and improve delivery success.
