Mail owners participating in the 2026 Mail Growth Incentive should establish a process for tracking postage and mail volume, regularly monitoring USPS-reported volume, and taking advantage of available claim windows. Doing so can help ensure earned credits are properly captured and claimed. 

Key takeaways

  • Reconcile your mailing activity monthly.
  • Regularly monitor USPS-reported volume within the Mailing Promotions Portal for each Customer Registration ID (CRID) associated with your Service Request Number (SR#).
  • Expect some differences between your internal reporting and USPS totals because the Postal Service performs its own reconciliations and audits throughout the year.
  • Credits may be claimed beginning in July, again in October, and finally during the January through February reconciliation period.
  • Any unclaimed 2026 Mail Growth Incentive credits are forfeited after February 28, 2027.

Why ongoing tracking matters

Accurate tracking and reconciliation are essential to making the most of the 2026 Mail Growth Incentive. Reviewing performance on a regular basis can help identify reporting discrepancies before they become larger issues later in the year.

Best practices for managing your Mail Growth Incentive activity

To help ensure accurate reporting and successful credit claims, consider the following best practices: 

  • Reconcile your mailing activity monthly.  

  • Regularly monitor USPS-reported volume within the Mailing Promotions Portal for each CRID associated with your SR#.  

  • Expect some differences between your internal reporting and USPS totals. USPS performs its own reconciliations and audits throughout the year.  

  • If, by the fourth quarter, discrepancies exceed your acceptable tolerance, submit an inquiry through the Mailing Promotions Portal from within the applicable SR#. Include supporting documentation to help expedite the review.  

Establishing a regular review process throughout the year can help minimize surprises and make the final reconciliation process more manageable.
