USPS Mail Growth Incentive
Lob is committed to helping you maximize your ROI by taking advantage of every opportunity to save on postage costs.
While many USPS programs are available, a primary focus for many of our customers is the USPS Mail Growth Incentive. This program offers 30% credit on incremental volume that exceeds your 2025 baseline in the form of a postage credit for use on future mailings, providing a powerful way to scale your outreach while lowering your bottom line.
How We Work Together
It is important to note that the USPS requires customers to sign up for the Mail Growth Incentive independently through the USPS Business Customer Gateway. However, you aren't in this alone. Lob is here to provide the support and insight you need to navigate the enrollment process, meet the program's requirements and ensure your mail volumes are reported accurately.

Registration Period
The Mail Growth Incentive registration for 2026 opens on March 1, 2026 and runs through May 31, 2026.
Mail Growth Incentive Requirements
Mail Owners must register under their own Mail Owners Customer Registration ID (CRID) assigned by USPS.
A CRID is a unique, USPS-generated numeric code, up to 15 digits, that identifies a specific business location involved in mailing activities.
If a Mail Owner does not have a CRID, one will be assigned during the USPS Business Customer Gateway account creation process.
It is incumbent upon the Mail Owner to ensure that the CRID(s) that they mail under are included and approved in their MGI registration and that all mailings that are entered are designated under their registered CRID in order to earn credits.
Mail Owners must mail a minimum of 1 million mailpieces in either the First-Class Mail or the Marketing Mail classes.
Aggregated volumes for both mail classes are not allowed when determining either the baseline volume or the over-achievement of volume.
Lob customers with a minimum volume of 800,000 annually AND have the potential to exceed 1,000,000 mailpieces annually in either First-Class Letters & Postcards or Marketing Letters are encouraged to register for the Mail Growth Incentive program.
Enrollment Process for 2026
Re-Enrollment for 2025 Participants
USPS enhancements to the 2026 Mail Growth Incentive program allows existing customer Mail Owners who participated in the 2025 MGI Program to automatically re-enroll via email.
Expect to receive the emails from the Mail Growth Incentive team beginning March 1, 2026.
💡If you participated in both First-Class and Marketing Mail Growth Incentive, you will receive separate emails for each. You must confirm the Baseline Volume agreement for each.
Confirm Baseline Volume
Mail Owners will need to confirm their baseline volume. The email from USPS will allow you to accept or dispute the reported volume.
Baseline volumes are separate for each First-Class Mail and Marketing Mail.
Below is an example of the email:
Upon agreement of baseline volume, the Mail Owner will receive an email confirmation of 2026 MGI program enrollment.

Monitor Reported Volume by Period
💡It’s important to monitor your reported volumes on a regular basis and alert the MGI team when reported volumes are not aligned with your mail volumes within each period.
Lob encourages our customers to provide screenshots of the reported actual volume each month to support issue mitigation prior to the Postage Credit Claim reporting period.
It is the Mail Owner’s responsibility to review volumes and alert the MGI team when Actual Volume is not accurate.
If your reported volumes are not aligned with Lob reported volumes during monthly check-ins, you must immediately open an inquiry ticket with the Ask Me team.
Refer to the Ask Me section for instructions on how to submit a ticket.
