Changes Coming in January for USPS Direct Mail Requirements

There are some direct mail changes on the horizon that will affect most mailers so make sure you bookmark or print this post.

These definitely aren’t MAJOR changes, but they will require some tweaks for most companies. Your direct mail vendor should be able to guide you in the right direction.

Effective January 5, 2013, the USPS is changing some of the requirements for direct mail to qualify for automated rates.

The following is a summary of what could affect your campaigns:

  • The maximum size for a letter size self mailer will change from 6-1/8″x11-1/2″ to 6″x10-1/2.
  • For self mailers, the folded edge now must be at the bottom (previously it was preferred). Otherwise the piece will be charged non-machinable rates (.20 extra per piece).
  • For non-booklet self mailers, there must be a minimum of 2 tabs or glue spots in order to qualify for automated rates.
  • For pieces over 1 oz. in weight, 1-1/2″ wafer seals must be used. For pieces under 1 oz., the rules will not change.

If you have any questions pertaining to these changes, please contact us.

Hi Jim, thanks for pointing that out. I added clarification to the blog post. The 3 tab requirement is for booklet self mailers only.
