The United States Postal Service introduced a test allowing "repositionable notes" (for example, 3M's Post-it notes) to be attached to the outside of envelopes and bulk mailings, afterwards extending the test for an unspecified period. The repositionable note may be fixed directly to the address side of First-Class Mail and Standard Mail letter-size mailpieces. These mailpieces must meet the standards in 7.2 through 7.6. The note is included as an integral part of the mailpiece for weight and postage rate and must be accounted for in pricing.
