What marking is currently required on USPS Marketing Mail mailings?

The requirement for USPS Marketing Mail mailings is indicated by the marking "PRSRT STD." This designation signifies that the mail has been pre-sorted and meets the criteria for standard non-profit or advertising mail, which allows for bulk mailing at reduced rates.

Using "PRSRT STD" shows that the mail is prepared in accordance with USPS standards for pre-sorted mailings, which entails sorting the mail by zip code and other criteria to streamline delivery. This pre-sorting is designed to make the mailing process more efficient both for senders and for the Postal Service, allowing for faster processing and reduced costs.

Other markings, such as "USPS MARKETING," "PRE-SORTED MAIL," and "Bulk Mail," do not specifically indicate the pre-sorted status required for this class of mail in the same formal manner as "PRSRT STD." Therefore, for compliance with current USPS regulations, "PRSRT STD" is the correct marking to use for Marketing Mail.
