Mail is classified as bulk when
- There are at least 200 pieces of mail or it weighs 50 pounds.
- Pieces weighing less than 16 oz each of identical mail.
- All are going out at the same time
Bulk Mail has two ways of charging postage, the indicia (permit box), which is printed in the upper right-hand corner on the piece, or metering, which means printing the postage on each piece by a meter machine.
Please keep in mind that Bulk Mail is not first class mail and it may take extra time to get through the mail.
Normal processing is 2-3 days unless you have a very unique or large job. Mail Services must be made aware of any bulk mail shipments of greater than 5,000 pieces in order to ensure the order can be processed at the USPS.
