There are opportunities for savings when you mail presorted parcels at First-Class Mail, Standard Mail and Package Services rates. To qualify for discounted rates, you will need at least 50 pieces for Parcel Post, 200 pieces (or 50 pounds) for Standard Mail, and 500 pieces for First-Class Mail in a mailing. Your local Post Office or business mail entry unit can help you decide if mailing parcels is right for you. Also, there are parcel consolidators and other vendors who will prepare your parcels for you so that you could still take advantage of discounts without doing all of the work.

Remember, Presorted First-Class Mail and Standard Mail parcels require a barcode unless prepared in 5-digit containers. A surcharge would apply to all parcels that are not barcoded.

There also are automation rates for automation letters and cards and automation flats.
