If you're mailing the same light weight parcel to many different recipients, you can save hundreds or thousands of dollars in shipping costs by using one of USPS' services for shipping light weight bulk parcels.
That's because while other carriers typically price by the pound, USPS offers four different parcel categories priced by the ounce, so you don't pay for more than you are actually shipping. And, even if your package weighs almost a pound, these prices are still typically cheaper than other services' one-pound rates.
Here's what this page covers:
The main requirements to earn these low prices are simple: your labels need to be in a USPS-specified format with USPS-approved tracking barcodes, and you must upload a special "Shipping Services File" (SSF) to USPS before delivering your shipment to the post office.
The SSF contains the address, tracking code and other information about your parcels, so that USPS doesn't have to enter that information manually. That way, you'll be able to get electronic tracking information for each parcel on the USPS web site. Tracking is free for most bulk parcel services.
Our Postage $aver for Parcels software automatically creates labels in the correct format, and creates and submits the SSF file via secure transmission directly to USPS.
In addition to the categories of light weight parcels shown on this page, there are also bulk rates for Bound Printed Matter, which can weigh up to 15 pounds. Please see our Bound Printed Matter page for information and postage prices.
