Package Services and Standard Post
Package Services is a collective term used for the three classes of mail described below which are primarily intended for specific items. There are three subclasses of Package Services (see below). Each subclass is best suited for a certain kind of mail, so be sure to pick the one that best suits your mailing.
Standard Post (formerly Parcel Post) is primarily intended for shipping merchandise and includes USPS Tracking/Delivery Confirmation at no additional charge. Standard Post is available through retail channels and is primarily intended to be presented at a USPS retail service counter where USPS Tracking/Delivery Confirmation service can be initiated.
Package Services and Standard Post mailpieces do not receive expedited service. Package Services and Standard Post do not include free forwarding and return, but mailers can use ancillary service endorsements to tell the Postal Service how to treat undeliverable mail.
Unendorsed Package Services or Standard Post, mail that is refused or is otherwise undeliverable will be returned to the sender marked "postage due", except for Bound Printed Matter. Unendorsed, undeliverable Bound Printed Matter is disposed of at the local Post Office.
You can enhance the service and convenience of Package Services by adding extra services such as insurance and USPS Tracking/Delivery Confirmation. These services are available for a small fee.
Lower postage prices are available for bulk quantities of Package Services that meet additional standards for volume, presort, and destination entry.
If you are mailing merchandise, compare the costs and service between Priority Mail and Standard Post. In some cases, the postage costs are very similar to Priority Mail but Priority Mail travels there faster and includes free forwarding and return.
