What type of parcel is classified as having a girth plus length of 108 inches or less?

The classification of a parcel as having a girth plus length of 108 inches or less pertains specifically to Priority Mail. This standard reflects the maximum dimensions for parcels that can be sent using this service, allowing for efficient handling and processing within the USPS system. Priority Mail is designed for timely delivery and includes features such as tracking and insurance, which are advantageous for customers looking to send parcels quickly and securely.

Express Mail, on the other hand, typically has stricter requirements regarding size but focuses more on speed and delivery guarantee rather than the specific girth and length measurements. Standard Mail generally applies to bulk mailing options that prioritize weight and costs over size, while Package Services includes a broader range of options without these specific dimensional constraints.

Understanding the size and classification is crucial for sending parcels correctly within the postal system. In this case, the definition and limitations of Priority Mail make it the correct choice for parcels with a girth plus length of 108 inches or less.
