Us Postal Service Flat Rate Padded Envelope - Global Network
If it fits, it ships ®.
Jul 24, 2026
If it fits, it ships ®. When sealing a flat rate box or flat rate envelope, the container flaps. Padding doesn't automatically mean parcel.
Understanding the Context
Follow the sop, measure the thickness, width, check for any variations in thickness, etc. But no, padding =/= parcel. I was told if it passes through. This padded envelope is a great choice for shipping at the low flat rate price.
