What is USPS Flat?
Simply put, USPS flat is flat sized mail.
- Not Larger than 12″ x 15″
- Not more than 3/4 Inch Thick
- Flexible
- Uniformly Thick
Many items that are shipped as parcels in polybags, bubble mailers, or boxes could qualify for USPS Flat Mail rates with the right packaging.
Why Best Mailers qualify as USPS Flats, and other packaging options don’t
Polybag
Poly bags allow contents to shift from side to side. Poly Bags do not stay flat, or have a uniform thickness. Poly Bags do not qualify for USPS Flats and must ship as Lightweight Parcels.
Too Thick and Rigid. Boxes don’t offer the flexibility required for USPS Flat. Boxes must ship as lightweight parcels.
Box
Bubble Mailer
USPS Flats must be less than ¾” thick. Bubble mailers add unnecessary thickness, and do not stop contents from shifting. Does not qualify for USPS Flat-rate mail.
Designed to start flat and stay flat. These mailers do not expand to fit garments and are difficult to keep merchandise flat while inserting.
