Don't Overstuff Priority Mail Envelopes, Says USPS

Author: Renee Bingling

It may be very tempting during the holidays to overstuff your Priority Mail® envelopes, as after all the Post Office™ says “if it fits it ships”, right? That is quite a bit of a stretch of the Priority Mail catchphrase. The U.S. Postal Service® is reminding holiday shippers to resist the urge to turn Priority Mail Flat Rate envelopes into “kangaroo pouches” by overstuffing them – even if the envelope can be sealed.

The USPS is encouraging employees to remind customers that manipulating or reconfiguring a Priority Mail Flat Rate Envelope by exceeding its capacity won’t help them save money. Although the packages can be accepted, they will be weighed and zoned accordingly using the regular Priority Mail price instead of the flat-rate charge.

The Postal Service’s regulations note that tape may be used on the flaps and seams to reinforce the container “provided the design of the container is not enlarged by opening the sides and the container is not reconstructed in any way.” This simply means that a small bulge is ok, but an overstuffed envelope isn’t.

Not true! There is currently no maximum thickness for a flat rate envelope and you all need to immediately refer to the official post office Bulletin titled DMM notice proper use of flat rate containers...,

We recommend using good judgement when stuffing a FRB. While it isn't exactly clear how far you can push it, there is some leeway regarding the size of the bulge, the USPS does reserve the right to charge extra or to ask you to repack in a larger box.

USPS has a cardboard display with a 1/4" slot as a guide. But what is considered too full to pass through that slot? Should the envelope slip through without and friction? Slight friction? Or should it be based on how many sheets are folded within the evelope: 16 pages folded in half equivalent to 3 oz, or 8 pages trifolded? Clarification on the details would be great.

If it slips through rather easily you should be okay. If you have to force it through, you run the risk of incurring extra charges.
