Priority Mail | USPS
Use our Priority Mail Flat Rate Envelopes or Boxes that come in standard sizes so you don't have to worry about measuring them.
So what boxes are you able to use when shipping with usps? Can you use priority mail boxes or can you use the priority boxes that say flat rate on them ? I’m confused what type of usps boxes are allowed
You can use both kinds of priority, just not Express. There should be a stickied post in this sub with a letter in case they give you a hard time. The mailing label also has a statement on there that the worker can read. Otherwise just stick it in the drop box. Regardless, red priority is allowed, not blue. More on reddit.com
