can you use usps flat rate boxes for priority mail

Priority Mail Cubic is available only to shippers with Commercial pricing – so you won’t be able to get this rate at the Post Office window (Retail) – but in July of this year, it became available via Commercial Base, so no longer just for higher volume shippers. ShipStation had compared the various flavors of Priority Mail in a post from July.Ī post from Shippo earlier this year had pointed out that USPS Priority Mail Cubic pricing had always been cheaper than Regional Rate – but said that in 2022, Regional Rate had become more competitive – frustrating, since now Regional Rate is going away. The USPS website explained that Regional Rate Boxes A and B were best used for small, dense packages being shipped short distances.

That means sellers will have to look for alternative shipping services and supplies, with sellers probably looking first at Priority Mail (Flat Rate, Standard, and Cubic) to compare rates. The US Postal Service confirmed it would no longer be making Regional Rate-sized boxes available to shippers once it does away with the service in January.
