Shipment option is not showing Box A & Box B for USPS?

[TheGoldenHeritage]

I am USA based Seller & I use USPS for my shipping. I most of the time use Box A & box B for reginal shipping but last week these options are missing . What to do to enable these options ? 

Thank You,

The USPS discontinued Regional rate shipping. You can still use the boxes until you use up your supply to ship regular Priority..just enter box size and weight. If it is an A box those usually qualify as a Priority cubic rate box if not a close zone where regular Priority is cheaper for that weight. Etsy doesn't offer priority cubic rates you'd need to use Pirateship or Shipstation etc.
