priority mail how long
HOW LONG DOES PRIORITY MAIL TAKE? In a nutshell, the USPS flat rate delivery time ranges from 2 to 5 days. The factor that will most influence whether your package is received in 2-3 days, or 3 â5 days isnât the weight, its the shipping zones. The weight restriction on Priority Mail is in place to eliminate that as a concern for shipping delays.
