Timeframe. The United States Postal Services reports that as of January 2011, it takes an average of one to three days for First-Class Mail to arrive at its destination. Priority Mail takes an average of one to two days to arrive, according to the USPS. USPS only includes the time a package stays in transit in their estimations. Packages dropped off at a post office during business hours usually leave that day. Packages dropped off after hours may take an additional day.
Priority mail should take between one to three days to arrive. This is not a guarantee delivery time frame by USPS. If you want a guaranteed delivery time frame then you have to opt for one of the other delivery services from USPS. Many times paying for the Priority Express wonât get your package there any faster either.
