A first-class sent letter from Ft. Benning, Ga., to Ohio typically takes three days, according to the U.S. Postal Service. The USPS does not guarantee that time frame. First-class mail is up to 13 ounces and costs 49 cents as of July 2014.
A USPS map server allows users to input the origination point, while a map displays normal delivery times for one day in blue, two days in red and three days in green. Every point in Ohio, except for extreme southern Ohio, shows three days for a normal delivery time for first-class mail. The three-day delivery is from the time the envelope is postmarked.
