Quick Answer. The United States Postal Service offers two regular mail delivery services, First Class and Standard Post. First Class mail is typically delivered within one to three business days, depending on the location. Standard Post is typically delivered within two to eight business days.
First-Class Mail includes letters, postcards, large envelopes (called flats), and small packages, providing each piece weighs 13 ounces or less. First-Class Mail is processed by the USPS with the highest priority. It goes to the front of the line; ahead of the other classes of mail. Locally, First-Class will typically be delivered within one to two business days, and nationally it will be delivered in three business days.
