Postal officials say the agency is releasing a stamp featuring Ray Charles, of Albany, on Monday along with one of the artists' previously unreleased songs.
Charles was a singer and songwriter who pioneered the soul and rhythm and blues genres. He died in 2004.
Events are being planned in Atlanta and Los Angeles to celebrate Charles' induction into the series.
R&B singer Ashanti and the Morehouse Glee Club are scheduled to perform at the school's Ray Charles Performing Arts Center, and Chaka Khan is headlining an event at the Grammy Museum at L.A. Live.
The U.S. Postal Service honors music legends annually by featuring them on limited-edition stamps.
