702 (pronounced "Seven-O-Two"), named after the area code of their hometown of Las Vegas, Nevada, is an American platinum-selling R&B trio. Originally a quartet, the group became a trio, which includes sisters Irish (born June 2, 1980), and LeMisha 'Misha' (born June 10, 1978) Grinstead, and lead singer Kameelah 'Meelah' Williams (born March 8, 1978). Irish's twin sister Orish Grinstead (June 2, 1980 – April 20, 2008) was founding member and later a substitute vocalist.

In Las Vegas, sisters LeMisha and Irish Grinstead, and their friend Kameelah Williams, were students at the Las Vegas Academy of Performing Arts. Irish, her twin sister Orish, and LeMisha occasionally sang in the lobby of Caesars Palace where they were discovered by actor/comedian Sinbad. He visited their home in order to convince their parents to send the trio to Atlanta for a convention and music competition. Though the girls missed the deadline for entry, Sinbad used his name to get them in. "Sweeta than Suga," as they were then called (Sinbad suggested the name), came in second in the competition. As the convention was nearing a close, they met Michael Bivins (formerly of New Edition and Bell Biv DeVoe) who agreed to work with the sisters. They were briefly joined by their cousin Amelia Childs. After they made their recorded debut on Subway's hit single "This Lil' Game We Play", Amelia dropped out of the group and was replaced by Kameelah Williams. After recording a few demos as a quartet including "Steelo", and "Get It Together", Orish decided to leave the group (even though her vocals appear on the first album). Bivins continued to work with different producers and songwriters to get the right feel for their first album. The reconfigured group was christened "702," which is Las Vegas' area code, a name which Bivens suggested.

Year 702 (DCCII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. The denomination 702 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
