Area code 747 is an overlay of the 818 area code in California’s San Fernando Valley, covering cities such as Burbank, Glendale, and Van Nuys. Introduced in 2009, the 747 overlay was necessary due to the rapid expansion of both residential and business telephone lines in the Los Angeles metro area. With the implementation of 747, ten-digit dialing became mandatory in this region. While 818 remains the more established identifier, 747 is increasingly common, especially among newer residents and businesses. The San Fernando Valley, known for its significant role in television and film production, remains a bustling cultural and economic hub. Area code 747, although newer, is now firmly embedded in the fabric of this creative and suburban area of LA.
