ZIPping through Long Beach: Today, 90806, the ZIP that Wrigley built • Long Beach Post News
The 90806 ZIP code is filled almost exclusively with the various Wrigley neighborhoods—North and South Wrigley, Southeast Wrigley and Wrigley Heights, all spun off from a small tract developed in the late 1920s through mid-1930s by chewing gum magnate William Wrigley.
