 Not all city of Houston residents have "Houston, Texas" mailing addresses since the USPS does not base its mailing address names on actual municipal boundaries; some have Friendswood, Humble, Kingwood, Missouri City, and Stafford postal addresses.After the 1996 annexation of Kingwood, residents retained "Kingwood, Texas" mailing addresses, and some places in the city limits before the annexation had Kingwood mailing addresses.Residents of several other municipalities, including Jacinto City, Jersey Village, Nassau Bay, and West University Place, have "Houston, Texas" mailing addresses, and some residents of Missouri City also have Houston mailing addresses.
