# State flags of Mexico

Most Mexican states do not have an official flag. For these states, a de facto flag is used for civil and state purposes. State flags of Mexico have a 4:7 ratio and typically consist of a white background charged with the state's coat of arms.
At least fourteen states have official flags: Baja California Sur, Coahuila, Colima, Durango, Guanajuato, Guerrero, Jalisco, Oaxaca, Querétaro, Quintana Roo, Tabasco, Tamaulipas, Tlaxcala, and Yucatán. Except for those of Guanajuato, Jalisco, Tlaxcala and Yucatán, each official flag is simply a white background charged with the state's coat of arms.
Two states have provisions in their constitutions explicitly declaring that there shall be no official state flag, Baja California and Campeche.
