Please note that Sugar Land has three zip codes (77478, 77479 and 77498) and you should perform searches on all three when requesting a search by area. The Department of Public Safety (D.P.S.) website does not differentiate between the Sugar Land Police Department and the Fort Bend County Sheriff's Office. The search on these zip codes will produce a list of offenders from both departments. The Sugar Land Police Department is responsible for only those living inside the city limits.
