The Hidalgo County Sheriff's Office operates the Hidalgo County Detention Center in Edinburg, the county seat. The facility processes bookings from the sheriff's office and numerous municipal police departments across the county, including McAllen, Edinburg, Mission, Pharr, Weslaco, and others. With nearly 870,000 residents and over 20 incorporated cities, Hidalgo County's detention system handles a substantial volume of bookings. Records, including booking photographs, charges, and bond information, are publicly accessible under the Texas Public Information Act (Tex. Gov’t Code Ch. 552).

Hidalgo County's position along the U.S.–Mexico border gives it a unique law enforcement landscape. The county shares the international boundary with the Mexican state of Tamaulipas, with several international bridges connecting Hidalgo County cities to their Mexican counterparts. Federal agencies including U.S. Customs and Border Protection, Immigration and Customs Enforcement, and the Drug Enforcement Administration maintain a significant presence in the county, though federal bookings are processed separately from the county jail system.
