Mailing Money

Benton County Jail will accept:

  • US postal money orders
  • Western Union Money Orders
  • Cashier’s Checks
  • US Treasury checks
  • Checks from Tribal institutions
  • Checks from other correctional facilities

Social Security, SSI, and unemployment checks will need to be verified with the appropriate department. If verified, the check will be placed into the inmate’s property. If requested by the verifying department, the checks will be returned to that specific department as the inmate is not eligible for funds. These checks will not be posted to the inmate’s account.


Any other checks or cash will be returned to sender.
