At minimum you will need a first and last name. If you can provide the middle name or initial that is even better. In a perfect world you will also have the inmate's birthdate, but if not, an estimated age will help.
If you are not sure what county jail the inmate is located in, it helps to at least know the geographic area. Knowing what state the inmate is in is good; knowing which county is even better.
