A SAFPF sentence in Texas is not the same as a traditional prison sentence, though it is managed within the TDCJ system. SAFPF stands for Substance Abuse Felony Punishment Facility, and it is an intensive in-prison drug treatment program for felony offenders whose substance abuse is directly tied to their criminal behavior. Participants live in a structured therapeutic environment and complete a treatment curriculum rather than doing general population time. It is still incarceration, but the program is treatment-oriented rather than purely punitive.
TDCJ determines which SAFPF facility an inmate is assigned to based on bed availability and intake scheduling rather than proximity to where the inmate is being held. There are several SAFPF units within the Texas system, but you generally cannot request a specific location. The state places inmates where space exists at the time of transfer.
On the 2282 number: without more context, that is not a sentence length. It could be a penal code reference, a case number component, or something related to court costs or restitution. His attorney or the Wichita Falls county court clerk can give you the specific explanation for what that notation means in his paperwork.
Once he is placed and you have his TDCJ number and facility, InmateAid can help you locate him and set up communication.
