Using facility, release window, and age filters
Filters shrink the public roster to the segment you intend to write—then you purchase that result set.
What you can filter
Typical controls include age range, sex, projected release window, and facility (among options available in your dashboard). Combine filters carefully: each constraint reduces the matching count.
Facility lag
Public BOP roster data can trail real transfers. A name may still show a prior facility until the roster refresh catches up. Treat facility filters as planning aids, not guaranteed current location.
Release windows
Release-related fields are planning data from the roster. Confirm anything time-sensitive against official sources when it matters for your purpose.
FAQ
Why did my count change between visits?
The underlying roster refreshes. Filters that matched last week may return a different count after an update.
Can I target one institution only?
Yes—use the facility filter in the builder when you need a single-site list.
