Is ZIP code 83638 safe? Honest data snapshot

ZIP code 83638 sits within Valley County, ID. The figures below are the county's own FBI UCR numbers for 2024, the most accurate available statistic for this location, not a ZIP-specific calculation.

Valley County reported a violent-crime rate of 153 per 100,000 residents and a property-crime rate of 468 per 100,000 in 2024, drawing on county-level agency submissions.

Based on just 18 reported violent incidents across a county population of 11,746, this count is too low to support a reliable per-100K rate comparison. It may reflect a genuinely low-crime county, or it may reflect incomplete agency-level reporting to the FBI UCR Program for this county and year, small county-level counts are common in FBI Table 10 and should be treated as a data point, not a precise safety ranking.

ZIP 83638 carries a Census-reported population of 7,410, ranking #1 of 4 ZIPs in Valley County, spread across 668.4 square miles (about 11 people per square mile). For a full breakdown of Valley County's crime categories and year-over-year trend, see the Valley County crime page linked below.
