  • openFDA Device Enforcement Report-date coverage June 20, 2012–July 08, 2026 Known gap: openFDA describes 2004-present coverage, but the current export has no report-date records in this interval.
  • openFDA Device Recall event_date_initiated coverage June 01, 1997–June 30, 2026

Enforcement coverage uses report dates; product initiation dates can precede those bounds. Device-enrichment coverage uses FDA event_date_initiated.
