Map & officials sources
Regional boundaries: Philippines JSON Maps, with Negros Island Region updates. District directory: Wikipedia. Regional geometry is simplified from 2023
boundary data, with Negros Island Region and Sulu’s transfer to Region IX applied. Districts use the
2025 congressional directory; city and municipality listings are compiled from district articles
and the PSGC index. Official records use the DILG 2025–2028 directory (February 2026), current
congressional and governor directories, and later reports linked on each card. Compiled
September 18, 2026; this is a dated directory, not a live government feed. Office changes may
occur after each source date. Portraits link to their source and are shown where available.
Province maps group the locality boundaries by province, separating independent cities under RA 7160, Section 29. Administrative and congressional boundaries may differ. District map shapes combine 2023 municipal boundaries with NAMRIA / DPWH district geometry (March 2022), updated
for the listed constituencies. Caloocan uses RA 11545 and Taguig’s EMBO allocations follow
COMELEC Resolution 11069 (2024). Boundaries are simplified and illustrative; a district within
one city displays only its part of that city. An independent geographic explorer, not an
official government service.
