Overview
- Mexico City’s environment secretariat published the January–June 2026 calendar in the Gaceta Oficial, assigning two‑month windows by sticker color and plate ending.
- CDMX schedule: yellow (5–6) in January–February, pink (7–8) in February–March, red (3–4) in March–April, green (1–2) in April–May, and blue (9–0) in May–June.
- Edomex released its first‑semester 2026 calendar with similar sequencing, detailing windows from January 2 to June 30 by engomado and plate termination.
- Edomex granted a one‑time extension to January 15, 2026 for vehicles with plate endings 9 or 0 that missed the second‑half 2025 check, citing high demand, Hoy No Circula impacts, and hologram supply issues; walk‑ins are permitted.
- Verification remains mandatory with sanctions for late compliance, and the current CDMX fee is reported at 738 pesos, which may change after the UMA update later in January.
