Overview
- Mexico City’s environment secretariat published the January–June 2026 schedule in the official gazette, assigning verification by engomado color and plate ending.
- The order is 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 authorized a single extension through January 15, 2026 for vehicles with plate endings 9 and 0 that missed the second‑semester 2025 window.
- The extended Edomex checks must be done directly at CVECA, preferably without an online appointment, under the same tariffs and requirements, with fines applying for noncompliance.
- Verification remains mandatory in CDMX, exemptions apply for valid Doble Cero/Cero and eligible electric or hybrid vehicles, and the current 738‑peso fee tied to the UMA may change after INEGI’s late‑January update.
