Metro Manila number coding (UVVRP) follows MMDA rules where coding is enforced from 7:00–10:00 AM and 5:00–8:00 PM, with window hours allowing vehicles on the road from 10:01 AM–4:59 PM and 8:01 PM–6:59 AM the next day; however, Makati City applies stricter number coding from 7:00 AM–7:00 PM with no window hours, and some cities or specific roads may have different rules, so drivers should always check local advisories, while exempted vehicles such as public utility vehicles, ambulances, media vehicles, provincial buses, and essential goods carriers are generally not included.
