LTO Number Coding Scheme Philippines: Complete Guide 2026 October
Prepare for the LTO Number Coding Scheme Philippines: π certification. Practice questions with answer explanations covering all exam domains.

What Is the Number Coding Scheme?
The MMDA number coding scheme β also called the Unified Vehicular Volume Reduction Program (UVVRP) β was launched in 1995 to reduce traffic congestion on Metro Manila's major thoroughfares. Each weekday, vehicles with license plates ending in specific digits are prohibited from using covered roads during peak hours.
The restriction is based on the last digit of your vehicle's license plate. This applies to both private and public utility vehicles that fall under the MMDA's coverage area. Before you get behind the wheel, it's worth reviewing your plate number carefully β many motorists unknowingly violate the scheme and receive apprehension tickets.
Knowing the number coding rules is also tested in the official LTO driver's license examination. Our LTO practice test includes sample questions on traffic regulations including the coding scheme, helping you pass on your first attempt. For a broader overview of traffic rules and requirements, check our LTO complete guide.
Coding Hours and Covered Areas
The number coding restriction is enforced from 7:00 AM to 8:00 PM, Monday through Friday. The scheme covers major roads, avenues, and expressways within Metro Manila that fall under MMDA jurisdiction. Key roads include EDSA, C-5, Commonwealth Avenue, Quezon Avenue, EspaΓ±a Boulevard, Taft Avenue, and Roxas Boulevard, among others.
Not all cities in Metro Manila apply the MMDA coding in the same way. Some Local Government Units (LGUs) such as Makati, Pasig, and Mandaluyong have their own supplemental coding ordinances that may extend hours or cover additional roads within their jurisdiction. Always check local city ordinances in addition to the MMDA baseline rules.
If you're renewing your license or registering a new vehicle, understanding road restrictions is essential. Visit our LTO license renewal guide and review the TPL insurance requirements before your next LTO appointment. You should also familiarize yourself with Philippine road signs that indicate coding restriction zones.
