The number coding scheme — officially the Unified Vehicular Volume Reduction Program (UVVRP) — is the MMDA's traffic management policy that restricts vehicles from using major roads on specific weekdays based on their license plate's last digit. Understanding the scheme helps Filipino drivers avoid ₱300 fines and plan their daily commute.
Whether you're a new driver preparing for the LTO practice test or a seasoned motorist, this guide covers the complete MMDA number coding schedule, covered areas, coding hours, exemptions, and what to do on suspension days.
The MMDA number coding scheme — also called the Unified Vehicular Volume Reduction Program (UVVRP) — 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. Practice with the free LTO - Exam Reviewer practice test on PracticeTestGeeks (600+ questions with answer explanations).
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 — 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.

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, España 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.
| Pros | Cons |
|---|---|
| LTO has a defined, publicly available content blueprint — candidates know exactly what to prepare for | The scope of tested content requires substantial preparation time that competes with existing professional or academic commitments |
| Multiple preparation pathways (self-study, courses, coaching) accommodate different learning styles and schedules | No single resource covers the full content scope — candidates typically need multiple study tools for comprehensive preparation |
| A growing ecosystem of study resources means candidates at any budget level can access quality preparation materials | Test anxiety and exam-day performance variability mean preparation effort does not always translate linearly to scores |
| Clear score reporting allows candidates to identify specific strengths and weaknesses for targeted remediation | Registration, preparation, and potential retake costs accumulate into a significant financial investment |
| Professional recognition associated with strong performance provides tangible career and academic benefits | Content and format can change between exam versions, making older preparation materials less reliable |
