Every vehicle on Indian roads — from scooters to luxury cars — carries a unique identity known as the vehicle registration number plate. But have you ever wondered what those combinations of letters and numbers actually signify? They’re not random — in fact, they tell an entire story about the vehicle’s origin, registration, and category. Let’s decode it together!

🚘 1. The Structure of an Indian Number Plate
A standard Indian vehicle number plate typically follows this format:
AA 00 AA 0000
Here’s what each part represents:
- First Two Letters (State/Union Territory Code)
These letters indicate the state or union territory where the vehicle was registered.- Example:
- MP – Madhya Pradesh
- MH – Maharashtra
- DL – Delhi
- KA – Karnataka
- Example:
- Next Two Digits (RTO/Regional Transport Office Code)
These numbers identify the district or RTO office within the state where the vehicle was registered.- Example:
- MP04 – Bhopal (Madhya Pradesh)
- MH12 – Pune (Maharashtra)
- Example:
- Next One or Two Letters (Series Code)
This part represents the series of registrations within the RTO. When one series (like ‘AA’) is filled, the next (like ‘AB’) begins. - Last Four Digits (Unique Vehicle Number)
This is the unique number assigned to your vehicle — no two vehicles under the same RTO can have the same one.- Example: 1234 – your vehicle’s unique ID in that RTO.
🔠 2. Types of Vehicle Number Plates in India
Not all number plates are created equal! Their colors and letter styles indicate the type and purpose of the vehicle.
| Color | Text Color | Vehicle Type / Use |
|---|---|---|
| White | Black | Private vehicle |
| Yellow | Black | Commercial vehicle (taxis, trucks, etc.) |
| Black | Yellow | Rental vehicles (tourist taxis, etc.) |
| Blue | White | Foreign Embassy or Diplomatic vehicles |
| Green | White | Electric private vehicle |
| Green | Yellow | Electric commercial vehicle |
| Red (temporary) | White | Vehicle under temporary registration |
| Red with Emblem | Gold | President/Governor’s official vehicle |
🛠️ 3. Special Number Plates and Their Meanings
Some vehicles have special identifiers on their plates:
- “BH” Series – Introduced in 2021, it stands for Bharat Series, allowing vehicle owners to move across states without re-registering.
- CD Plates – Used by Diplomatic Corps or foreign officials.
- Upgraded VIP Numbers – Certain numbers like 0001, 0007, or 9999 are considered VIP or fancy numbers, often bought through auctions.
🔢 4. Temporary Registration Numbers
When you buy a new vehicle, it often carries a temporary registration (usually red background with white letters) until permanent registration is completed. These are valid for up to 30 days and are used for transportation from showroom to RTO.
⚡ 5. High-Security Registration Plates (HSRP)
Since 2019, all vehicles in India are required to have HSRP (High-Security Registration Plates).
These come with:
- A unique laser-engraved code
- A non-removable snap lock
- A hot-stamped IND mark
This helps prevent vehicle theft, cloning, and fraud — ensuring standardized vehicle identification across India.
🌍 6. Interesting Facts About Number Plates
- Military vehicles use an arrow symbol between the numbers.
- Vintage cars can retain their original numbers, but must register under a separate category.
- VIP numbers can fetch lakhs in auctions — for instance, the number “0001” is among the most sought-after!
