Vehicle registration plates in India are more than just a combination of letters and numbers. The background colour and the colour of the registration characters can indicate the category and intended use of the vehicle, ranging from privately owned cars and commercial taxis to electric vehicles, rental cars and diplomatic vehicles.
A graphic explaining India's different number plate colours has recently been circulating online. While much of the information is directionally correct, there are some important distinctions that vehicle owners should know.
Here is an explainer based on the colour classifications notified under India's motor vehicle regulations.
White Number Plate With Black Letters – Private Vehicles
The most commonly seen registration plate in India is a white background with black lettering.
It is used for non-transport vehicles, which typically include privately owned cars and two-wheelers that are not being used commercially.
For example:
KA 01 AB 1234
A privately owned hatchback, SUV, sedan or motorcycle will ordinarily fall under this category.
The Government's notified vehicle-class table identifies:
Non-Transport Vehicle: Black lettering on White background.
This remains the standard number plate format for conventional privately registered vehicles.
Yellow Number Plate With Black Letters – Commercial / Transport Vehicles
A yellow background with black lettering identifies a vehicle registered as a transport vehicle.
These plates are commonly seen on:
Taxis
Commercial passenger vehicles
Goods carriers
Trucks
Buses
Other transport-category vehicles
The official classification specifies black alphanumeric characters on a yellow background for transport vehicles.
So, when you see a yellow plate on a car, it generally indicates that the vehicle has been registered for commercial or transport use rather than ordinary private ownership.
Black Number Plate With Yellow Letters – Rent-a-Cab Vehicles
A less common format consists of a black background with yellow lettering.
Under the notified classification, this combination is applicable to transport vehicles operating under the Rent-a-Cab scheme.
These vehicles should not simply be confused with every self-drive rental vehicle or commercial vehicle. The classification is specifically linked to vehicles registered under the applicable rental transport category.
The key distinction is:
Yellow letters + Black background = Rent-a-Cab transport vehicle.
Green Number Plates – Electric Vehicles
India introduced dedicated green registration plates for battery-operated vehicles as part of efforts to clearly identify electric vehicles.
However, the colour of the letters changes depending on whether the EV is privately or commercially registered.
Private Electric Vehicle
A non-transport battery-operated vehicle uses:
White letters on a Green background
Commercial Electric Vehicle
A transport-category battery-operated vehicle uses:
Yellow letters on a Green background
The notified rules separately classify battery-operated non-transport and transport vehicles using these two combinations.
This means that simply saying "green number plate means EV" is only part of the story—the lettering colour can also tell you whether the EV is privately or commercially registered.
What About Electric Rental Cars?
Battery-operated vehicles registered under the Rent-a-Cab category have another combination:
Black letters on a Green background.
Therefore, India's EV registration system can effectively use different text colours depending on the registration category of the electric vehicle.
Temporary Registration Plate – Red Letters on Yellow Background
This is one area where several social-media explainers get it wrong.
A temporarily registered motor vehicle is officially specified as having:
Red alphanumeric characters on a Yellow background.
Temporary registration is generally issued before permanent registration is completed and is valid according to the applicable registration rules.
Therefore, a red background with white lettering should not be described as the standard temporary-registration plate.
Red Number Plate With White Letters – Vehicles With Dealers
A red background with white lettering is instead associated with vehicles in the possession of dealers under the notified registration-colour classification.
This distinction is important because viral number-plate charts often incorrectly label such plates as temporary registrations.
In simple terms:
Temporary registration: Red text / Yellow backgroundDealer vehicle: White text / Red background
Blue Number Plates – Diplomatic and Consular Vehicles
Diplomatic vehicles use special registration formats that differ from ordinary state-registration plates.
Official rules provide for different diplomatic and consular classifications, including vehicles associated with diplomatic missions, consular posts and certain international organisations.
The notified colour table includes:
White characters on Deep Blue for diplomatic / consular / diplomatic-mission categories
Yellow characters on Deep Blue for certain consular registrations carrying identifiers such as CC, UN or IOC
White characters on Light Green for specified home-based non-diplomatic officials of diplomatic missions or consular posts.
Therefore, the commonly used term "blue diplomatic plate" is broadly understandable, but diplomatic registration colours are actually more detailed than a single blue-plate category.
What Do CD, CC and UN Mean?
Special diplomatic registrations can use identifying letters associated with the status of the vehicle.
Depending on the category, markings can include abbreviations such as:
CD – Diplomatic-related registrationCC – Consular Corps / consular registrationUN –
Vehicles connected with specified United Nations organisations
The Central Motor Vehicles Rules contain separate provisions governing registration marks and display requirements for diplomatic and consular vehicles.
What About Vehicles Displaying the National Emblem?
Another category often shown in online graphics is a red plate carrying the State Emblem of India.
However, this should not be treated as another ordinary number-plate category equivalent to white, yellow or green registration plates.
Vehicles used for specified constitutional or official purposes can operate under special protocols and regulations, and certain official vehicles have historically been classified separately from conventional civilian registrations.
The government's rules and notifications also recognise special treatment for official vehicles belonging to constitutional authorities and designated dignitaries.
Therefore, referring to a generic "National Emblem Plate" for all government vehicles would be misleading. Most government-owned vehicles still carry normal registration numbers according to their applicable category.
Where Does the BH-Series Fit In?
The Bharat Series, or BH-Series, is not identified by a unique plate colour.
BH-Series vehicles continue to use:
The difference is in the registration format.
A BH registration follows the pattern:
YY BH #### XX
where:
YY represents the year of first registration
BH identifies the Bharat Series
#### is a four-digit number
XX represents the alphabetic series
MoRTH introduced the BH-Series to make interstate relocation easier for eligible vehicle owners by removing the need to obtain a fresh state registration every time they move permanently from one state to another.

Why Does India Use Different Number Plate Colours?
Number plate colours allow enforcement agencies and road users to quickly recognise the registration category of a vehicle.
They can help distinguish whether the vehicle is:
Privately registered
Used commercially
Part of a rental fleet
Battery electric
Temporarily registered
Held by a dealer
Registered under diplomatic provisions
The registration mark itself still remains the primary identifier linked to the vehicle's official registration records.
Auto Punditz Take
India's colour-coded registration system looks simple at first glance, but it contains significantly more detail than the familiar white-private and yellow-commercial distinction.
The growth of electric mobility has added another layer, with green plates now differentiated by white, yellow or black lettering depending on the EV's registration category.
More importantly, motorists should be cautious about viral number-plate charts. One frequently repeated mistake is describing white text on a red plate as temporary registration. Official rules specify red text on yellow for temporary registration, while white on red identifies vehicles in the possession of dealers.
Understanding these differences can make it surprisingly easy to identify the broad registration category of almost any vehicle you encounter on Indian roads.
