License plate colours as a world map
You cannot read the characters, but you do not need to. Plate shape, colour and banding identify a country from fifty metres away.

The short version
- Street View blurs the characters on a number plate but never the base colour, the proportions, or the coloured strip on the edge — which is where the country information actually lives.
- A blue strip on the left carrying a circle of stars is the EU standard; a coloured band across the top of the plate is the Mercosur standard in South America. Strip position is the discriminator.
- Some countries run white plates front and rear, others white at the front and yellow at the rear, so the same car reads differently depending on which way it faces.
- Multiple plate colours on ordinary-looking vehicles in one street means a class-based system, where colour encodes private, commercial, electric or government use.
- Long, narrow plates are the European and broad-Asian norm; shorter, taller plates are the North American norm.
Street View blurs faces and plates. It does not blur the colour of the plate, its proportions, or the coloured strip on its edge.
That is all you need. The characters were never the useful part — they are small, they are usually too far away, and by the time you are close enough to read them you have already identified the country from something else.
What survives the blur is the part that was set by national law: how wide the plate is, what colour it is, and what is printed down its edge.
Start with the banding
The single most useful feature on a modern plate is the vertical coloured strip, because it encodes membership of a standards bloc rather than a single country.
- Blue strip on the left, circle of stars
- The EU standard, carried over into several non-EU European states. It does not tell you which European country — but combined with anything else in frame, it is decisive about the region.
- Blue strip elsewhere on the plate
- Right-hand side, or a horizontal band across the top, is used by several countries outside the EU system. The position of the strip is the discriminator, not the colour.
- Coloured band across the top
- Characteristic of the Mercosur system in South America. This one gives you a continent instantly.
Check the strip before you check anything else on the plate. It is the largest block of solid colour on the object, which means it is the last feature to dissolve as distance and blur increase.
Then the base colour
Beyond bands, the base colour itself is often a national choice, and sometimes a functional one.
- White front and rear. The most common single-colour arrangement, and therefore the weakest read on its own.
- White at the front, yellow at the rear. The same car looks different depending on which way it faces — check the orientation before you conclude anything.
- Yellow at both ends. A genuinely narrowing observation when you can see both ends of the same vehicle.
- Black plates with white text. Typically older vehicles under a superseded standard, so this dates the capture as much as it locates it.
Several countries also colour-code by vehicle class: private vehicles one colour, commercial another, electric vehicles a third, government or diplomatic vehicles a fourth.
Shape and proportion
Look at the aspect ratio. It reads at a distance where colour has already washed out, and it splits the world along a line that no other plate feature does.
| Proportion | Where it is standard | What else to check |
|---|---|---|
| Long and narrow | Europe and much of Asia | Edge strip on the left or top |
| Shorter and taller, more rectangular | North America | Regional graphic or state name across the plate |
| Two-line, near-square | Front plates, motorcycles and larger vehicles in several countries | Whether the same vehicle carries a single-line plate at the other end |
Mounting matters too: recessed into a bumper cavity, bolted flat against the bodywork, or hung below the bumper. Mounting style is fixed by the bodywork of the vehicles sold in that market, so it changes far more slowly than the plate design itself.
Regional sub-codes
In several large federal countries, the plate encodes the state, province or region — as a letter prefix, a number, or a small graphic set apart from the main characters.
You cannot always read that code through the blur. You can very often see whether such a code exists and where it sits on the plate, which is a structural observation rather than a textual one.
That is the difference between guessing the country and guessing the state.
Do not over-commit
Plates are frequently too blurred, too distant, or too angled to read reliably. A plate seen edge-on gives you no proportions and a compressed strip. A plate in shadow gives you no colour at all.
Used correctly, the plate is a confirmation instrument. You arrive at a shortlist through driving side, biome and infrastructure, then find one clean plate in frame and close the round on it.
Common questions
Can you identify a country from a license plate in Street View if the plate is blurred?
Usually, yes. Google blurs the characters, not the plate itself, so the base colour, the aspect ratio and any coloured edge strip survive the blur intact. Those three features carry most of the country information, and all of them are readable from a distance at which the text would be useless anyway.
What does the blue strip on the left of a license plate mean?
A blue vertical strip on the left carrying a circle of stars is the EU standard plate, also adopted by several non-EU European states. It does not tell you which European country you are in, but combined with anything else in frame — driving side, script, road line colour — it is decisive about the region.
Why do some cars have a white plate at the front and a yellow one at the rear?
Several countries specify different colours for front and rear plates so that other drivers can tell at a glance whether they are looking at the front or back of a vehicle. In Street View this means the same car reads as two different plate colours depending on which way it faces, so check the orientation before you commit to a colour.
How reliable is a license plate as a clue in a geography game?
Strong when the plate is clear, close and square-on; noise when it is not. Plates are frequently too blurred, too distant or too angled to read reliably, and a half-glimpsed colour is not worth overriding the landscape, the script or the driving side for. Treat a clean plate read as confirmation rather than as the foundation of the guess.
