2D, 3D or 4D Number Plates: What’s the Difference and are they legal?
Choosing the right number plate isn’t just about the registration — the digit style can completely change the look of your car. At Redline Plates, we offer 2D, 3D and 4D options to suit different styles and budgets.
2D plates use printed characters directly onto the reflective plate surface. They have a smooth, flat finish with no raised digits.
They’re a great choice if you want a clean, traditional appearance while keeping the cost down. Our 2D plates are available in a range of legal styles and can be customised to suit your vehicle.

3D plates feature raised characters with a domed, gel-like finish. The digits have depth and catch the light differently from standard printed plates, giving them a more premium appearance.
The best bit? They’re 100% road legal when purchased through Redline Plates.
They’re ideal if you want something that looks smart, modern and premium without being overly aggressive.
4D plates use solid, laser-cut acrylic characters that are raised from the plate surface. Unlike 3D gel characters, the digits have a sharper, more defined appearance with squared-off edges, creating a distinctive, premium finish.
And just like our 3D plates, 4D plates are fully road legal when purchased through Redline Plates.
They’re a popular choice if you’re looking for a bold, modern and premium look that really stands out.
