Every VELUX product has its own unique product code, so it's completely normal for the code on your new blind to look slightly different from the code on your roof window. Below, we'll break down what each part means, so you can order with confidence.
Roof Window Codes Explained
A VELUX roof window code is made up of three parts; however, in most situations, the type and size are what we need from you when ordering a blind:
- The window type — letter combinations such as GGL, GPL, or GGU. These tell you the style of the roof window (e.g. centre pivot, top-hung).
-
The window size — numbers or letter-number combinations such as 1, 2, C04, or MK04. These tell you the size of the window.
Both the type and size are essential when ordering a blind, as the configurator uses them to match the blind perfectly to your window.

Blind Codes Explained
Blind codes are a little more detailed and are made up of four parts. Let's break down an example:
Example: DKL MK04 0705 S
| Part | Example | What it means |
| 1. Blind style | DKL | The type of blind you've selected (DKL = Original VELUX Blackout Roller Blind). Each blind style has its own identifier. |
| 2. Blind size | MK04 | The size of the blind. This must match your roof window size code exactly. Please note the size code can vary slightly depending on the age of your window so in some occasions, this may look different once the blind is configured. |
| 3. Fabric colour | 0705 | The colour of the blind fabric (0705 = grey, for example). |
| 4. Frame colour | S | The frame colour (S = silver). You may also see WL at the end, which means White Line — this appears when your chosen blind offers a frame colour option. |
Why do I sometimes see another character after the frame colour code?
Don't worry, if you spot a code ending in something like SC, SG, WL, or WLG (for example DKL MK04 0705SG), this is the same blind as one ending in just S or WL. The only difference is the warehouse the blind is dispatched from.
So, the following are all the same blind, just shipped from different locations:
- DKL MK04 0705 S
- DKL MK04 0705 SG
- DKL MK04 0705 SC
You may also see additional letter variations at the end of the code — these follow the same logic and simply indicate the dispatch location, not a different blind.
✅ The Key Takeaway
You may receive a blind code starting with DKL, FHC, DBL, or PAR — but these simply refer to the style of blind you selected as part of the ordering process. If you've entered your window type and window size correctly during ordering, your blind will be a perfect fit for your window. If you haven't placed your order yet, you can start configuring your new blind here.
