Turn a QR code into a BrickLink wanted list

The download is a wanted list XML in BrickLink's own format. Every line is a real catalog item: the part number for the element you chose, the BrickLink color ID, and the quantity the packer worked out. A 32×32 baseplate in your chosen baseplate color is added as a single extra line, so the list covers the whole build rather than just the code.

Because the quantities come from the same packer that draws the preview, the list and the build always agree. Change the color or the element and the list changes with it.

On BrickLink, go to My BrickLink → Wanted → Upload, pick the XML file, and confirm. BrickLink creates a wanted list with every part and quantity filled in, which you can then match against sellers and buy — usually from one or two stores rather than hunting part by part.

A parts list is useless if half of it does not exist. brickcodes picks from 18 piece colors and 11 baseplate colors that are verified against the BrickLink catalog, and the fitter is only ever given the sizes that exist in the color and element you picked. If a color is missing a particular size, the packer simply never uses it — so you cannot generate a list that no seller can fill.

The same code can be built four ways, and each maps to a different set of BrickLink part numbers: flat tiles for a smooth finish, studded plates, taller bricks, or round 1×1 plates for a dotted look. Tiles, plates and bricks are packed from sizes between 1×1 and 2×6, so the piece count stays low; round plates are 1×1 only, which looks striking but costs the most pieces.

Curious what that does to the total before you buy? See how the piece count is calculated.

Alongside the wanted list, you can export a printable PDF build sheet with the plate layout and the full bill of materials, or copy the parts list to your clipboard as plain text. Everything is generated in your browser — no account, and nothing is uploaded to a server.
