How contributions work

Every bag inventory on Brick Bag Inventory is built by following the official LEGO instructions step by step. Our system tracks which parts appear at each step and assigns them to the correct numbered bag.

While much of the heavy lifting is automated, every inventory is verified by real contributors before it goes live. This human review ensures accuracy and catches edge cases that automation might miss.

Everyone can contribute

You don't need to be a LEGO expert or commit hours of your time. Contributing is as simple as looking at a photo and identifying a part.

It only takes a few seconds

When you identify a part, you're helping us assign it to the right bag. Even identifying a single part is already helpful — every contribution adds up and helps someone rebuild their set faster.
