Frequently asked questions

Brick Bag Inventory is a free tool that shows you exactly which LEGO parts belong in each numbered bag of a set. Instead of sorting through hundreds of loose pieces, you can look up any bag number and see every part it should contain — with quantities, colors, and part images.

Each bag inventory is built by carefully following the official LEGO building instructions step by step. At every step, we record which pieces are used and which numbered bag they came from. The community also helps speed up the process by identifying parts from photos — the more people pitch in, the faster new inventories become available.

Very accurate. Because inventories are created by following the official instructions step by step, every part is tracked to its exact bag. Community-identified parts go through a review process before being published. Since much of this is done by hand, mistakes can happen — if you spot anything wrong, please contact us so we can fix it.

If no bag inventory is available for your set, you can submit a request from the set page — we prioritize sets with the most requests. You can also help speed things up by identifying parts from photos. The more the community contributes, the faster new inventories become available.

Yes, completely free. Searching sets, viewing bag contents, and exporting parts lists costs nothing.

A BSX file is a BrickLink-compatible XML file. BrickLink sellers can export a bag's parts list as BSX and import it into tools like BrickStore, making it easy to list individual bag contents for sale on the marketplace.
