Ever opened a bin of mixed LEGO parts and tried to rebuild a set? It’s painful. Which bag had the tiny dark bluish gray plates? Where did those technic pins go? That’s exactly the problem Brick Bag Inventory solves.
What Is Brick Bag Inventory?
Brick Bag Inventory is a free tool that gives you detailed, part-by-part inventories organized by numbered bag. Search for any LEGO set, and you’ll see exactly which pieces belong in each bag — complete with images, quantities, and colors.
Every inventory is hand-verified by following the official LEGO instructions step by step. No guesswork, no automation errors.

Why I Built This
As LEGO collectors, we all end up with bins of loose parts from disassembled sets. Rebuilding should be fun, not frustrating. The official LEGO instructions tell you what to build, but they don’t tell you what should be in each bag. Brick Bag Inventory fills that gap.
Try It Out
Head over to brickbaginventory.com and search for your set. It’s completely free — no account needed. And if your set isn’t listed yet, submit a request and I’ll get it added.
Happy rebuilding!
