Question 1

What is a LEGO piece identifier?

Accepted Answer

A LEGO piece identifier helps you identify an unknown LEGO part from a photo or catalog search. BrickFinder returns likely Design IDs, colors, and related set information from a local Rebrickable-derived catalog.

Question 2

How accurate is the BrickFinder photo identifier?

Accepted Answer

Accuracy depends on lighting, focus, and how unique the piece is. Clear, well-lit photos of a single piece against a plain background work best. Results are confidence-ranked matches — always confirm against the physical mold and catalog entry.

Question 3

Are my photos stored or processed on-device?

Accepted Answer

Photos are sent to BrickFinder’s server for ephemeral vision analysis (Google Gemini and/or OpenRouter). They are not kept as a photo library and are not used to train BrickFinder’s product models. See the Privacy Policy for details.

Question 4

What is the difference between a Part Number (Design ID) and an Element ID?

Accepted Answer

A Design ID (e.g. 3001) is the mold / shape regardless of color. An Element ID (e.g. 300121) is a specific Design ID produced in a specific color, often printed in instructions.

Question 5

Can I identify LEGO Technic pieces and minifigure parts?

Accepted Answer

Yes. The catalog and tools cover classic bricks, plates, tiles, slopes, Technic elements, round pieces, and many minifigure torsos, heads, and accessories. Use the Minifigure Decoder for printed torsos and faces.

Question 6

Can BrickFinder identify non-LEGO or clone brand bricks?

Accepted Answer

BrickFinder is tuned for official LEGO geometry and catalog IDs. Clone bricks may look similar by stud count, but Design IDs and set membership are only authoritative for genuine LEGO elements.

Question 7

How do I find which LEGO sets contain a specific piece?

Accepted Answer

Open the part detail page after identify or Part Lookup. The “Found in Sets” section lists set numbers when inventory data is available — click a set card to open set details.

Question 8

Can I order replacement LEGO pieces from BrickFinder?

Accepted Answer

No. BrickFinder is a discovery and catalog tool. Use Replacement Finder to build a missing-parts list, then order via LEGO Pick a Brick, BrickLink, or other marketplaces.

Question 9

How should I photograph a LEGO piece for identification?

Accepted Answer

Use good lighting, a simple background, keep the piece in focus, and show studs or underside tubes clearly. One piece per photo is easier than a crowded pile (use Pile Scanner for trays).

Question 10

Is BrickFinder free?

Accepted Answer

Yes. Core identification and catalog tools are free to use. Free AI providers may rate-limit under heavy load; Gemini is used as a backup when configured.
