How do you find a missing LEGO part?

Lost a brick, repairing a build or completing a second-hand set? Searching by set number helps you find the part references and colours in your model without knowing every part’s name.

Find the set number
Look on the box or the cover of the instructions. Enter, for example, 76917 or 76917-1 in the field above. When an image is available, it appears with the result to help you check the model.
Check the part and colour
Compare the part’s shape with your instructions. Results match the references and colours in the set’s recorded parts list. Filter by name or reference to find the part you need more quickly.
Choose the condition and quantity
Choose new or used according to the available offers. The “In this set” quantity is a guide and may differ from the number you are missing. Adding to your basket defaults to one part; adjust the quantity before ordering.

Can’t find your set or part?

Not every set’s parts list has been recorded yet. Results show matching offers with a photo, so a part missing from the results may still belong to your model.

If you know the reference, use the parts catalogue. Parts catalogue.
