LEGO Missing Piece Checker
Rule out the usual hiding places first. If the piece really is gone, check the set piece by piece
and leave with the element ID LEGO asks for, or a link to buy the part.
Checking
574 pieces in 185 part and color combinations, plus 2 minifigures.
The official piece count includes the 9 parts inside the set's minifigures, which this inventory lists separately. Spare parts are counted in neither figure.
Your missing list
LEGO's request form asks for the set number (43240) and each piece's element ID, both listed above.

Tick each piece as you find it, or mark it missing.
When a piece really is missing
Ask LEGO
LEGO takes requests for pieces missing from a new set through its customer service site. The form asks for
the set number and each piece's element ID, the number printed beside the piece in the parts list at the back
of the instructions. This checker lists both.
Request a replacement from LEGO
Buy the piece
Mark a piece missing and your list links it to an eBay search for that part, which also covers pieces from
older or second-hand sets.
Keep a record
Copy or download your missing list (the CSV opens in any spreadsheet), or print the whole checklist and tick
pieces off on paper. Your marks stay in this browser, so you can check a big set over several sittings.
