LEGO Missing Piece Checker

Enter a set number, mark each piece found or missing, and leave with a list of what is missing, the element IDs LEGO asks for and links to buy the parts. It is free and needs no account. Rule out the usual hiding places first.

130 pieces in 50 part and color combinations, plus 1 minifigure.

LEGO counts 135 pieces. This inventory comes from a separate parts catalog and lists 136, including the 6 parts inside the minifigures; the two do not always count the same elements, so their totals differ. Spare parts are counted in neither figure.

Before you call it missing

Builders who report a missing piece often find it in one of these places. Tick each one off as you look.

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.
