Jigsaw Puzzle Manufacturers

Each puzzle is unique. Because the dies used to cut puzzles shift slightly from puzzle to puzzle and batch to batch, individual missing pieces from a puzzle can not be replaced. However, if you believe a piece was missing from the sealed box when you opened it, most manufacturers will send you a replacement puzzle direct from the factory at no cost. They may ask that you send them proof of purchase (like the barcode from the box) and/or a piece from the puzzle. 

Here is manufacturer contact info to request replacement of a defective or incomplete jigsaw puzzle or product.
