Missing or defective LEGO pieces: what to do?

Missing or defective LEGO pieces: what to do?

LEGO is one of the most attentive toy companies to the quality of its products, with several checks during production to ensure the completeness and above all the safety of its sets.

Very often LEGO includes some extra pieces in its sets because it prefers to be wrong for excess than for defect in counting the pieces. However, in rare occasions it can happen that a LEGO set has missing or defective parts.

If you have just opened a new LEGO set and you have noticed that there are missing or defective pieces, don’t despair! There are some simple solutions you can try to solve the problem.

First of all, carefully check the set and make sure you haven’t simply lost some pieces. Sometimes they can end up under the sofa or behind a piece of furniture, very often they are hidden in the plastic bags or in the box of the set, so look around to be sure you haven’t lost them in the surroundings.

Have you checked everywhere and are you sure the pieces are missing or defective? What to do in these cases?
Don’t worry! The excellent LEGO customer service is almost always able to solve these small problems.

Missing or defective LEGO pieces in a set still in production.

If the set in question is still in production, the problem of missing or defective pieces is easily solved.

All you have to do is contact the LEGO Customer Service through this page, select whether the problem concerns missing bricks or broken bricks, and complete the report indicating:

  • Your country of residence
  • The code of the set
  • The missing or defective pieces
  • Your contact and shipping details

Verified the final summary and sent the report, you won’t have to wait long before being contacted by customer service that will confirm that it has sent the requested replacement pieces for free.

The missing or defective pieces replacement service is completely free, but this does not mean that it is possible to abuse it to get free LEGO pieces.

The LEGO customer service may in fact request additional information to verify the legitimacy of the request, such as photos of the broken pieces or the communication of a unique code present in the instructions.

Users discovered “cheating” may risk a ban and account closure, so we invite everyone to use this service honestly and responsibly.

What if the set is out of production?

LEGO has produced hundreds of sets and thousands of different pieces over the years. After the withdrawal of a set, replacement pieces are kept for a few years, but after too much time it is possible that they are exhausted or no longer available.

The advice is always to contact LEGO Customer Service even for old and out-of-production sets: if the missing pieces are common enough, it is in fact possible that they are still available.

On the other hand, if it is impossible for customer service to recover the pieces to be replaced, our advice is to look for them in the huge Bricklink catalog, the marketplace specializing in the resale of LEGO sets and pieces.


In conclusion, LEGO is a company that cares about the quality of its products and the well-being of its customers. If you should find missing or defective pieces in one of your sets, don’t despair. LEGO customer service is available to provide a solution, such as sending you the missing pieces or providing you with a refund or discount for your next purchase. In addition, if the set in question is still in production, you can easily request replacement pieces through the LEGO Assistance website. If the set is old or out of production, there may be limitations on the availability of replacement pieces. In any case, LEGO customer service will do its best to help you resolve the problem of missing or defective pieces.
