Nothing disrupts the joy of a quick build more than the model you’re about to finish suddenly "freezing" just because a crucial brick is missing. Amid a cluttered workbench of pieces and a sense of disappointment, the question that would make any builder wonder is: LEGO missing bricks, what should you do?
Is the brick really missing from packaging, or is it just hiding somewhere around the corner of the room? See below for precise checks and official support procedures to quickly "rescue" your model!
The truth about "LEGO missing bricks": Is it a manufacturing fault?
The LEGO Group applies very strict automated quality controls in production and packaging, so the rate of miscounts or missing details is extremely rare. That said, in a few rare cases, technical errors from the factory can still occur.
In addition, many sets often include some extra parts, mainly small pieces like round studs, plates or 1x1 tiles. Sometimes accidentally using these pieces in earlier steps is the reason you see
LEGO missing bricks in the following steps. Therefore, before insisting that the box is missing a detail, take a few minutes to re-check using the steps below.

5 quick self-check steps when you suspect a LEGO set is missing details
Before sending a support request, take a moment to quickly scan your assembly area:
-
Check the folds of the parts bag: Small bricks or transparent pieces can easily get stuck in the bottom corner of the paper bag or the opened packaging bag.
-
Check the bottom of the carton box: Large base plates, chassis frames, or unnumbered component bags are often tucked against the bottom edge of the box.
-
Cross-check the previous assembly steps: Review the immediately preceding instruction pages to see if you might have accidentally used a similar piece in color or size.
-
Look around the assembly area: Pieces may have rolled under the table, tangled in the carpet fibers, or wedged in the chair gap.
-
Count the number of bags: Compare the actual bag count with the instruction book; note that some large sets may have multiple bags bearing the same number.
If an entire bag of components is missing from the LEGO set?
If you can’t find a numbered bag or there is a large shortfall of components right after opening the box, this is a serious packing issue rather than just a few bricks missing.
At this point, you should not submit requests for individual bricks through the system. Instead, keep the product box intact, the unopened bags, the instruction book, and the purchase receipt, and contact the place of purchase directly for guidance on a replacement under their return policy.
How to find the correct LEGO part number for the missing piece
To search for the replacement part, identifying the exact part ID is the most important step:
Element ID (Part Identification Code): The code used to identify a specific part by its shape and color. For many newer LEGO sets, you can find this code in the parts list at the end of the instruction book.

Design ID: The design identifier code for the part’s shape or geometry (not color-specific), usually 4–5 digits printed or molded on the inner face or bottom of the brick.

When you need to find a replacement part, the Element ID is always the most useful code. If you no longer have the printed book, you can look up the electronic guide on the LEGO website, the LEGO Builder app, or consult the BrickLink community database to find the missing LEGO piece.
Guide to submitting a replacement brick request on the LEGO website
The LEGO Group manages replacement parts service through a global online support portal. However, the ability to accept orders and ship parts depends on the countries or regions supported by the system at the time of submission.
You can follow the process with the steps below:
Step 1: Access LEGO's official service page in the Missing Pieces section (lego.com/service/replacement-parts).
Step 2: Choose the correct country or region for delivery and check the terms shown on screen.

Step 3: Enter the LEGO Set Number (Set Number – printed on the box or the instruction book cover).

Step 4: Enter the Element ID you looked up (or search by the displayed parts catalog), select the part and the quantity to be added.

Step 5: Fill out the recipient information completely according to the fields on the system’s form.

Note: If the delivery region is not included in the system’s direct shipping list, you should contact LEGO's customer support channel directly to receive guidance on an appropriate replacement solution.
Cách xử lý khi bộ LEGO mua tại Mykingdom bị thiếu gạch
All LEGO products at Mykingdom come as sealed sets from the manufacturer. Mykingdom does not store loose replacement parts and does not provide replacements or exchanges for individual bricks at the store. The process for accepting replacement parts will be carried out by players directly on LEGO's website.
However, if you encounter obstacles during the process (language barriers, unclear how to look up the Element ID, or how to fill out the form), you can contact Mykingdom's Customer Care team via the Fanpage or Hotline 1900 1208 to receive guidance on the steps in the most convenient way.
Giải pháp bổ sung gạch cho các bộ LEGO đã chơi lâu ngày
After long use or display, losing a few bricks is something players find hard to avoid. If you’re only missing standard structural bricks, the LEGO Classic Creative Bricks Box product line will be the quickest and most economical replacement solution.

With hundreds of bricks in a variety of colors and sizes, along with wheel details and frames, you not only can easily fill in the missing spots but also have a rich "brick stash" ready to freely expand the model as you like.
Note: LEGO Classic mainly provides basic building bricks. If your model is missing specialized components (such as a minifigure, race car cockpit windshield, propellers, or Technic gears...), you should consider buying loose parts via the Pick a Brick service on the LEGO website or search within reputable LEGO community groups.
