LEGO Replacement Parts: 3-Step Official Request Guide
Short answer first: the LEGO replacement parts process is not complicated. Everything happens on the official customer service pages, standard parts are replaced free of charge, and in most regions shipping is free too. Filling in one request takes roughly 10 minutes, and delivery usually takes 7-21 days after you submit. If the part is out of stock on the official site, then fall back on BrickLink or brickplan's loose-parts listings.
Step 1: Sign In to the LEGO Website and Find the Missing Parts Entry
Open the LEGO website, sign in or register an account, go to the Customer Service section and look for the "Missing Parts" entry. The site supports searching by set: type the five-digit set number printed on the box (10305, for example) and it will pull up the matching set.
Step 2: Select the Missing Parts and Check the Details
Once you are on the set page, tick the missing parts in the parts list. You can request up to 10 different parts per submission. The system shows the part number, colour and an illustration for each line, so check every one carefully. If you do not know a part number, look it up by set in brickplan's parts library first — choosing the wrong colour means filing a second request later.
Step 3: Enter Your Address and Submit the Request
Fill in an accurate shipping address in English, plus your email and contact details, then submit. LEGO sends a confirmation email containing your request number; screenshot it and keep it on file. Shipping normally takes 7-21 days. Parts from popular sets still in production can arrive faster, while parts from retired or discontinued sets may be refused outright.
Processing Times and the Free Replacement Policy
Official LEGO replacements are free of charge, though a small shipping fee applies in some countries and regions. If the set is still on sale and the part has not been discontinued, your request has a high success rate. If the part is out of stock on the site, you can contact customer service and ask them to note down a "wanted list" so it is queued for restocking — the wait is usually one to two months.
What to Do If Your Request Is Refused
If LEGO turns you down or the wait is too long, builders in China can turn to brickplan's loose-parts market or to domestic part channels such as Gobricks and Double Eagle. Same-number domestic parts cost roughly 0.1-0.5 RMB per piece and arrive within 7 days, with appearance and clutch close to the original. That makes them fine as a stopgap — swap the original parts back in once they turn up.
FAQ
Q: Does the LEGO replacement parts process cost anything? A: Official LEGO replacements are free, and in most regions shipping is free as well, so you only fill in the request details and your address. Only a few regions or expedited channels charge a small shipping fee, and the page states the cost clearly before you submit.
Q: How long do LEGO replacement parts take to arrive? A: From submission to dispatch usually takes 7-21 days, and popular sets still on sale move faster. If the website shows the part as out of stock the wait can stretch longer; if nothing has shipped after a month, contact customer service to chase it up.
Q: How many parts can I request at one time? A: The website accepts up to 10 different parts per request, with no limit on the quantity of each part. If you are missing more than 10 types, submit in several batches — but do not request the same part twice within one order.
Q: How do I get a part that is not on the LEGO website? A: Retired or discontinued parts often show as out of stock on the official site. Look for used original parts on BrickLink, or substitute a same-number domestic part through brickplan, which is cheaper and quicker to arrive.
