Start with LEGO’s official Replacement Parts service, then choose the route that matches the problem: a missing individual piece, a broken piece, a missing bag, or a part lost from an older set. Before submitting a request or buying a replacement, identify the set and the exact piece. LEGO’s options and eligibility can vary by country, product line, and current stock.

Choose the right route for the problem

What happened Where to start
An individual piece is missing from a new set Choose LEGO’s missing-pieces route on the local Replacement Parts page.
A piece arrived broken or damaged in a new set Choose the broken-pieces route. LEGO’s US customer-service page says broken-piece replacements can be requested free of charge; check your country’s page for its current terms.
An entire bag is missing Use LEGO’s dedicated Missing bags in new sets support topic rather than listing every piece in the bag individually.
A piece was lost from an older set Check LEGO’s older-set replacement guidance and search by the exact part identifier. Availability is not guaranteed.
You need a booklet or a special component Use the matching support topic; LEGO lists separate help for instructions and special pieces.

These are distinct cases, not one universal replacement form. LEGO’s US support uses the labels “Missing Bricks,” “Broken Bricks,” and “Buy Bricks”; other country pages may use different wording.

Find the set number and piece number

  1. Find the set number. Check the box or building instructions. If you no longer have either, LEGO’s support index includes help for identifying set numbers.
  2. Open the instructions’ parts inventory. Find the element in the contents list and note its piece number, color, and quantity. LEGO’s support topics explain how to identify piece numbers and special pieces.
  3. Check the details before submitting. Make sure the part number and color match the piece shown in the inventory. If you cannot confidently identify it, contact LEGO support rather than guessing.

Having the set number, piece number, country, and a short description of the issue ready helps you choose the appropriate support route.

Request a replacement from LEGO

Open LEGO’s country-specific Replacement Parts page and select the option matching your situation. LEGO’s help index separates missing pieces, damaged pieces in new sets, missing bags, older-set replacements, and parts customers want to buy.

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
  • Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
  • Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
  • Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

Do not assume that a replacement will be free in every country or for every situation. LEGO’s US customer-service page describes free broken-brick replacement requests, while regional pages present their own routes and terms. Check the live page for your location, especially for an ordinary lost piece or a retired set.

Buy the piece if a replacement request is not the right fit

Buying a piece is a separate option from requesting a replacement. LEGO’s US customer-service page points buyers to Pick a Brick; LEGO’s Canada page lists a distinct “Buy pieces” route. Search using the exact piece number and confirm color and availability before ordering.

If LEGO does not offer the exact part, a parts marketplace may be another option. Treat that as a purchase, not an official LEGO replacement: verify the seller, part identity, color, condition, and compatibility before paying. Stock can vary, particularly for older parts.

Check the LEGO Education route for Education sets

For LEGO Education sets, first see whether the relevant replacement pack for commonly lost elements covers the piece. For elements outside those packs, LEGO Education directs users to LEGO.com; its guidance also provides item-number and distributor information, including local distributors for users outside the US.

Contact LEGO support if you cannot identify or order the part

Use the customer-support route on your local LEGO service page if the online form does not fit the case, the part cannot be identified, or you need help confirming availability. Include the set number, piece number if known, your country, and a concise description of whether the piece was missing, damaged, or lost. LEGO lists replacement options, but does not describe this as a repair service; its Canada page says it does not provide repair services or maintenance and repair information.
