ACNH Custom Design Codes: How to Use, Enter & Customize (2026)

Custom design codes are one of the most powerful creative tools in Animal Crossing: New Horizons. With a single code you can pull down a pattern made by any player in the world and apply it to clothing, paths, furniture, signs, and walls — turning your island into something completely your own. First, though, you need to understand how the system works.

This guide covers everything in order: what the codes are, how to unlock the kiosk, both ways to enter a code, how to apply designs to clothes, paths, and furniture, how to make your own, where to find the best codes, and how to manage your 50-slot inventory without losing any work.

What Are Custom Design Codes? (MO, MA & QR Explained)

Custom designs are 32×32 pixel patterns that apply to dozens of surfaces around your island. Every design shared online comes with at least one of three code types:

• Design ID (MO- code) — a 17-character code for a single specific design. Format: MO-XXXX-XXXX-XXXX. Enter it at the Able Sisters kiosk to download that design.
• Creator ID (MA- code) — a 14-character code tied to a creator's full published catalog. Format: MA-XXXX-XXXX-XXXX. Enter it at the kiosk to browse every design that creator has shared.
• QR Code — a scannable image that transfers the design data through the NookLink smartphone app without typing. Most legacy QR codes from Animal Crossing: New Leaf also still work.

If a site shows both a QR code and an MO- code for the same design, either one works — they produce identical results. The QR method is faster when you're already on your phone; the MO- method works when you only have the code written down.

How to Unlock Custom Designs First

The design kiosk inside Able Sisters — the piece you need to download other players' codes — is locked behind two progression milestones. You cannot use Design IDs or Creator IDs on day one of a new island.

How to Enter Custom Design Codes (Two Methods)

Once Able Sisters is open, you have two ways to add community designs. Use whichever fits your setup.

Method 1 — Using a Design ID or Creator ID (In-Game Kiosk)

The primary method, requiring only your Nintendo Switch.

The design kiosk is on the right wall inside Able Sisters — open 9am–9pm daily.

Type the MO- code including every dash — one typo is enough to break the search.

Method 2 — Scanning a QR Code (NookLink App)

When a site provides a QR code image, scan it with your phone and skip typing entirely.

Open NookLink → Designs → Scan a QR code, then point your camera at the image.

How to Use & Apply Your Custom Designs

Once a design is saved, you can apply it to clothing, ground tiles, and furniture.

Clothing & Accessories

Open your Custom Designs app → select a design → Wear it to try it on instantly. By default the design appears as a simple canvas tee. For a proper clothing item with a cut and collar, take the design to the fitting room panels inside Able Sisters and purchase it as an actual wearable piece.

For full garment shapes — hoodies, dresses, long-sleeve shirts — unlock Pro Designs for 800 Nook Miles at the Nook Stop terminal. The Pro editor shows front, back, and sleeve panels separately so patterns wrap correctly around a 3D character. Community creators share thousands of clothing codes on Reddit r/ACQR and Nook's Island — search by style to find ready-to-wear designs.

Paths & Ground

Path codes replace the ground texture on outdoor tiles — the most popular use of custom designs. You can find curated stone, cobblestone, dirt, and brick sets with matching corner and edge tiles on Nook's Island (nooksisland.com) and Reddit r/ACQR.

Stand on the tile you want to pave → open Custom Designs → select the path → Place here.

Furniture, Signs & Walls

Simple Panels, Customizable Bulletin Boards, and many furniture items accept custom designs directly. Stand near the item → press A → Customize → Design Patterns → choose a design from your app.

For indoor walls, interact with the wall → Change Wallpaper → select a pattern from your Custom Designs app. This is the fastest way to display art or create themed room dividers without using a furniture slot.

Simple Panels are the easiest way to display a custom design as in-game artwork.

How to Customize and Create Your Own Designs

The Custom Designs app includes a built-in 32×32 pixel editor with a 15-color palette — no third-party tools required.

1. Open your Nook Phone → Custom Designs → tap an empty slot → Create a design.
2. Use the brush, bucket fill, and eraser tools to paint your pattern on the grid.
3. Select Share it when finished. The game generates your own MO- and MA- codes automatically.

The Pro Designs editor shows all garment panels — front, back, and both sleeves.

Unlock the custom design pro editor for 800 Nook Miles to access full garment templates with front, back, and sleeve panels. Essential for clothing that wraps properly around a character rather than just tiling flat.

Where to Find the Best Custom Design Codes

The best community sources for free custom design codes:

• Nook's Island (nooksisland.com) — large searchable database with pattern previews and MO- codes
• Reddit r/ACQR and r/AnimalCrossing — active creator communities posting original designs daily with codes in comments
• Pinterest and TikTok — great for visual discovery; creators usually include MO- codes in captions or video overlays
• Dream Islands — visit via a DA- dream code, spot designs you like, then note the creator's MA- code from the QR board in their home

Filter by category on Nook's Island to find exactly what you need — paths, clothing, flags, banners, and seasonal sets are all well represented with MO- codes ready to copy.

Managing Your Design Slots

Your Custom Designs app has exactly 50 slots shared between regular and Pro Designs. There is no way to increase this. Running out of slots is the most common reason new codes refuse to download.

• Remove designs from surfaces before deleting slots. Stand on a placed path tile and press Y to pick it up first. Deleting a slot while it's actively applied to your island leaves an unremovable pattern behind.
• Screenshot MO- codes before clearing slots. Open the design, capture the code on screen, and you can always re-download it later without any work lost.
• Group designs by use case. Keep all tiles from the same path set in consecutive slots so matching variants are easy to find while you're decorating.
