📋Quick Answer: What is a SKU on Etsy?

SKU stands for Stock Keeping Unit. It's an alphanumeric code (letters and numbers) that you create to uniquely identify each product and variation in your Etsy shop.

Example SKU breakdown:

NKL-GLD-CHKR-18

NKL = Product type (Necklace)
GLD = Material (Gold)
CHKR = Style (Choker)
18 = Size (18 inches)

Key points: SKUs are optional but highly recommended. They're private (buyers can't see them). Maximum 32 characters per SKU.

Pro tip: Start using SKUs when you have 20+ products or multiple variations per listing.

How to Set Up SKUs on Etsy

5-step process to implement your SKU system

Define Your Categories

List all product types in your shop and create 2-3 letter abbreviations for each.

Example: Necklace = NKL, T-Shirt = TSH, Planner = PLN, Candle = CND

Identify Key Attributes

Determine which attributes matter: color, size, material, style, or theme.

Example: Colors: BLK, WHT, RED | Sizes: SM, MD, LG, XL | Materials: GLD, SLV, CTN

Create Your Format

Establish a consistent format with hyphens between segments.

Example: [Category]-[Style]-[Color]-[Size] becomes TSH-VNK-BLK-LG

Document Your System

Create a reference spreadsheet listing all abbreviations and meanings.

Example: Keep a Google Sheet with all codes so anyone can decode or create SKUs

Apply to Listings

Add SKUs in the variations or inventory section of each Etsy listing.

Example: Edit listing > Variations > Enter SKU for each color/size combination

SKU Do's and Don'ts

+ Do This

-Keep it short: Aim for under 15 characters
-Use consistent format: Same structure for all products
-Document everything: Create a reference guide
-Use hyphens: Improves readability (NKL-GLD-18)
-Make it descriptive: SKU should hint at the product
-Use uppercase: Easier to read quickly

- Avoid This

-Don't use only numbers: 001, 002 is meaningless
-Don't mix O and 0: Causes confusion (use zero)
-Don't use spaces: Breaks CSV exports
-Don't change formats: Stay consistent shop-wide
-Don't reuse old SKUs: Retired = retired forever
-Don't exceed 32 chars: Etsy's hard limit

Frequently Asked Questions

Everything you need to know about SKUs on Etsy

SKU stands for Stock Keeping Unit. On Etsy, it's an optional alphanumeric code you assign to each product variation to track inventory, identify items quickly, and organize your shop. SKUs are internal codes visible only to you (the seller), not to buyers. Etsy allows up to 32 characters per SKU.

No, SKUs are completely optional on Etsy. However, they become essential as your shop grows beyond 20-30 products or when you have multiple variations per listing. Sellers who use SKUs report 40% faster order fulfillment and fewer shipping errors.

When creating or editing a listing, scroll to the 'Variations' section. For each variation (size, color, etc.), you'll see a SKU field. Enter your unique code (up to 32 characters). For listings without variations, add the SKU in the 'Inventory and pricing' section. Click 'Save' to apply.

A good SKU format is: consistent, descriptive, and scalable. Use a structure like: [Category]-[Product]-[Variation]-[Size]. Example: JWL-NKL-GLD-18 (Jewelry-Necklace-Gold-18inch). Avoid spaces, special characters, and confusing letters (O vs 0, I vs 1). Keep it under 15 characters for easy scanning.

No, SKUs are completely private. Buyers never see your SKU codes on your listing, in their cart, or on order confirmations. SKUs appear only in your seller dashboard, order notifications, and CSV exports. This means you can use any internal coding system without worrying about customer confusion.

SKUs let you instantly identify exact products during fulfillment, track which variations sell best, sync inventory across platforms (Etsy, Shopify, Amazon), generate accurate restocking reports, and reduce picking errors. Shops using SKUs report 60% fewer wrong-item shipments.

Yes, you can edit SKUs anytime by going to your listing, clicking 'Edit', and updating the SKU field for any variation. Changes take effect immediately. However, avoid changing SKUs frequently as it can disrupt your inventory tracking history and cause confusion in your records.

Etsy SKUs can include letters (A-Z), numbers (0-9), and hyphens (-). The maximum length is 32 characters. Avoid spaces, underscores, and special characters as they may cause issues with CSV exports and inventory software. Stick to uppercase letters for consistency and readability.

Each variation combination gets its own unique SKU. For a t-shirt with 3 colors and 4 sizes, you'd have 12 SKUs (one for each color-size combo). Example: TSH-BLK-SM, TSH-BLK-MD, TSH-WHT-SM, etc. This lets you track inventory and sales for each specific variation.

Yes, using consistent SKUs across Etsy, your website, Amazon, and other platforms is a best practice. It simplifies inventory syncing, prevents overselling, and makes order fulfillment easier. Many inventory management tools like Craftybase and eRank rely on matching SKUs across platforms.

Digital downloads need SKUs too, especially if you sell variations (different file formats, sizes, or bundles). Use a format like: DIG-[Type]-[Theme]-[Version]. Example: DIG-PLNR-FLRL-01 for a digital floral planner. Even though there's no physical inventory, SKUs help track which digital products sell best.

Common mistakes include: using sequential numbers only (hard to identify), making SKUs too long (over 15 characters), using similar-looking characters (O/0, I/1), changing formats mid-catalog, using product names as SKUs (too long), and not documenting your system. Create a SKU guide document and stick to it.
