What is SKU in Shopify

shopify sku generator

SKU, which stands for Stock Keeping Unit, is a unique code comprising numbers and letters assigned to products and their variants by online merchants. These identifiers are essential for efficiently tracking inventory in an e-commerce store powered by Shopify.

Shop owners typically incorporate the following elements into their SKU codes:

  • Manufacturer
  • Brand
  • Styles
  • Sizes
  • Color
  • Product details
  • Pricing
  • Product code
  • Product variant code
  • Categories

This strategy acts as a proactive safeguard against:

  • Stock shortages for popular items
  • Order confusion
  • Incorrect product shipments
  • Inventory mismanagement

Furthermore, implementing your custom product SKU system using a Shopify SKU generator is crucial. It ensures precise tracking and accountability for every product unit available in your store.

Where do businesses use a SKU?

  • Retail stores
  • Online stores
  • Warehouses
  • Printed catalogs
  • Online catalogs
  • Fulfillment centers

Any other facilities requiring inventory management and tracking.

Creating Unique SKU Codes for Shopify

Here’s your step-by-step guide to crafting distinct SKUs for every product and product variant in your Shopify store.

Create a Code With a Fixed Format

Start by creating an SKU format with a fixed order. It’s essential for clarity and consistency. Begin your stock-keeping unit codes with letters instead of numbers. This change simplifies tracking.

To differentiate letters from numbers within your code, use a dash. After that, follow your letter combination with a numerical sequence.

For example, you can use 

    • SKU-1111
    • SKU-1112
    • SKU-1113
    • SKU-1114
    • SKU-1115

It’s also wise to avoid using the number 0 in your SKU to prevent potential confusion with the letter O.”

Calculate the Required Number of Codes


The size of your product catalog directly impacts the quantity of SKU numbers needed. Therefore, retail and online stores with vast inventories will likely require more extensive codes.

Nevertheless, a general guideline is to maintain concise Shopify SKU codes to enhance readability and comprehension.

Excessively long or intricate SKU codes could lead to difficulties in human readability and hinder efficient inventory management.

Key Guidelines for SKUs

Keep in mind that each of your product SKUs should maintain its uniqueness. While Shopify doesn’t explicitly prohibit duplicate SKUs, it’s advisable to ensure that every SKU remains distinct. This practice enables seamless automatic updates of pricing and inventory upon customer orders.

  • SKU codes usually follow a common structure with 3-4 sections, each spanning under 15 characters.
  • An example SKU for an online clothing store might represent brand, size, style, and color.
  • A format like 984-3230-501-1 could signify brand (984), size (32 x 30), style (501, slim cut), and color (1, black).
  • Different businesses may require unique SKU formats tailored to their specific needs.

How SKU Codes Look on Printed Labels


Adding an SKU code to printed labels is a valuable practice for online stores and e-commerce businesses. Although not obligatory, it offers customers an additional means of order tracking. When printing labels for Shopify orders, the distinct code or SKU number is prominently displayed above the barcode.

Optimal Guidelines for Shopify SKU Codes

Enhance your SKU tracking and simplify stock-keeping unit identification using the following strategies:

  • Label products and their descriptions using your code. The initial letter may represent the product type, followed by the color. For instance, when creating an SKU code for blue men’s sneakers, use a unique code like MSB-115.
  • Categorize SKUs based on similarities. When selling T-shirts, it’s more effective to differentiate them by color. For plain women’s shirts in blue, pink, white, and red, utilize these SKU codes:
  • PWB-111
  • PWP-112
  • PWW-113
  • PWR-114
  • Avoid repeating the same letter within a single code.
  • Refrain from using special characters.
  • Organize your SKU numbers and codes based on their significance.
