Sku Generator

Businesses wishing to accurately track inventory often use a sku generator to assign individual identification codes to products. Skus, or stock keeping units, are unique internal product identifiers that can be scanned to relay information to inventory software about the product name, description, quantities, components, costs, etc. UPC codes, on the other hand, are universal product codes assigned to manufacturers’ products by GS1 US. Their numbers remain constant even when product is transferred to the wholesalers and retailers who sell their products. Sku numbers will vary from one business to another, even for the same product, because they are business specific.

When sku numbers are affixed to stock, they can comprise letters and numbers or appear as varying thick and thin parallel lines typical of barcodes. When scanned, they transmit the tracking number set up by the barcode sku generator. The sku number may contain references to manufacturer, description, model, material, size, color, packaging, and warranty terms.

SKU Number Generator FAQs

How are SKU numbers different from UPC or barcode numbers?

SKU numbers and UPC (Universal Product Code) or barcode numbers serve different purposes in the retail industry. A SKU number is an internal code created and used by retailers to manage their inventory and track products within their system. It provides more detailed information about the product, such as variations in size, color, or style.

On the other hand, UPC or barcode numbers are standardized codes that are assigned to products by manufacturers and are used for universal identification of products at the point of sale. They contain information such as the manufacturer’s identity and a unique product identifier. Barcode numbers are typically scanned at the checkout counter to retrieve product information and facilitate sales transactions.

Why are SKU numbers important?

SKU numbers play a crucial role in effective inventory management and retail operations. Here are some reasons why they are important:

Accurate tracking: SKU numbers enable retailers to track individual products accurately, allowing for better control over inventory levels, reducing the risk of stockouts or overstocking.

Efficient inventory management: By assigning unique SKU numbers to products, retailers can categorize and organize their inventory more effectively. This makes it easier to locate products, manage stock rotations, and optimize replenishment processes.

Sales analysis: SKU numbers enable retailers to analyze sales data at a granular level. By associating each sale with a specific SKU number, retailers can identify top-performing products, track trends, and make data-driven decisions about pricing, promotions, and product assortment.

Enhanced customer experience: With SKU numbers, retailers can quickly locate and fulfill customer orders, reducing delivery times and ensuring a smoother shopping experience.

How Sku Generation Empowers Inventory Management

How to Create a Sku

The best inventory management technique for developing industry skus entails using numbers unique to your business, avoiding the manufacturer’s or wholesaler’s tracking numbers. The sku is comprised of letters and numbers – the shorter the string the easier to manage. Meaningful skus can be helpful and common abbreviations for colors and sizes are often used. Dashes can separate different elements of the sku.  Avoid using punctuation characters which may not be recognized when scanned.
