What is a SKU number? A SKU number is an internal product identifier that a business uses to organize, search, sell, and report on products. It is usually created by the company that manages the catalog, not by a universal standards body.
For furniture distributors, the SKU number matters because supplier catalogs often arrive as PDFs, Excel price sheets, images, and mixed product lists. A clean SKU connects the product name, supplier, dimensions, material, finish, price context, image, and source evidence.
What Is a SKU Number?
A SKU number is a stock keeping unit code used inside a company to identify a product or variant. It can include letters, numbers, and segments that represent supplier, category, material, color, size, or sequence.
In practice, "what is sku number", "what is an sku number", and "what is the sku number of a product" all point to the same idea: a SKU is the internal product code that helps a team find the right item.
SKU Number Format
A useful SKU number format should be easy to read, stable, and specific enough to separate variants.
Example format:
| Segment | Meaning | Example |
|---|---|---|
| Supplier | Vendor or factory | ACM |
| Category | Product family | CHR |
| Material | Material or finish | OAK |
| Variant | Color, size, or set count | LGY |
| Sequence | Unique row number | 001 |
Example SKU number: ACM-CHR-OAK-LGY-001
How Many Digits Is a SKU Number?
There is no required SKU length. A SKU number can be short or long as long as it is unique inside your catalog. Many teams prefer segmented codes because they are easier to read than a single long number.
For furniture teams, avoid encoding too much detail into one SKU. Keep the most useful fields in the SKU and store the rest as structured product attributes.
Where to Find a SKU Number
You can find a SKU number in supplier catalogs, Excel price sheets, marketplace listing settings, inventory exports, product labels, or internal product records.
Supplier files may use other labels, including item number, model, product code, article number, supplier code, or order code. Use the SKU Number Locator when you need a platform-by-platform lookup flow for Walmart, Amazon, Shein, Shopify, Etsy, and supplier catalogs.
How to Create a SKU Number
Start with the product data your team actually uses to identify items:
- Choose stable segments such as supplier, category, material, variant, and sequence.
- Keep each segment short and readable.
- Avoid spaces and special characters.
- Make sure each SKU is unique inside the catalog.
- Store the original supplier source beside the final product record.

SKU Number vs UPC vs Serial Number
A SKU number is internal to a business. A UPC is a standardized retail barcode identifier. A serial number identifies one individual physical item.
For example, all chairs in one finish may share the same SKU, while one specific chair unit may have its own serial number. Read more in SKU vs UPC and SKU vs Serial Number.
