Is there a maximum length for an SKU?

Yes, there is typically a maximum length for an SKU (Stock Keeping Unit) in order to maintain efficient inventory management and ensure compatibility with various systems. The specific length may vary across industries and organizations, but it is common for SKUs to range between 8 and 12 characters. Shopify has a limit of 16 characters. This allows for a balance between uniqueness and practicality, accommodating alphanumeric codes and facilitating quick identification and retrieval of products.
