AliExpress SKU Coding Rules and Filling Guide

What is the SKU coding rule on the AliExpress platform? How to fill in the SKU code?

In the field of e-commerce, SKU Stock Keeping Unit coding is one of the important tools for product management. For AliExpress sellers, understanding and correctly filling in the SKU code can not only improve the efficiency of store operations but also effectively avoid order problems caused by information errors. So what exactly are the SKU coding rules on the AliExpress platform? How to accurately fill in the SKU code? This article will provide a detailed interpretation from multiple perspectives and offer references for readers through relevant cases and news reports.

First, we need to clarify what an SKU code is. Simply put, an SKU code is a code used to uniquely identify a specific product and its attribute combinations. It is usually composed of letters, numbers, or a combination of both, with the aim of helping merchants quickly identify and manage various products in inventory. For cross-border e-commerce platforms like AliExpress, a reasonable SKU coding system can enhance the professionalism of product displays and help consumers better understand the details of the products they purchase.

So, what are the specific requirements for SKU codes on the AliExpress platform? According to official guidelines, each product must have a unique SKU code, which needs to follow these principles

1. The length of the SKU code cannot exceed 60 characters;

2. The code should include English letters and Arabic numerals but must not use special symbols;

3. Different product specifications or attribute combinations require different SKU codes;

4. The SKU code should be intuitive and easy to remember for buyers to view and select.

Next, let's look at how to correctly fill in the SKU code. Typically, a complete SKU code should include several parts brand name abbreviation + main category + subcategory + color + size, etc. For example, ADIDAS-SHOES-BASKETBALL-RED-M clearly indicates that this product is an Adidas basketball shoe, red in color, and M in size. Such a coding method complies with platform regulations and facilitates subsequent data tracking and inventory management.

It is worth noting that in actual practice, many novice sellers often encounter common pitfalls when filling in SKU codes. For instance, some people tend to use simple serial numbers instead of descriptive codes, thinking it saves time; others add too many decorative symbols for aesthetics, violating platform rules. In response to these issues, the China E-Commerce News once pointed out that reasonably designing SKU codes not only enhances user experience but also serves as the foundation for internal process optimization within enterprises. It is recommended that sellers always balance practicality and standardization when formulating SKU coding strategies.

With the rapid development of the cross-border e-commerce industry in recent years, more and more brands have begun to attach importance to using data analysis to guide business decisions. For example, a well-known clothing brand introduced a smart SKU generation algorithm based on big data analysis into its global supply chain management system, achieving the goal of accurately predicting market demand and dynamically adjusting inventory levels. This successful case reminds us that in daily operations, besides focusing on basic operational skills, we should actively embrace new technologies to continuously enhance our competitiveness.

To sum up, although the SKU coding rules on the AliExpress platform may seem simple, they actually contain rich connotations. Whether from the perspective of meeting platform review standards or long-term development, mastering the correct method of SKU coding is particularly important. It is hoped that the information provided in this article will inspire sellers and help them stand out in fierce market competition. Finally, I would like to emphasize again no matter when or where, always adhere to the principle of putting customers first, and do every small thing with heart. I believe your efforts will eventually bear rich fruit!
