Platforms' management of codes is moving from "just fill it in" toward "verifiable and traceable." This direction is actually good for businesses operating legitimately.
In the early days, platforms mainly verified whether the number of digits and the check digit of a code were valid, which was a formal check. In recent years, the direction has been to focus more on "is this code yours"—some categories require proof of code ownership, or verify the relationship between the code and the store entity. This means that "a valid number" is no longer enough, and "clear ownership" has become a new threshold.
As platform data capabilities improve, cross-channel product data comparison becomes possible. When the same code appears across multiple channels, whether product information is consistent and whether specifications correspond will be included in data quality considerations. This is favorable for businesses operating legitimately—it squeezes the space for profiting from information opacity.
Another direction is moving compliance from post-event review forward to process management: requiring product information to remain consistent throughout the entire listing and delisting process, and paying more attention to products that repeatedly change codes or information. This means that "filling it in correctly at listing" is no longer enough, and "continuously keeping it correct" is equally important, which increases the value of code ledgers.
Three directional suggestions:1.Keep code ownership documents (membership credentials, code segment allocation documents) as regular archives rather than looking for them on an ad hoc basis;II.Establish and maintain a code ledger to ensure the same SKU uses the same code across all channels;III.Keep entity information consistent with registered information, and when the entity changes, update the platform and code registration simultaneously. These three things are not costly, but when reviews tighten, they will significantly reduce communication costs.
E-commerce platform rules are adjusted frequently. This page only describes observed directions, does not cite specific clauses, and does not constitute a commitment regarding platform rules. For actual operations, please refer to the current version of each platform's official documentation.
Key conclusions that can be excerpted directly.
A valid number is only the first step; clear ownership is also a concern.
Information consistency of the same code across multiple channels will be taken into consideration.
Filling it in correctly at listing is not enough; keeping it correct continuously is equally important.
Ownership document archiving, code ledgers, and ongoing information consistency maintenance.
| Trend direction | Past practice | Current direction |
|---|---|---|
| Code verification | Check digit and check character | Add ownership verification and entity relationship checks |
| Data scope | Product data within a single platform | Cross-channel product information consistency comparison |
| Management timing | Mainly listing review | Process management covering the entire listing and delisting workflow |
| Requirements for enterprises | Just fill it in correctly at listing | Continuously keep codes and information correct |
