To save money, many sellers link the same RFC tax number—which is registered under a single entity—to multiple stores. Before the tax reform, this was indeed a fairly common practice—it saved costs and made management more convenient.

However, following the 2026 tax reform, the underlying logic behind this approach has changed.

01 First, let’s get this straight: How do platforms identify “one account, multiple stores”?”

The Meikeduo platform identifies "one account, multiple stores" based on two criteria:

1. Direct Connection for Tax ID Numbers: Each store’s linked RFC tax ID has a unique ID in the SAT system, which the platform compares directly. If the same tax ID appears across multiple stores, the system automatically flags it.
2. Cross-Checking Data: The platform not only checks tax ID numbers but also cross-checks information such as legal representative details, registered addresses, payment accounts, and IP login addresses. Even if the tax ID numbers differ, a high degree of overlap across other dimensions will trigger an affiliation review.

Following the tax reform, the comparison of these two dimensions shifted from “periodic spot checks” to “real-time monitoring.”

02 How Significant Is the Risk of Having Your Store Shut Down?

This isn't a “matter of probability,” but rather a “chain reaction.”

Once any store under the same tax ID triggers a KYC review, tax anomaly, or risk control violation, all stores under that tax ID will be flagged as “associated risk.” The platform’s logic is that since these stores share the same tax ID entity, they are considered a single business entity.

Real-world scenarios: You have three stores listed, and one of them has been restricted from selling by the platform due to a high return rate—the other two stores will also receive risk control notifications at the same time. It’s not a matter of “only one being suspended,” but rather “all of them being suspended.”

03 There are three additional associated risks

Risk 1: A Chain Reaction of Fund Freezes

Once a store is suspended due to association with another store, payments for all associated stores are simultaneously restricted. Funds in the accounts cannot be withdrawn, and the appeal process is several times more complicated than for a single store—you must provide separate compliance evidence for each store at the same time.

Risk 2: The appeal approval rate is extremely low

Once you’ve been classified as a “single entity operating multiple stores,” you’ll need to prove during the appeal process that each store is an independently operated entity—but this is inherently contradictory, since you’re using the same tax ID number. The platform will not accept explanations such as “We just share the same tax ID number.”

Risk 3: Permanent Ban Record

After a store is shut down due to association with a tax ID, a permanent mark will be left on that tax ID holder’s credit record on the platform. Even if you register a new company or obtain a new tax ID in the future, the platform’s cross-checking of legal representative identities and IP addresses may affect the approval process for your new store.

04 What should I do if I already have multiple stores under the same account?

If your store is currently operating normally, we recommend separating it as soon as possible:

1. Core stores should retain their affiliated tax ID numbers and plan a path to upgrade to their own tax ID numbers as soon as possible.
2. Temporarily reduce the operational activity of non-core stores to lower the likelihood of being flagged for review.
3. After upgrading to your own tax ID, gradually link your stores to that tax ID to achieve a true “one tax ID, one store” system.”

Core Principle: Don’t put all your eggs in one tariff code basket. Once associated risks are triggered, it’s not just one store that suffers—it’s all of them.
