Direct definitionBM3, BM5, and BM10 are common Chinese-market labels for BM capacity. They may refer to ad accounts that can be created, are already included, or can be managed, or simply to a seller-defined product tier.
What this term usually means
- The most common interpretation is the number of ad accounts in a BM or its capacity level.
- The same BM3 can mean “three included accounts,” “three accounts can be created,” or “three accounts can be shared,” depending on the supplier page.
- Verify the specific BM, relationship type, ad-account list, and currently visible status separately.
What this term cannot establish
- BM3/BM5/BM10 alone cannot establish limit, ownership, or stability.
- Shared access is not the same as a complete asset transfer.
- A listed capacity must be checked against the current Meta page.
How to verify it in practice
Industry shorthand can speed up discussion, but final decisions must return to the current page, actual relationship and explicit delivery scope.
- Review the number of currently visible ad accounts
- Confirm whether the relationship is ownership, sharing, or authorization
- Record the verification date and current page result
Why separate verification matters
Supplier names often compress the object, state, use, quality claim and support terms into one label. Checking each part reduces conflicting expectations.
