A familiar company name on a B2B store page is not sufficient to prove that the page belongs to the supplier. This article defines three verification checks: whether the company name matches, whether the registration number matches, and whether the contact lines agree with the supplier’s own contact page. A full match supports Case 1; a name-only match is Case 2 and requires clarification; an account operated by a dealer or reseller is Case 3. For MILDTRANS, two Alibaba International accounts are stated for the two legal entities, while the live registration number and contact lines remain unread until the buyer opens and compares the relevant pages. An unread item is a pause, not proof of ownership or reseller status.

Certificate coverage must be read from the product names printed on the paper, not from a supplier’s sales catalogue. This article defines three readings: the needed category is named; a related category such as adapters is named while batteries are absent; or the document names no product-level test and is only a quality-system paper. The cited EMC and RoHS file names nine product categories and includes an LVD test to IEC 62368-1 for laptop adapters, but it is held by Shenzhen Glory Energytech Co., Ltd., not MILDTRANS. A battery buyer therefore remains in the related-category-only case and must request a battery-specific file.

A confident sales call should not be treated as completed supplier verification. This article defines three independent layers: matching the registration name with the invoice name, opening the platform mark on a live page, and testing the buyer’s own physical sample. Three completed layers form the strongest base in this method, but they are not certainty. One objectively missing layer may remain acceptable when it is clearly named, while a direct failure on any layer keeps the file high risk. Commercial lines such as outbound timing, MOQ, payment terms, DOA timing and country counts sit beside the three-layer count and do not add another verification layer.
