Where the Number Comes From
A serial number, starting from 001, one number per record, not repeated, not recycled.
The number is written on the tag and appears in the same frame as the lamp when photographed. So what you see is not an edited video, but an object that can be identified.
The Role of the Verification Code
A number alone is not enough for lookup—otherwise anyone could browse others' records.
Therefore, each record is issued a separate six-digit verification code, printed on the order confirmation letter and the number card. Both must be entered for lookup; neither can be omitted.
What You Will Receive
How to Verify
Three steps: the number matches your order, the timestamp of the image matches the placement date, and the item in the picture matches what you purchased.
If any one of the three does not match, a full refund is given. This is not marketing rhetoric; it is a clause written in the terms of service.
Why Do It This Way
The most common problem in this industry is not 'ineffectiveness,' but 'unverifiability': the same photo used many times, someone else's site passed off as one's own, money collected without actually going.
Numbering plus timestamps cannot solve all problems, but it makes 'pretending to have done it' difficult. For us, this is more practical than any promise.
