Why is there no date on the seat belt?

[MadelynDella]

Pull out the entire seat belt, and at the very bottom, there is an attached label with the production date of the seat belt. Seat belt date coding: It should be noted that some seat belts directly display the date, which is very obvious and can be seen at a glance. However, some seat belts have labels that are cluttered with English text, making it difficult to identify the date at first glance. In such cases, if you find English letters like 'MFDDATE', the following information is the production date, as 'MFDDATE' stands for manufacturing date. 17-digit coding rule: Another point to note is that if 'MEDDATE' is followed by a combination of letters and numbers, it indicates the use of the 17-digit coding rule, which is related to the Vehicle Identification Number (VIN code). The tenth digit of the VIN code is associated with the date, cycling every 30 years.
