Dior's batch number is usually printed on the bottom of the product or the bottom of the outer box packaging, and the hose is pressed at the end of the hose. Dior's four-yard lot number depends on the first and second digits.

The first digit indicates the year, and the last digit indicates the number.

The second number represents the month, and there are two letters for shorthand every month. 65438+ October =A, N, February =B, P, March =C, Q, April =D, R, May =E, S, June =F, T, July =G, U, August =H, V and September =J, W, October.

For example, "0U0 1" means production in July 2020.
