How to Check the Production Date on the Car's Front Windshield?

Methods to check the production date on the car's front windshield: 1. The production date of the car glass can be identified by a code located at the bottom left or right corner of the windshield. Look for a number and several small black dots in the last or second-to-last row; 2. The number represents the production year of the glass, indicating the last digit of the year. The production date of the glass and the vehicle will not differ by more than 10 years; 3. The small black dots indicate the production month. If the dots are before the number, subtract the number of dots from 7. If the dots are after the number, subtract the number of dots from 13; 4. Some glass may also have a few larger black dots following the production year and month, which specify the week of the month. For example, 5 dots represent the first week, 4 dots the second week, and 3 dots the third week.
When I changed my car the year before last, I really wanted to know the windshield date because I was worried about being scammed when buying a used car. The person who taught me said to look at the corners of the glass from outside the car after parking, usually searching for dots or numbers in the bottom left or right corner. The dots represent the year position: 10 dots correspond to 2010, and the fewer the dots, the newer the year. For example, 7 dots mean 2007. If you see something like '11.', it indicates 2011. It's clear in sunlight, and you can use a phone light in poor lighting. Learning this is very convenient—it takes just five minutes to master, and it can prevent sellers from deceiving you. Now I always use this trick when checking cars; it's as practical as a handy little tool. If you can't find it, I recommend checking the owner's manual or asking the salesperson, as glass aging affects safety, and knowing the manufacturing year early can help you estimate its lifespan.
