Yes, baby car seats have expiration dates, typically between 6 to 10 years from the date of manufacture. Using an expired car seat is a significant safety risk. The primary reasons for expiration are the degradation of plastic and other materials over time due to temperature fluctuations and exposure to sunlight, which can cause the seat to crack or fail in a crash. Additionally, safety standards and technology evolve, meaning an older seat may lack critical safety improvements.
You can find the expiration date stamped on the plastic shell of the seat, often on the back or bottom. It might also be printed on a sticker with the model number and manufacturing date. Most manufacturers also include it in the owner's manual. If you cannot locate it, contact the manufacturer directly with the model number.
| Reason for Expiration | Key Considerations | Typical Industry Guideline |
|---|---|---|
| Material Degradation | Plastics become brittle and may not withstand crash forces. | 6-10 years |
| Outdated Safety Standards | Lacks newer features like side-impact protection. | Varies by model year |
| Missing Parts/Instructions | Increases risk of improper installation. | Check immediately |
| Recall History | Older models may have unresolved safety recalls. | Check NHTSA website |
Never buy a used car seat unless you know its full history and can confirm it has never been in an accident. If a seat has been in a crash, even a minor one, it should be retired immediately, as its structural integrity is compromised. When a seat expires, the best practice is to dismantle it (following the manufacturer's instructions to prevent reuse) and dispose of it, often through a recycling program if available. Your child's safety is paramount, and an up-to-date, properly installed car seat is your first line of defense.

As a parent of three, I treat the car seat expiration date like the one on a gallon of milk. You just don't risk it. That plastic gets baked in the car summer after summer, and it gets weak. I mark the expiration date on my calendar with a reminder a few months out so I'm ready to shop for a new one. It's not a marketing gimmick; it's about making sure that seat will do its one job perfectly if we ever need it to.
