Where the expiration date is printed on a car seat

The expiration date is stamped or printed directly on the plastic shell of the car seat itself — usually on a label attached to the bottom, back, or side. You do not need to open the seat or remove padding to find it. The label is typically white or silver with black text, and it will say something like "Do Not Use After" followed by a month and year.

On some seats, the date appears on a sticker on the underside where the seat contacts your vehicle. On others, it is on the back panel. Flip the seat over or rotate it to check all surfaces. The manufacturer's name and model number are usually on the same label, so once you spot those, the expiration date will be nearby.

If the label has worn away or is unreadable, check the instruction manual that came with the seat — it will list the manufacture date and the expiration date. You can also contact the manufacturer directly with your seat's model number, and they can tell you when it expires.

Key Takeaways

  • The expiration date is printed on a label attached to the car seat's plastic shell, usually on the bottom, back, or side panel.
  • Car seats typically expire 6 to 10 years from the manufacture date, depending on the brand and model.
  • An expired car seat should not be used, even if it appears to be in good condition, because the plastic degrades over time.
  • If you cannot find the label, the instruction manual or the manufacturer can confirm the expiration date using the model number.

Why car seats have expiration dates

Car seats expire because the plastic shell and foam padding break down over time, even when the seat is not being used. Heat, cold, sunlight, and humidity all cause the materials to become brittle and less able to absorb impact in a crash. A seat that looks fine on the outside may have internal damage that you cannot see.

The expiration date is set by the manufacturer based on testing of how long their specific materials hold up. Different brands use different plastics and foams, so expiration dates vary — some seats expire after 6 years, others after 10. The date is not arbitrary; it reflects when the seat is no longer safe to rely on.

What to do if your car seat has expired

Stop using the seat when ready. An expired car seat does not meet current safety standards and will not protect your child the way it is designed to. Even if you are only driving a short distance or at low speeds, the risk is real.

You will need to purchase a new car seat. If cost is a concern, look for programs in your area that distribute free or low-cost seats — many hospitals, fire departments, and nonprofits run these programs. You can also check whether your insurance covers car seat replacement.

Do not donate or pass along an expired seat to someone else. Some people do, but it puts another child at risk. If you want to dispose of the old seat, contact your local waste management or recycling center to ask how to do so safely.

How to check the manufacture date if you only see one date

Some labels show only the manufacture date, not the expiration date. In that case, you need to add the manufacturer's stated lifespan to find when it expires. For example, if the seat was made in January 2018 and the manufacturer says the seat lasts 10 years, it expires in January 2028.

The instruction manual will tell you the lifespan for your specific model. If you do not have the manual, search the manufacturer's website using the model number, or call their customer service line. They can tell you both the manufacture date and how many years the seat is good for.

Reading the date format on the label

Manufacturers use different date formats, so the label may show the date as "01/2025" (month/year), "2025-01" (year-month), or written out as "January 2025." Some labels say "Manufactured" or "Made" with one date, and "Do Not Use After" with another. Read the label carefully to make sure you are looking at the expiration date, not the manufacture date.

If the format is unclear or the printing is faded, take a photo of the label and email it to the manufacturer's customer service. They deal with this question regularly and can confirm the date for you within a day or two.

Keeping track of your car seat's expiration date

Write the expiration date on your calendar or phone as soon as you install the seat. This way you will not forget and accidentally use an expired seat. If you have multiple children or plan to use the same seat for a second child, set a reminder a few months before the expiration date so you have time to purchase a replacement.

If you are buying a used car seat, always check the expiration date before using it. A used seat may be close to expiring even if it looks new. If it is within a year or two of expiration, it is usually not worth buying because you will need to replace it soon anyway.

Frequently Asked Questions

Can I use a car seat after the expiration date if it looks fine?

No. The plastic and foam degrade internally even when the seat looks undamaged. The expiration date is when the manufacturer can no longer may provide the seat will protect your child in a crash. Using an expired seat puts your child at risk, regardless of how new it appears.

Where exactly should I look on the car seat for the label?

Start with the bottom of the seat where it touches your vehicle, then check the back panel and the sides. The label is usually a white or silver sticker with black text. If you cannot find it after checking all surfaces, flip the seat over or consult the instruction manual for the exact location on your model.

What if I bought a used car seat and the label is missing?

Contact the manufacturer with the model number and serial number if visible. They can look up the manufacture date and tell you when it expires. If you cannot find the model number or the manufacturer is no longer in business, it is safer to replace the seat rather than guess about its age.

Do car seats expire if they have never been used?

Yes. The materials degrade over time regardless of whether the seat has been installed or used. A brand-new car seat that was manufactured 8 years ago and never opened is still subject to the same expiration date as one that has been in daily use.

Can I extend the life of my car seat past the expiration date?

No. The expiration date is not a suggestion or a guideline — it is the point at which the manufacturer can no longer may provide the seat's safety. Once that date passes, the seat should be replaced, not repaired or refurbished.
