Do Car Seats Expire? Where to Find the Date, and What to Do With an Old One
October 12, 2026
The short answer
Yes. Every car seat has a manufacture date on its label, and the manufacturer sets how long the seat can be used from that date. The expiration date or the lifespan is printed on a label, molded into the plastic shell, or listed in the manual. Count from the date it was made, not the date you bought it.

Yes, car seats expire. It sounds like a marketing trick to sell you a second one. It isn’t. The manufacturer decides how long it will stand behind the seat, and after that date you’re on your own.
Where the date actually is
Flip the seat over or look along the sides of the shell. You’re looking for two things:
- The manufacture date. It’s on the white label with the model number. The American Academy of Pediatrics tells parents to start here: find the date the seat was made, then check with the manufacturer for how long it recommends using it.
- The expiration date or lifespan. Some seats print a “do not use after” date. Some mold it into the plastic shell. Some only say “use for X years from date of manufacture” in the manual.
If you can’t find either, the manual will tell you, and most manufacturers put manuals online. Search the brand plus the model number from the label.
How long is “a while”?
It depends on the seat. Lifespans commonly run somewhere around six to ten years from the manufacture date, and assuming the long end is how people get it wrong. Don’t guess. Read the label.
Two things that trip people up:
- The clock started at the factory. Not at the baby shower. A seat that sat on a shelf for a year has a year less left.
- Infant seats and convertibles are different. An infant bucket is usually outgrown long before it expires. A convertible bought for a newborn might be asked to last until kindergarten or beyond, so its date matters a lot more.
Why this matters most for hand-me-downs
A brand-new seat from a store is almost never the problem. The problem is the seat your cousin used for two kids and kept in the garage. Before you accept a used seat, find the date. If it will expire before your kid outgrows it, it’s not a gift. It’s a deadline.
Expiration is only one of the checks for a used seat. The others are in is a used car seat safe?.
Also: register the seat
There’s a registration card in the box. Fill it out, or register on the manufacturer’s site. That’s how they reach you if the seat is recalled. You can also look up recalls yourself on NHTSA’s recall site. It takes two minutes and it’s the one bit of baby paperwork that’s actually worth doing.
What to do with an expired seat
Don’t sell it and don’t donate it. Someone will use it. Cut the harness straps, write “EXPIRED” on the shell in marker, and throw it out or recycle it if your area takes the plastic. Some big retailers run car seat trade-in events now and then; if one lines up with your timing, use it.
If you’re not sure
Take it to a car seat check. Techs look at the date and open recalls as part of the visit. Find a car seat inspection station near you, and bring the manual.

- Bulkier than an infant-only seat in month one
- Heavier to carry between cars
Follow-up questions
How long are car seats good for?
As long as the manufacturer says, counted from the date of manufacture on the seat's label. Lifespans commonly land somewhere around six to ten years, but that is a pattern, not a rule. Your seat's label or manual is the only number that counts.
Does the clock start when I buy the seat?
No. It starts on the manufacture date printed on the label. A seat that sat in a warehouse for a year has a year less left on it.
Can a car seat technician check the expiration date for me?
Yes. Checking the date and open recalls is a normal part of a car seat inspection. Bring the seat and its manual.
