This is general product research, not a substitute for your car seat’s manual or a car seat inspection. If you’re unsure whether a seat is still usable, contact the manufacturer.
Short answer: A car seat expiration date is the date of manufacture plus the manufacturer’s stated useful life — 6 to 10 years for the brands we checked, depending on the seat type. Find the date of manufacture on the seat’s label, then check the label or manual for how many years apply.

| Brand and seat type | Stated useful life | Calculation | Example: made March 2026 |
|---|---|---|---|
| Graco — plastic-reinforced belt path seats | 7 years | Date of manufacture + 7 years | March 2033 |
| Graco — steel-reinforced belt path seats and belt-positioning boosters | 10 years | Date of manufacture + 10 years | March 2036 |
| Britax — Arbor infant seat and StayTight infant base | 6 years | Date of manufacture + 6 years | March 2032 |
| Britax — Grow With You harness-2-booster seats | 9 years | Date of manufacture + 9 years | March 2035 |
| Britax — Poplar, Galaxy360, One4Life, Highpoint, Skyline, UpNGo | 10 years | Date of manufacture + 10 years | March 2036 |
| Chicco — varies by seat type and model | 6 to 10 years | Date of manufacture + the years in your manual | March 2032 to March 2036 |
Researched: useful-life periods come from Graco’s car seat expiration page, Britax’s expiration guide, and Chicco’s lifespan page, checked in September 2026; the March 2026 examples are our arithmetic, and brands we couldn’t confirm from an official source are left out.

Where to Find a Car Seat Expiration Date
Start with the label. NHTSA’s used car seat checklist says a seat should have labels stating the date of manufacture and model number — you need both to check for recalls and to tell whether the seat is too old. Britax’s guide goes a step further and lists where the serial label sits on each of its models, with every expiration measured from the date of manufacture printed there. If you can’t find the label, the seat’s manual is the next place to look.
If the label shows only a date of manufacture, do the math the way Graco’s own example does: date of manufacture plus the seat’s useful life equals the expiration date. Graco’s page walks through a booster made on March 15, 2020, with a 10-year useful life, expiring on March 15, 2030.
One detail catches people out. The car seat expiration date counts from the day the seat was made, not the day you bought it. A seat that sat in a warehouse or a store for months has already used part of its life before it reaches your car.
Why the Same Brand Can Have Different Dates
The table shows why you can’t assume one number per brand. Graco sets 10 years for seats with a steel-reinforced belt path and for belt-positioning boosters, but 7 years for seats with a plastic-reinforced belt path. Britax ranges from 6 years for its Arbor infant seat and StayTight base to 10 years for most of its convertibles and boosters. Chicco describes a 6-to-10-year range depending on the seat.
So two seats from the same brand, bought the same week, can expire years apart. That matters most with hand-me-downs and with families using several seats at once — an infant seat and a booster from the same brand won’t necessarily retire together.
Before You Use a Hand-Me-Down Seat
A car seat expiration date is only one of NHTSA’s checks for a used seat. Its checklist also asks that the seat has no open recalls and hasn’t been in a moderate to severe crash, and that you have the labels needed to look it up. If any of those can’t be confirmed, the safer move is a seat whose history you know.
If you’re weighing an infant seat against a convertible for the next stage, our infant vs convertible car seat guide covers how the two differ, and our 3 car seats across guide helps when an expiring seat means replacing one position in a full row.
The quick version: find the date of manufacture, find the seat’s useful life in the label or manual, add them, and write the car seat expiration date somewhere you’ll see it — a note on the seat itself or in your phone’s calendar works.
