Do car seats really expire?

Yes. Every car seat has a useful life set by its manufacturer, usually 6 to 10 years from the date of manufacture. The expiration is printed on the seat itself or in the instruction manual. It is not a marketing trick: plastics, harness webbing, and foam all degrade over time, and safety standards keep improving.

Where do I find the manufacture date on a car seat?

Look for a white sticker or embossed stamp labeled Date of Manufacture or DOM on the bottom, back, or side of the seat or its base. Many brands also print the expiration date directly on the same label. If the seat was registered, the manufacturer can also confirm the dates from the model and serial number.

When do Graco car seats expire?

Graco seats last 10 years from the manufacture date unless the label says otherwise; most Graco infant seats expire after 7 years. Check the sticker on the bottom or back of your specific seat, because the exact lifespan varies by model.

When do Britax car seats expire?

Britax infant seats expire 6 years after manufacture, Harness-2-Booster seats last 9 years, and ClickTight / all-in-one seats plus 2-stage and backless boosters last 10 years. Find the date of manufacture using the serial number and instruction manual, then add the lifespan for your seat type.

When do Chicco car seats expire?

Chicco lifespans run 6 to 10 years depending on the seat type: infant seats last 6 years, rotating convertible seats, harness booster seats and booster seats last 8 years, and all-in-one seats last 8 or 10 years. The expiration date is printed on both the seat and the base, so check each piece separately if you use a travel system. When the seat type is unknown, 8 years is a conservative default.

When do Evenflo car seats expire?

Most Evenflo car seats expire 6 years after manufacture. Exceptions: the Symphony, Transitions, and Evolve 3-in-1 lines last 8 years, and SafeMax models last 10 years. The DOM label is on the back, bottom, or side of the seat.

What happens if I keep using an expired car seat?

An expired seat may not protect your child in a crash. Heat, cold, sunlight, and humidity make the plastic shell brittle, metal parts can develop hidden rust, harness webbing weakens, and replacement parts are no longer made for discontinued models. Safety standards also move on, so an old seat no longer reflects current best practice.

Is it illegal to use an expired car seat?

In most places there is no law that makes it a ticketable offense the day after expiration, but child restraint laws require a proper, approved restraint, and using a seat against the manufacturer's instructions can violate that requirement. It can also affect insurance and liability after a crash. The safe answer is to replace the seat.

Can I use a second-hand car seat?

Only if you can verify its full history: it must be within its expiration date, never have been in a moderate or severe crash, come with all original parts and the manual, have no cracks or damage, and not be subject to a recall. If any of those are unknown, do not use it. Use the second-hand checklist tab above to score a used seat.

Does a car seat expire after a crash?

A car seat involved in a moderate or severe crash must be replaced immediately, even if it looks fine and is nowhere near its expiration date. Hidden structural damage can make it fail in the next crash. Only a very minor crash, as defined in your manual, may allow continued use. When in doubt, replace it.

Do booster seats expire too?

Yes. Booster seats follow the same 6 to 10 year rule; for example, Diono boosters last 10 years and most Britax belt-positioning boosters last 10 years (the Britax Harness-2-Booster lasts 9 years). The plastic and belt guides degrade just like a harnessed seat, so check the label the same way.

Is expiration counted from the purchase date or the manufacture date?

Always from the date of manufacture, not the purchase date. A seat can sit in a warehouse or store for a year before you buy it, and that year counts. This is why the manufacture date sticker matters more than your receipt.

How do I dispose of an expired car seat?

Destroy it first so nobody else uses it: cut the harness straps, remove the cover, and write DO NOT USE - EXPIRED on the shell with a permanent marker. Then check manufacturer or retailer trade-in and recycling programs, which often give a discount on a new seat.

What if the manufacture label is missing or unreadable?

Treat the seat as expired and do not use it. Without the DOM you cannot prove the seat is within its useful life, and a missing label often means heavy wear or tampering. Contact the manufacturer with the model number and serial number. If they cannot confirm the dates, replace the seat.

Worked example: Graco seat made in January 2020

Read the DOM label. The white sticker on the back of the seat says Date of Manufacture: January 2020.
Find the brand lifespan. Graco seats last 10 years from manufacture unless the label says otherwise (most Graco infant seats: 7 years). We use 10 years.
Add the lifespan to the manufacture month.
Expiration = January 2020 + 10 years = January 2030
Count the remaining months from the check date (October 2026).
Remaining = (2030 − 2026) × 12 + (1 − 10) = 48 − 9 = 39 months = 3 years 3 months
Apply the status rule. The seat is expired when remaining < 0, and "expiring soon" when 0–5 months remain. 39 months ≥ 6, so the status is VALID with 3 years 3 months to go.

Two more quick examples (checked as of October 2026)

Example B — expired seat. Evenflo convertible, manufactured March 2019, 6-year lifespan → expires March 2025. Remaining = (2025 − 2026) × 12 + (3 − 10) = −12 − 7 = −19 months. Status: EXPIRED — 1 year 7 months overdue. Replace immediately and destroy the old seat.

Example C — valid seat. Chicco seat, manufactured June 2021, 8-year lifespan (the conservative default for an unknown Chicco seat type) → expires June 2029. Remaining = (2029 − 2026) × 12 + (6 − 10) = 36 − 4 = 32 months. Status: VALID — 2 years 8 months to go.

Why do car seats expire?

Expiration dates exist for engineering reasons, not to sell more seats:

Plastic degrades. Heat, cold, sunlight, and humidity make the shell brittle over years of daily use — including time parked in a hot car.
Metal fatigues and rusts. Buckles, anchors, and internal hardware can corrode in places you cannot see.
Webbing and foam wear out. Harness straps are washed, twisted, and tensioned thousands of times; energy-absorbing foam compresses.
Parts disappear. Once a model is discontinued, replacement parts stop being manufactured.
Standards move forward. Crash-test knowledge and best-practice recommendations improve every few years; expiration guarantees your seat is not decades behind.
Recalls get missed. An expiration date bounds how long an unregistered, possibly recalled seat can stay in service.

Where to find the manufacture date, by brand

Brand	Where the DOM / expiration label is
Graco	Sticker on the bottom or back of the seat.
Britax	Use the serial number with the instruction manual; expiration rules depend on seat type and production date.
Chicco	Printed on both the seat and the base.
Evenflo	DOM label on the back, bottom, or side of the seat.
Baby Trend	Underside of the seat or bottom of the base.
Diono / others	Usually embossed or stickered on the back or underside — check the manual's "labels" diagram.
