How to Find Expiration Date of a Car Seat

You are not looking for a hidden code. You are looking for one safety deadline that tells you when that child restraint leaves its tested use period.

The confusing part is location. One car seat prints the expiration date on a white label. Another stamps it into the plastic shell. A third gives only the date of manufacture and asks you to calculate the date from the manual.

This takes about 9 minutes to read. Start with the label, then confirm the date against the manual before you keep, sell, donate, or reuse the seat.

For broader child restraint help, browse the car seat safety guides before choosing your next seat.

1. Find the car seat expiration label first

The expiration label is the fastest answer. Most car seats place it on the bottom, back, side, base, or plastic shell near the harness path.

Look for direct wording first. Common phrases include “expiration date,” “use by,” “do not use after,” “date of manufacture,” “DOM,” “model number,” and “serial number.”

The NHTSA used car seat safety checklist says a second-hand seat needs labels showing the date of manufacture and model number. Those details help confirm recalls and whether the seat is too old.

• Turn the seat over and inspect the bottom shell.
• Check the back panel near the top tether area.
• Look along both sides near the belt path.
• Lift removable padding and check the hard shell.
• Inspect the infant base as a separate part.
• Check the manual storage pocket.

Check hidden label locations

Some brands hide the serial label under fabric because the visible shell has limited flat space. That design protects the label from scratches, spills, and cleaning wear.

Lift only the removable cover sections the manual allows. Never remove harness parts or loosen structural components just to search for a label.

If the label looks faded, take a phone photo under bright light. Zooming in often reveals the printed month, year, model number, and useful-life wording.

2. Read the date of manufacture correctly

The date of manufacture tells you when the car seat was made. It is not the same as the purchase date, delivery date, or first-use date.

This difference matters because a seat can sit in a store, warehouse, closet, or garage before a child ever rides in it. The manufacturer still counts useful life from production.

Labels use several date formats. You can see “03/15/2020,” “2020-03-15,” “MAR 2020,” or a molded clock-style plastic stamp.

The key point is simple: a clear expiration date beats a calculated estimate. Use calculation only when the label shows manufacture date but no use-by date.

Date of manufacture vs purchase date

The purchase date feels logical because that is when the family starts using the seat. The manufacturer does not test the seat from your receipt date.

Plastic shell aging, harness wear, foam condition, labels, and model support all connect to the production date. That is why the date of manufacture sits beside the model number.

Keep the receipt for warranty or store return issues. Use the car seat label for expiration and recall checks.

3. Calculate the car seat expiration date

Use this formula when the seat shows a manufacture date but not a final expiration date: date of manufacture plus useful life equals expiration date.

For example, a seat made on March 15, 2020 with a 10-year useful life expires on March 15, 2030. A 7-year useful life would expire on March 15, 2027.

As of 2026, many child restraints fall in the 6-to-10-year range, but the exact number comes from the seat brand and model. Graco, Britax, Chicco, Evenflo, Safety 1st, and other makers set model-specific lifespans.

• Find the date of manufacture.
• Find the model name and model number.
• Open the instruction manual or brand support page.
• Search for “useful life” or “do not use after.”
• Add the lifespan to the manufacture date.
• Write the final date on your phone note.

Example: DOM 08/10/2019 plus 8 years means the car seat expires on 08/10/2027.

4. Check the car seat base, booster, and manual

Infant car seats often have two expiration checks: the carrier and the base. Check both because each part has its own label and safety role.

The carrier holds the child. The base anchors the carrier to the vehicle. A safe-looking carrier still needs a base within its useful-life period.

Booster seats also expire. A belt-positioning booster relies on shell shape, belt guides, labels, and structural integrity to position the vehicle seat belt correctly.

Transport Canada says parents should verify the date of manufacture and expiration date on the seat label or in the instruction manual, then follow the manufacturer instructions for that exact model. Read their child car seat expiry guidance for the official wording.

• Carrier label: check the shell and underside.
• Base label: check the bottom and connector area.
• Booster label: check the bottom and belt guides.
• Manual: check warnings and product lifespan pages.
• Registration card: check model and manufacture details.

5. What most people get wrong about car seat expiration dates

Most mistakes come from treating the seat like normal furniture. A car seat is a crash-tested child restraint, not just plastic, fabric, and foam.

The seat needs intact parts, clear labels, original instructions, no unsafe recall, and no crash history. Expiration is one part of that safety picture.

Wrong belief 1: “The seat expires after I buy it”

The useful-life clock starts at manufacture, not purchase. A clearance seat can already be one or two years old before a child uses it.

That does not make the seat unsafe on day one. It means you have fewer remaining years before replacement.

Wrong belief 2: “No visible cracks means safe”

Visible damage gives one warning sign. It does not prove the harness, foam, plastic shell, labels, or hidden stress points remain inside the tested use period.

Heat, cold, sunlight, cleaning chemicals, and repeated loading all add stress. The expiration date gives a clear cutoff before guesswork starts.

Wrong belief 3: “A used car seat saves money safely”

A used seat works only when its history is known. You need no moderate or severe crash, no missing parts, no recall problem, clear labels, and the instruction manual.

The American Academy of Pediatrics says not to use a seat that has been in a crash, recalled, too old, cracked, or missing parts. HealthyChildren also says to check the expiration date or use 6 years from manufacture when no expiration date appears in its car seat safety checkup.

6. Decide what to do if the date is missing

If the expiration date is missing, do not guess from the child’s age or family memory. Use the model number, manufacture date, manual, and manufacturer support.

Start with the label. Then search the brand support page using the model number. If the manual is missing, most major brands provide downloadable manuals.

• If you find the expiration date, follow that date.
• If you find only DOM, calculate from the manual.
• If the label is unreadable, contact the manufacturer.
• If the model number is missing, stop using the seat.
• If the seat has unknown crash history, replace it.
• If parts are missing, do not improvise replacements.

What most people do not think to ask is whether the manual belongs to the exact same model. A similar-looking seat can have a different lifespan, base, harness routing, or replacement part list.

Use the full model number. A single model family can include several versions across years.

7. What to do after you find an expired car seat

Stop using an expired car seat for child travel. The seat has passed the period the manufacturer supports for crash performance, parts, labels, and instructions.

Do not sell or donate an expired seat for reuse. Passing it to another family moves the same safety problem to another child.

• Remove the cover if local recycling rules require it.
• Cut the harness straps so nobody reuses them.
• Mark the shell “expired, do not use.”
• Check local recycling or trade-in programs.
• Buy a replacement by child height and weight.

Cleaning the cover before storage does not extend expiration. For safe fabric removal on compatible models, see how to remove a Graco car seat cover without disturbing the harness system.

Choose the next seat by fit, installation, child size, and vehicle compatibility. Expiration gives you the deadline; correct fit gives you daily protection.

Frequently Asked Questions

Where is the expiration date on a Graco car seat?

A Graco car seat usually shows the date of manufacture on a label and the useful-life wording in the manual or stamped shell text. Check the back, bottom, and hard plastic shell. Add the model’s useful life to the manufacture date when no direct expiration date appears.

Can I use a car seat after the expiration date?

No, you should not use a car seat after its expiration date for child travel. The seat has passed the manufacturer-supported use period. Replace it with a seat that matches your child’s height, weight, age stage, and vehicle installation needs.

Do car seat bases expire too?

Yes, infant car seat bases expire because the base is part of the child restraint system. Check the bottom of the base, connector storage area, and manual. A carrier within date still needs a base that is also within date.

What if my car seat has no expiration date?

If no expiration date appears, find the date of manufacture and model number. Then check the manual or contact the manufacturer for the useful-life period. If the label is missing or unreadable, stop using the seat because recall and age checks become unreliable.

Is a second-hand car seat safe if it is not expired?

A second-hand car seat is safe only when its full history is known. It needs clear labels, instructions, no missing parts, no unsafe recall, no cracks, and no moderate or severe crash history. If any answer is unknown, replace the seat.
