How to Find the Expiration Date on a Car Seat

To find the expiration date on a car seat, check the white manufacturer label, the plastic shell, the bottom of the seat, the back panel, the infant base, and the instruction manual. Look for “Do not use after,” “Date of Manufacture,” “DOM,” model number, serial number, or useful life wording.

Car seat labels can feel confusing when your child needs a safe ride now. Some seats show a clear expiration date, while others show only a manufacture date.

The common mistake is checking the purchase receipt. A car seat usually expires from its manufacture date, not the day you bought it. This takes about 8 minutes to read.

Start with the label, then confirm the same details in the manual. That gives you the safest answer for your exact seat.

1. Check the Car Seat Label First

The car seat label is the best place to start because it identifies the exact model, manufacture date, and safety information. Most brands place this label on the back, bottom, side, or underside of the child restraint.

Look for a white or silver sticker with printed details. The label can include the model number, serial number, Date of Manufacture, and expiration wording.

• Check the back of the car seat shell.
• Turn the seat over and check the bottom.
• Look along both side panels.
• Check near the harness path.
• Check behind removable fabric pads.
• Inspect the infant base separately.

The label matters because it connects your seat to one exact manual, recall record, and useful-life rule.

2. Read “Do Not Use After” Wording

Some car seats print the expiration date directly on the label or plastic shell. This is the clearest version because no calculation is needed.

The wording can appear as “Do not use after,” “Expires on,” “Expiration date,” or “Useful life ends.” Follow that date exactly.

You might expect every brand to use the same label format. They do not. One seat can show a full expiration date, while another seat from the same brand can show only the Date of Manufacture.

Label wording	What it means	What to do
Do not use after	Final safe-use date	Stop using after this date
Date of Manufacture	Date the seat was made	Add the listed useful life
DOM	Short form for manufacture date	Check manual for lifespan
Model number	Exact seat version	Use for manual and recall checks

The safest shortcut is simple: direct expiration wording beats general brand averages.

3. Use the Manufacture Date When No Expiration Date Appears

If no expiration date appears, find the Date of Manufacture and add the useful life from the manual. This gives the car seat expiration date for that exact model.

For example, a seat made on March 15, 2021 with a 7-year useful life expires on March 15, 2028. A seat made on June 1, 2020 with a 10-year useful life expires on June 1, 2030.

Graco explains this formula as Date of Manufacture plus useful life equals the car seat expiration date. You can compare your label with the official Graco car seat expiration guide.

1. Find the Date of Manufacture.
2. Find the useful life in the manual.
3. Add the useful life to the manufacture date.
4. Write the final expiration date down.
5. Check the base separately.

For a deeper explanation of the date calculation, read how long a car seat is good after manufacture date.

4. Check the Car Seat Base Separately

An infant car seat base can have its own expiration information. Check the base label even when the carrier label looks safe.

This matters because the carrier and base are separate crash-management parts. The base holds the carrier to the vehicle seat during travel.

A newer infant carrier should not be clicked into an expired, damaged, incompatible, or recalled base. Match the model numbers exactly.

5. Use the Manual When the Label Is Faded

The car seat manual gives the useful life, approved parts, cleaning rules, fit limits, and contact details. Use the manual when the label shows only partial information.

If the paper manual is missing, search the manufacturer website with the model number and manufacture date range. Many brands host older manuals online.

Transport Canada says parents should verify the manufacture date and expiry date using the seat label or instruction manual. Their child car seat expiry date guidance also advises contacting the manufacturer for model-specific details.

If the label is unreadable and the manufacturer cannot confirm the date, stop using the seat. Guessing from seat appearance creates a real safety gap.

6. Know Where Each Brand Hides the Date

Different brands place expiration details in different spots. Search all common label areas before deciding the date is missing.

Safety 1st says some expiration dates are printed on the bottom of the car seat itself. Graco seats often show a Date of Manufacture label, then require checking the manual or shell stamp for useful life.

• Graco: check DOM label and shell wording.
• Safety 1st: check bottom and printed shell date.
• Chicco: check back, base, and manual.
• Britax: check label near the shell or base.
• Evenflo: check sticker, manual, and molded date.
• Maxi-Cosi: check carrier, base, and side labels.

Use brand guidance only after confirming your exact model. Product families change label locations across model years.

7. Understand Why Car Seats Expire

Car seats expire because manufacturers set a defined useful life for the seat’s tested materials and safety design. That useful life covers the shell, foam, harness, buckles, labels, and installation parts.

A car seat works as a crash restraint, not a simple chair. During a crash, the seat must hold the child, manage force, keep the harness placed correctly, and stay attached to the vehicle.

Heat, cold, sunlight, food spills, harsh cleaners, repeated installation, missing parts, and older safety standards all reduce confidence in an aging seat. That is why the expiration date matters even when the seat looks clean.

NHTSA’s car seat and booster seat safety guide explains that children should use the correct car seat type for their age, height, and weight.

8. Avoid Common Expiration Date Mistakes

Most mistakes happen because parents check the wrong date or only check one part. The purchase date, gift date, and first-use date do not replace the manufacturer’s date.

A used car seat needs extra caution. You need the expiration date, model number, manual, recall status, original parts, and full crash history.

• Do not use the purchase date as the start date.
• Do not ignore the infant base label.
• Do not trust a faded label without confirmation.
• Do not use a seat after any unknown crash.
• Do not buy a used seat without full history.
• Do not assume all brands last 10 years.

What most people do not think to ask is whether the seat was stored before sale. A new-looking clearance seat can already have one or two years gone from its useful life.

9. Decide What to Do If the Seat Is Expired

If the car seat is expired, stop using it and replace it before the next ride. Do not sell, donate, or pass it to another family.

Before disposal, remove the fabric cover, cut the harness straps, mark the shell as expired, and check local recycling rules. Some retailers also run car seat trade-in events.

If your child has outgrown the old seat, the next step is choosing the right stage. For age and fit guidance, see when a child can face forward in a car seat.

10. Run a Final Five-Minute Safety Check

Before using or reusing any car seat, check expiration, recalls, crash history, parts, fit limits, and installation instructions. Expiration is only one safety checkpoint.

Use the model number and serial number to check recalls. Registering the seat also helps the manufacturer contact you about safety fixes.

1. Find the expiration date or DOM.
2. Confirm the useful life in the manual.
3. Check the carrier and base.
4. Confirm no crash history.
5. Check for recalls.
6. Inspect harness and buckle parts.
7. Confirm your child still fits the limits.

If the seat is for a baby, inserts and harness fit matter too. Read when to take the infant insert out of a car seat before changing padding.

Frequently Asked Questions

Where is the expiration date on a car seat?

The expiration date is usually on the back, bottom, side, plastic shell, or manufacturer label. Some seats print “Do not use after” directly on the shell. Infant car seat bases can have separate labels, so check the base too.

What does DOM mean on a car seat?

DOM means Date of Manufacture. It tells you when the car seat was made, not when you bought it. If no expiration date appears, add the model’s useful life to the DOM.

Can I use a car seat if I cannot find the expiration date?

Do not guess if the expiration date is missing. Find the model number, serial number, and manufacture date, then contact the manufacturer. If the manufacturer cannot confirm the safe-use date, replace the seat.

Do car seat bases expire too?

Yes, car seat bases expire too. The base can have its own label, model number, and useful-life rule. Always check the carrier and base separately before using an infant car seat system.

Is the car seat expiration date based on purchase date?

No, car seat expiration is usually based on the manufacture date. The purchase date can be later than the manufacture date, especially for older store inventory. Always follow the label and manual for the exact model.
