The expiration date on a car seat is most commonly found on a sticker on the back or bottom of the seat, or molded directly into the plastic shell, typically showing either the expiration date or the date of manufacture (DOM) from which you calculate expiration. For infant car seats, check both the carrier and the base separately, as both components have the same expiration date but may display the information in different locations.
Finding your car seat's expiration date is crucial for ensuring your child's safety. According to the National Highway Traffic Safety Administration (NHTSA), manufacturers use expiration dates to indicate the expected useful life of their products[1].
Car seat expiration dates aren't arbitrary numbers. They represent the manufacturer's confidence in the product's structural integrity and safety performance over time. Autvex safety experts emphasize that using an expired car seat is like ignoring warning indicators in your vehicle—both compromise safety.
The most common location for expiration dates is on a white or gray sticker attached to the plastic shell[2]. Turn your car seat around and check the back, bottom, or sides for manufacturer labels.
Look for these specific areas:
The sticker typically contains multiple pieces of information including the model number, serial number, date of manufacture, and either the expiration date or the seat's lifespan in years.
The serial number and DOM are essential for determining expiration when it's not explicitly printed[3]. These identifiers also help with recall checks and warranty claims.
| Information Type | Common Location | Format Example |
|---|---|---|
| Serial Number | Bottom of seat | SN: 123456789 |
| Date of Manufacture | Back sticker | DOM: 03/15/2020 |
| Model Number | Side label | Model: 1234567 |
| Expiration | Bottom/back | EXP: 03/15/2027 |
If only the DOM is visible, add the manufacturer's stated lifespan (typically 6-10 years) to calculate the expiration date.
Your car seat's manual contains critical expiration information when the physical seat doesn't clearly display it. Keep the manual stored with your important documents as it's your primary reference for safety information[3].
The manual typically includes:
Many manufacturers now offer digital manuals online, searchable by model number. This proves helpful when buying used items that may lack original documentation.
Manufacturers use various methods to display expiration information, and understanding these different formats helps ensure accurate interpretation of safety dates.
Date of manufacture stickers follow standard formats but vary by brand[2]. Understanding these formats prevents misinterpretation of critical safety information.
Common date formats include:
Some manufacturers use codes requiring the manual for interpretation. When uncertain, contact the manufacturer directly with your serial number for clarification.
When only the DOM appears, you must know the manufacturer's specified lifespan to determine expiration[4]. This calculation becomes your responsibility as the caregiver.
Standard lifespans by seat type:
For example, a seat manufactured on 03/15/2020 with a 7-year lifespan expires on 03/15/2027. Mark this date in your calendar immediately.
Graco places expiration information on the bottom or back of their seats, requiring calculation from the DOM[4]. Graco doesn't print explicit expiration dates but provides clear lifespan guidelines.
Graco expiration periods:
To find your Graco seat's information:
Autvex recommends photographing these labels immediately after purchase for easy reference, similar to documenting vehicle specifications.
Parents often overlook that car seat bases have their own expiration considerations, particularly important for families using multiple bases or sharing between vehicles.
Car seat bases expire on the same date as their corresponding carrier[5]. The expiration information typically appears on the base's underside or along the belt path area.
Check these specific base locations:
Many parents purchase extra bases for multiple vehicles. Each base should be checked individually, as manufacture dates may differ even within the same purchase.
The carrier and base share the same expiration date when sold as a system[5]. However, separately purchased bases may have different manufacture dates.
Important considerations:
Document both dates when using separate pieces, especially if acquired at different times or from different sources.
Inspect both the carrier and base during every installation to ensure neither has exceeded its useful life[1]. This dual-check system prevents overlooking critical expiration dates.
Safety check protocol:
This vigilance mirrors the attention needed when inspecting vehicles for safety compliance.
Understanding the science behind expiration dates helps parents appreciate their importance beyond mere manufacturer recommendations. These dates reflect genuine safety concerns backed by extensive testing.
Plastic and fabric components deteriorate over time through molecular breakdown[6]. This degradation isn't always visible but significantly impacts crash performance.
Degradation factors include:
Cars experience temperature swings from -20°F to 140°F throughout the year. These extremes accelerate material aging beyond what indoor products experience.
NHTSA updates safety standards regularly, with major changes coming in 2025-2026[1]. New regulations require enhanced side-impact protection that older seats cannot meet.
Recent safety improvements include:
Using an expired seat means missing these critical safety advances. It's similar to how modern vehicles offer superior protection compared to older models.
Car seats are single-use safety devices after crashes, even minor ones[6]. Expiration dates help prevent circulation of potentially compromised seats.
Hidden damage risks:
Without knowing a seat's complete history, expiration dates provide a definitive cutoff for safe use, protecting children from seats with unknown damage.
The secondhand market presents unique challenges for car seat safety. While budget-conscious parents may consider used options, proper verification becomes critical.
Used car seats are only safe when you know their complete history[7]. NHTSA recommends extreme caution with secondhand seats due to unknown factors.
Essential verification checklist:
Many experts recommend buying new when possible, as the cost difference is minimal compared to potential risks. Consider this like choosing [safety equipment]—reliability matters most.
Most manufacturers require immediate replacement after any crash[7]. The forces involved in collisions can cause structural damage invisible to visual inspection.
Crash damage concerns:
Insurance typically covers car seat replacement after accidents. Document the seat's involvement for claims, similar to vehicle damage claims.
Online verification is limited to lifespan information, not specific dates[2]. Physical inspection remains necessary for actual DOM or expiration dates.
Online resources provide:
Always cross-reference online information with physical labels, as manufacturing runs may vary in specifications or components.
Proper disposal of expired car seats prevents their dangerous reuse while supporting environmental sustainability. Multiple options exist for responsible seat retirement.
Expired car seats must be rendered unusable before disposal to prevent unknowing reuse[8]. This destruction seems wasteful but protects children from compromised safety equipment.
Proper disposal steps:
Some communities offer special collection events for car seats, similar to hazardous waste disposal days.
Major retailers offer periodic trade-in programs providing discounts on new seats[8]. Target's program runs twice yearly, accepting any car seat regardless of condition.
Current trade-in programs:
| Retailer | Frequency | Discount | Accepted Items |
