Buying or accepting a used car seat

A seat handed over at a family gathering or bought from a listing arrives without its paperwork. NHTSA publishes a checklist for exactly this situation, and it is short — five statements you either can or cannot tick off. NHTSA's used car seat safety checklist frames it this way: if you are considering a second-hand seat and you can check off each statement, the seat "may be okay to use". Note the conditional. NHTSA does not clear an individual seat, and neither does this page — the two of them are a way of finding out what you actually know about the object in front of you.

1. You know its history, and it has never been in a crash

NHTSA's first item is that the seat has never been involved in a moderate to severe crash. That is a fact about the seat's past, which means it is really a question about the person handing it over: can they tell you, and would they know? A seat from a sibling's car is a different proposition from a listing with no name attached.

Graco's published position goes further than NHTSA's, and it is worth reading as the manufacturer's own view rather than ours:

Unless you know the complete history of a seat and that it’s never been involved in even the most minor of crashes, it’s safest to purchase a new car seat. That way, you’re assured of up-to-date car seat technology and a clean history.

Drew Kitchens, Graco Global Engineering Director of Car Seats, quoted on Graco's own car seat expiration page, checked 2026-08-27. Graco's answer to "Can I purchase a used car seat?" is that it is not a good idea. That is Graco's position, stated in Graco's words.

2. The labels are there — date of manufacture and model number

NHTSA's second item asks for labels stating the date of manufacture and the model number, and gives the reason: you need that information to find out whether there is a recall on the seat, or whether the seat is too old. Both of those checks fail at the first step if the label is missing, unreadable, or has been peeled off.

Federal law requires the month and year of manufacture on the label. Expiration is the manufacturer’s own policy, not a federal rule. So the label is doing double duty here — it is the one thing the law puts on the shell, and it is the input to every other item on this list. Where the label sits on infant seats, convertibles, and boosters.

3. It is not past the maker's stated useful life

"Too old" is NHTSA's phrasing, and the figure behind it belongs to the manufacturer, not to a regulation. Take the date of manufacture from the label and check it against what that maker states for that kind of seat. The stated figures on the makers' own pages run from 6 to 12 years, and several makers state more than one figure depending on the seat, so the maker's own wording matters more than any general rule of thumb.

Every maker's stated figure, quoted with its source, or the side-by-side table on how long car seats last.

4. The recall record — look it up, do not take anyone's word

NHTSA's fourth item is about recalls, and the only honest way to tick it is to run the lookup yourself. A seller's assurance is not a record, and neither is a page like this one: we do not hold a recall status for your seat, and we will never tell you a seat is clear. What we can tell you is where the record lives.

Search the seat in NHTSA's recall database using the model number and date of manufacture off the label. If something does come back, NHTSA's guidance is to contact the manufacturer — some problems can be fixed, and a remedy may be free. Registering the seat with its maker afterwards is what keeps you on the list for anything issued later; the maker's registration link is on its brand page.

5. It has all its parts, and it has its manual

The last two items are one idea: a seat is the whole assembly plus the book that describes it. NHTSA says a missing part can often be ordered from the manufacturer, and that you can order the instruction manual from them too. The manual is worth chasing for a second reason on this site's terms — for most makers it is where the "Do not use this child restraint after…" statement lives, which is the figure item 3 turns on.
