Where to find the date on a Britax seat

Look for a white sticker on the plastic shell, usually on the back, the side or underneath. It lists the model number and the date of manufacture, and newer seats often print the expiration date on the same label or stamp it into the plastic.

When to replace a seat before it expires

  • After a moderate or severe crash. NHTSA lists the conditions under which a seat can stay in use after a minor one: car seat use after a crash.
  • When the label with the date of manufacture is missing and the maker cannot tell you the date from the serial number.
  • When the seat has a recall that has not been fixed. Register the seat with its maker so recall notices reach you.
  • When your child is past the seat's height or weight limit, whatever the date.

Before you throw an expired seat out, cut the harness straps and write EXPIRED on the shell so nobody picks it up and uses it.
