Car Seat Expiration & Manual Lookup
Safety 1st.
Safety 1st is applied to the seat record and Safety 1st owner center is linked. CalcSpan leaves expiration unknown until model or item number plus manufacture date and the current instructions are matched, with recall and crash checks kept separate.
Safety 1st profile
Safety 1st is applied to the seat record and Safety 1st owner center is linked. CalcSpan leaves expiration unknown until model or item number plus manufacture date and the current instructions are matched, with recall and crash checks kept separate.
- Safety 1st expiration and replacement instructions must be taken from the exact model label or manual.
- Safety 1st owner center is matched with model or item number plus manufacture date; the brand name alone cannot establish a model's service life or replacement instruction.
Use the Safety 1st route to match the exact restraint record, then enter only the printed expiration or the current manual's model-specific rule; recall, crash, damage and label status remain separate stop gates.
Official verification path
- Open Safety 1st owner center and match model or item number plus manufacture date.
- Copy the printed expiration date or the exact model manual's years-from-manufacture rule; keep source confirmation off until the identifiers match.
- Search NHTSA by car-seat brand and model, then stop for an open recall, crash instruction, damage, missing label, missing parts or an unreadable manufacture date.
NHTSA does not require one universal car-seat expiration period. CalcSpan uses only the exact maker label or the current model-specific manual, then applies crash, recall and condition gates. Review note: Finish the label, manual and recall checks.
Context matters.
- Replace a seat after a moderate or severe crash. Continued use after a minor crash requires every NHTSA minor-crash criterion and the manufacturer's instructions to allow it.
- Check NHTSA and the manufacturer for recalls using the exact model number and manufacture date; some recalls have a remedy rather than requiring disposal.
- Never infer suitability from age alone. Missing labels, unknown crash history, missing parts, damage or unavailable instructions can block safe second-hand use.

The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.
