A football helmet has two dates inside it. The manufacture date and the recertification date. Both matter, and parents who have never looked rarely know which their kid is wearing.

The NOCSAE certification window. A helmet is NOCSAE-certified at manufacture. After that, it must be reconditioned and recertified by an NAERA-licensed reconditioner, typically every one to two years, depending on the league. The recondition involves stripping the helmet, replacing padding, repainting, and re-testing.

A helmet can be recertified up to 10 years after the manufacture date. After 10 years, no reconditioner will recertify it. The helmet is retired.

Where to find the dates. Pull the helmet liner. Inside the shell or on the inside crown, there are two stickers. The first reads “Manufacture Date” with a month and year. The second reads “Reconditioned” or “Recertified” with a month, year, and the name of the NAERA-licensed reconditioner.

If you cannot find a recondition sticker, the helmet has either never been reconditioned (problem if it is more than two years old) or someone removed the sticker (problem regardless).

What gets a helmet failed at recondition. Cracks in the shell, even small ones. Compressed padding that does not return to shape. Stripped or missing hardware. A face mask that has been bent or replaced with a non-matching one. Modifications to the shell, including drilled holes, painted-over decals, or stickers that obscure certification markings.

Helmets that fail recondition cannot be returned to play. They are destroyed.

The league’s role. Programs that take helmet certification seriously have a yearly recondition cycle, contract with an NAERA-licensed reconditioner, and check helmets at the start of each season. Programs that do not are programs that hand out helmets with whatever stickers are inside.

Lacrosse, baseball, and softball helmets. NOCSAE certifies lacrosse and batting helmets too. Recertification cycles are different by sport and by manufacturer. The same principle applies: look inside, find the dates, replace if you cannot verify.

What to ask your league.

“Are all team-issued helmets reconditioned and recertified annually by an NAERA-licensed reconditioner?” The answer should be yes.

“Are helmets older than 10 years from manufacture removed from circulation?” The answer should be yes.

“How do you handle helmets that take an impact during a game or practice?” The answer should be that the helmet is inspected and, if the impact was significant, sent for reconditioning before being reissued.

Replacement timing for the family-owned helmet. If you bought the helmet new and the kid wears it through one or two seasons of youth football, you have time. Track the manufacture date. Send it to a reconditioner once a year through one of the licensed shops. Replace the helmet outright at the 10-year mark, or earlier if it shows shell cracks or padding compression that does not recover.

The cost of a new youth football helmet is real. The cost of a 12-year-old helmet protecting a kid against a head impact is much higher.
