Yes. Frozen at 0°F (−18°C), peanuts keep best quality for 24 months. Frozen food stays safe indefinitely; the time is for taste and texture.

How can I tell if peanuts have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
