How long does a bitcoin wallet address last?

Could you elaborate on the lifespan of a Bitcoin wallet address? I've heard they're permanent, but I'm curious if there are any exceptions or scenarios where an address might become invalid. For instance, does the address expire if it hasn't been used for a long time? Or does it depend on the wallet provider or platform? It would be greatly appreciated if you could clarify the permanence and any potential limitations associated with Bitcoin wallet addresses.
