No, the cash value loaded onto a Clipper card (the Bay Area's all-in-one transit card) never expires. Whether you have a physical plastic card or a digital version in your Apple or Google Wallet, the "cash value" stays on the account indefinitely. However, with the transition to "Clipper 2.0" in late 2025 and early 2026, some older, unregistered cards may require a one-time "migration" at a physical kiosk or via the mobile app to ensure the balance is recognized by the new, upgraded fare gates. It is important to distinguish between "cash value" and "transit passes." While the money you load is permanent, specific monthly or weekly passes (like a BART High Value Discount or a Muni Monthly Pass) do have fixed expiration dates based on the period for which they were purchased. If your physical card is lost or damaged, you can transfer your unexpired balance to a new card only if the original card was registered to a Clipper account.
