Most financial institutions impose daily, weekly, or monthly limits on mobile check deposits to manage risk. Checks that exceed your specific bank's predefined mobile deposit threshold typically cannot be processed through the app and must be deposited in person at a branch. Before attempting to deposit a large check, you should log into your mobile banking app or check your bank's website to review your specific account's deposit limits. If your check amount is higher than the permitted daily mobile limit, visiting a branch is the most reliable and secure way to ensure the funds are processed correctly without being automatically rejected by the bank’s security algorithms.
