Bank routing numbers, or “routing transfer numbers” (RTN’s) appear on virtually all of our checks and other demand instruments, but as common as they are most of us have no idea what their purpose is.
Occasionally we’re asked to provide our bank’s routing number—such as for direct deposit of income tax refunds—but this does little to clear up the mystery behind them or why they’re so important.
Think of it this way: each of us has a checking account number—the bank has its own identification number, and that’s the bank routing number. That number is at least as important to the bank as our checking account numbers are to us.
