Can you verify a bank routing number?

Excuse me, but I was wondering if you could possibly clarify something for me regarding bank routing numbers. I understand that these numbers are used to identify financial institutions when processing transactions, but I'm curious if there's a way to verify their authenticity or accuracy. Is there a specific process or tool that you use to validate bank routing numbers, or do you rely on other means to ensure that the information you're working with is correct? I'd appreciate any insight you can offer on this matter.
