Does Coinbase require identity verification?

Could you please clarify for me if Coinbase mandates identity verification as a prerequisite for using its services? I'm interested in exploring the crypto world but I'm also concerned about the security measures required. Would I need to provide personal details or go through any verification process before I can start trading on Coinbase? It would be helpful to know the specific steps involved in this process, if any, to ensure a smooth and secure experience.
