Is USDC ERC-20?

I'm quite interested in the USDC cryptocurrency, but I'm a bit confused about its technical details. Could you clarify for me if USDC is indeed an ERC-20 token? ERC-20, as I understand, is a technical standard used for smart contracts on the Ethereum blockchain, and it's essential for ensuring compatibility and interoperability among various tokens. So, is USDC built on this standard, or does it operate on a different mechanism? I'd appreciate it if you could break it down for me in a way that's easy to understand.
