Is USDT BEP20 the same as USDT BSC?

Could you clarify for me if USDT BEP20 is indeed identical to USDT BSC? I've been hearing about both of these tokens in the cryptocurrency sphere and while I understand they are both stablecoins pegged to the US dollar, I'm not sure if they represent the same asset or if there are any differences in their functionality, compatibility, or even their underlying blockchain technology. Would you mind explaining the nuances between the two, if any, and whether they can be used interchangeably in transactions? Thank you for your assistance in clarifying this matter.
