What is what channel is espn plus on directv?

ESPN+ is not a channel in the traditional sense on DIRECTV. It's a streaming service, separate from the DIRECTV channel lineup. You don't get ESPN+ simply by having DIRECTV; you need to subscribe to ESPN+ separately, either directly through the ESPN+ app or website, or potentially through a bundled package offered by DIRECTV. There is no specific channel number associated with it on the DIRECTV guide.
