The DCSID is a unique identifier that associates the data collected from a website or app with a space or profile in Analytics 10.

A DCSID is generated when you create a space in Analytics 10, when you create an SDC data source in Analytics 9, or as an option when you create a profile in Analytics 9.

To view the DCSID on the Space Details page for an existing space, on the Spaces dashboard, click the space and then click on the upper right corner of the page.
