UUIDs for US Census Tracts Groups for OD Analysis

I'm hoping to use Census Tracts for an Origin-Destination Analysis, but I couldn't find any documentation for how to define these zones. On the Insight Platform, a 'Zone Name' with an 11 digit number for the Census tract code - these seem to correspond with the Census tract codes from the US Census Bureau.

Are these codes the correct way to define the UUIDs for the origin-destination analysis?
