Its like a token that is generated and may support more privacy (as its not driver license or Ssn getting leaked) while giving us equal benefit of how reproducibility.

Hoping cost of maintaining token can be decreased/balanced with tremendous inefficiencies that happen because of lack of it.

There may improved efficiencies even if we reach a hybrid period whereby CA identity is added to matching options for national systems.

…which might push others into joining when they see the advantages we are able to realize.

+1 to Nate

We struggle to get registration staff to ask and document a preferred language correctly.

Same goes for race/ethnicity.

Perhaps a naïve question...What is the balance of value-add vs burden-add to using current plus those variable elements of historical data that a system has previously recorded (previous addresses, phone numbers, etc) given that presumably the more elements that are matched increases the matching accuracy? Or in general including as many variables in the algorithm as available.

MRN helps when you're looking to connect with that institution for further follow-up. But that's about it. Not as an identity matching data point.

We have certainly found CIN to be a benefit, more so than MRN. But I'm just echoing Belinda ;)
