Are applications for credit with ITINs riskier than applications with SSNs?

The CFPB and DOJ issued a joint statement last year reminding FIs that "unnecessary or overbroad reliance on immigration status" in creditworthiness assessments "may run afoul of the law." Since then, the risk associated with ITINs on credit applications has been a hot topic.

To shed some light on this, we did an analysis on the 12-month performance of 1.26 million anonymized card and auto tradelines. We found that the credit performance of ITIN holders was not riskier than SSN holders, even when controlled for credit score. In cards, ITINs actually appear to be less risky than SSNs.

For example, the DQ rate at 12 months for cardholders in the 600-700 VantageScore band was 5.97% for consumers that applied with SSNs, but 4.29% for consumers that applied with ITINs.

Twice a year, our finance team freaks out because our G&A expenses have doubled month over month.  Fortunately, it’s only because we run “SentiWeeks”, where we fly the entire company somewhere to meet up and have fun together (and then G&A goes back to normal the next month). It's quite expensive, so why do we do it?

SentiLink is a distributed team--we've got offices in SF, Austin, NYC, Chicago, LA, Denver, Bellevue, and the East Bay, plus a lot of folks working remotely. This approach allows us to hire amazing people no matter where they are. But not having everyone collocated does have real downsides: it's harder to build culture, harder to communicate, and harder to form strong relationships.

SentiWeek is one of the ways we try to offset that. We work together, have fun together, and collaborate together for a week. (And we also always find out who's a lot taller than they look on Zoom).

It's only twice a year, but we've found that having these shared experiences starts friendships, improves alignment, and frankly gets everyone fired up.

And when we return to Zoom the next week, everyone knows they're not talking to a screen but rather to a real person.
