Tell HN: Car dealership scanned my license and extracted my birthday to wish me
I gave a nickname but they wished me happy birthday with my real name. I’m pissed.
They probably used an online service that has your mailing address and birthday on file: https://www.valpak.com/advertise/postcards-service/birthday-...
Depending on your activities/state that could have even been information scraped from a public database like USPS mail forwarding or voter registration.
