What an Indiana notice means

Governed by Indiana Code art. 24-4.9. Businesses must notify affected consumers and the Attorney General's office, and the national credit bureaus too when more than 1,000 Indiana residents are notified.

Note: the count is Indiana residents only, not a total; the register prints a separate nationwide figure, which is not used as an Indiana count.
