US state-by-state data breach notification requirements: how many days a business has to notify affected residents after discovering a breach, the deadline and resident-count threshold for notifying the state Attorney General (or equivalent regulator), and the resident-count threshold that triggers notice to consumer reporting agencies. Answers 'how many days to notify after data breach', 'data breach notification deadline [state]', 'when must a company notify the attorney general of a data breach', 'what is the breach notification law in [state]', 'how long does a company have to report a data breach to customers', 'data breach notification requirements by state'. Hard deadlines range from 30 days (California, Florida, Washington) through 45 days (Oregon, Wisconsin) to 60 days (Texas); most states require 'most expedient time possible and without unreasonable delay' with no hard number. No single government page states all 50 states together — each state's statute is the authority — which is why aggregator surveys (Foley, IAPP, Perkins Coie) exist but cite the statutes we read directly. Each record covers one state and its primary breach notification statute.

## Provenance — what every record carries

Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.

## Licence position

State statutes are edicts of government and are not subject to copyright under 17 U.S.C. § 105 (for federal government works) and the equivalent edict-of-government doctrine applied by courts to state legislative materials (Building Officials v. Code Technology, 628 F.2d 730 (1st Cir. 1980); Georgia v. Public.Resource.Org, 590 U.S. 255 (2020)). Short verbatim quotes taken from each statute, attributed to the state and statute citation, for the purpose of stating a fact about the law. No compilation is reproduced wholesale. Facts are not copyrightable (Feist, 1991).

Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.
