Toll-free numbers (800, 888, 877, 866, 855, 844, 833) are free to call and used by businesses and government — but they are also heavily spoofed by robocallers, and outbound telemarketing from toll-free numbers is common. Carrier assignment shows who the prefix was allocated to; numbers can be ported, and caller ID can be spoofed.
