On Tuesday the House of Representatives voted to repeal an Obama-era law that demanded ISPs have permission to share personal information - including location data.
Supporters of the move said it would increase competition, but critics said it would have a “chilling effect” on online privacy.
President Donald Trump is expected to sign the order soon.
The repeal was strongly backed by major providers such as Verizon, AT&T and Comcast, who argued that ISPs were being subject to stricter privacy laws than companies like Google or Facebook.
