Amazon and other online-only retailers are trying to thwart federal and state legislation that would require businesses to disclose contact information for third-party sellers.

The bill forces Amazon and other online retailers to verify the identity of third-party sellers and provide consumers with a way to contact their stores. The proposed bill is competing retailers in stores, including Home Depot, Walgreens, and JC Penny, who support the bill, against online retailers such as Amazon, Etsy, eBay, Poshmark and others.

The invoices come as traditional retailers lost ground to online retailers during the pandemic: In 2020, 20 percent of consumers’ retail purchases were made online, up from about 14 percent in 2019. But the legislation is also being proposed in response to a large number of counterfeit, stolen and dangerous items that have appeared on market sites .

Online retailers argue that the bills would compromise the privacy of third-party sellers. On some platforms, most merchants run their businesses from their homes. Etsy, for example, says that 97 percent of its sellers do. In an Amazon seller survey, it was found that 70 percent work outside of their Amazon businesses, suggesting that they, too, run the business from home.
