Amidst the rapid online marketplace growth during the pandemic in 2020, the state of Arkansas passed a bill that enforced e-commerce marketplaces like IG+FB Shops to verify and disclose seller information for consumer protection. In 2021, the state of Ohio followed with a similar bill, and the US Congress was preparing to pass a similar law at the federal level. To help 10M+ sellers in the US to comply with the law, I worked directly with a legal counsel to design and ship the seller verification flow. The flow successfully launched in two milestones—Arkansas INFORM Act SB470 and the Federal INFORM Consumers Act. The flow also anticipated the upcoming EU regulation, which is scheduled to launch by 2024.
