Starting in 2005, the USPS offered customers the ability to design and purchase custom stamps, which were offered through third-party providers, like Stamps.com and Zazzle. The USPS prohibited certain types of images (such as alcohol, tobacco, gambling, weapons, controlled substances, political content, religious content, violent content, or sexual content) from being used on the custom stamps. The rules generated some controversy by uneven enforcement of the rules against the use of purportedly religious and political imagery. This eventually lead to two lawsuits, "Zukerman v. United States Postal Serv." and "Fletcher v. United States Postal Serv." On June 9, 2020 the District of Columbia Circuit ruled in "Zukerman v. United States Postal Serv." that the content rules didn't meet the "objective, workable standards" test established in "Minnesota Voters Alliance v. Mansky". One week later, the USPS discontinued the custom stamp program.
