The purpose of this legislation, known as the Postal Service Transparency and Review Act, is to enhance oversight of significant changes to postal services in the United States. It aims to ensure that any major alterations to how postal services operate are thoroughly reviewed and considered before they are implemented. Key provisions of the Act require the United States Postal Service (USPS) to submit any proposed significant changes to postal services to the Postal Regulatory Commission at least 180 days before those changes take effect.
