Understanding USPS Mail Restrictions: Domestic and International Guidelines

Mail is the cornerstone of communication, particularly in the United States where the United States Postal Service (USPS) is one of the world's largest postal networks. To ensure the safety, security, and efficiency of mail delivery, the USPS has established a comprehensive set of rules and regulations outlined in the Domestic Mail Manual and the International Mail Manual. These manuals cover all aspects of mailing, from weights and sizes to acceptable content, ensuring that both senders and recipients understand the rules and requirements.
