A "Change of Address" refers to the process of updating your residential or mailing address with various organizations and services. This is important for ensuring that you receive mail, packages, and important communications at your new location. Common entities that require notification include the United States Postal Service, banks, utility companies, and subscription services. To officially change your address, you can typically fill out a form online or in person. It's advisable to notify these organizations as soon as you move to avoid any disruptions in service or missed correspondence. Additionally, consider informing friends and family of your new address.
