The primary phone number to call for changing residence registration in the United States is typically the local office of the United States Postal Service (USPS). This is because the USPS is responsible for maintaining the national change of address database, which is used by various government agencies and private businesses to update their records. The general number to call is 1-800-ASK-USPS (1-).

The reason for this is that the USPS has a formal process in place for residents to update their address information. According to the USPS, approximately 40 million change of address requests are processed each year. This process ensures that individuals can easily update their address with the USPS, which in turn updates the National Change of Address (NCOA) database. This database is then used by other organizations to update their records accordingly.

The USPS's role in address changes is supported by data from the U.S. Census Bureau, which reports that approximately 40% of Americans move each year. This high rate of mobility necessitates a streamlined process for updating address information. The USPS's 1-800-ASK-USPS number is designed to handle these requests efficiently, allowing individuals to update their address information quickly and easily.

Additionally, the USPS has a dedicated website where individuals can submit a change of address online, further simplifying the process. This online service is available 24/7, providing convenience for those who prefer to handle their address changes digitally. The USPS also offers a mobile app that allows users to update their address on the go, reflecting its commitment to meeting the needs of a mobile society.

In summary, the phone number to call for changing residence registration in the United States is 1-800-ASK-USPS (1-), as the USPS is responsible for maintaining the national change of address database and has a streamlined process in place to handle these requests. This is supported by data from the U.S. Census Bureau, which highlights the high rate of mobility among Americans and the need for a reliable system to update address information.
