How to deal with social security in different parts of the United States?

One is sealed and the other is transferred.

You can send the previous social security and move to a new place.

The social security card in the United States is simply printed as a paper card, and the core is a set of 9 digits, but the behind of this set of numbers is not simple. It hides a huge computer information system, a huge database that records almost all Americans' social security payment and collection records, wages, work and family changes. The parties only need to say the social security card number, they can enter this information system and database, pay and receive social security in any state in the United States and designated cities in most countries in the world, and truly realize the "national communication" or even "global communication" of social security. Not only that, the social security number in the United States also has an "overflow" effect. Because of its long-term stability and lifelong tracking and recording of the parties' credit records, it has become an information source that banks and trusts, police, border inspection, demography, and even education and electoral institutions rely on. In the history of social security development in the world, the United States is the first federal country to promote social security numbers and social security cards within a country, and it is a quite successful model. A wise man corrects his own mistakes through the mistakes of others. China's social security construction is at a critical stage, and relevant departments are vigorously promoting the application of social security cards with unified standards and compatible functions nationwide, hoping to realize the "one card" as soon as possible. American social security number and social security card have the advantages of early overall planning, wide application and high reputation. What enlightenment can they bring us?
