SSN was originally used to track individual's tax payment, but now its use has been expanded to include distinguishing individual's identity, similar to the function of "resident ID number" in China. The social security number is generally written in the form of "3 digits -2 digits -4 digits" like 450- 12-3672.
The name of Anka, an extended information organization, must be the same as the real (official) name of other legal documents, and the English spelling must be exactly the same. If there is a space in the middle of your official name, then the name on the social security card should also have a space. Put it together, you have to put it together. If there is no small horizontal "one" in the middle of the name, there should be no small horizontal on the social security card.
If the staff of the Social Security Bureau misspells even one letter of their name, they should also ask the Social Security Bureau to change it in time. If it is officially renamed due to marriage, divorce, judge's ruling or other reasons, it should be replaced at the Social Security Bureau in time. When applying for change, you should bring the relevant original to prove the name change.
