I have a Social Security Number through my Ojibway Indian Status. I moved from Canada and worked here for a period of about 12 years and obtained a permanent resident card. I moved back to Canada for 10 years and now have returned to Florida to work for the winter months. Is my SSN good to go or will I run into any issues?
US social security numbers are permanent.
Q20: Are Social Security numbers reused after a person dies?
A: No. We do not reassign a Social Security number (SSN) after the number holder's death. Even though we have issued over 453 million SSNs so far, and we assign about 5 and one-half million new numbers a year, the current numbering system will provide us with enough new numbers for several generations into the future with no changes in the numbering system.
While this does not absolutely prove I am right, it indicates that SSNs are assigned to a person and never reassigned, therefore your number will be reused when you re-immigrate to the US.
