Why YSK: If you are a US Resident, don’t lose your Social Security card more than 10 times, or else you might need to respawn 💀
Excerpt from Wikipedia:
In accordance with §7213 of the 9/11 Commission Implementation Act of 2004 and 20 CFR 422.103, the number of replacement Social Security cards per person is generally limited to three per calendar year and ten in a lifetime.
Not true - there are whole ranges that specifically aren’t in use (mostly specific values for the first three digits that are intentionally not used). Outside those ranges though, yeah, basically any 9 digit number. Add one to the last digit of your SSN and if you were born before 2014 you likely get someone born in the same hospital on the same day.
