On June 25, 2011, the Social Security Administration changed the SSN assignment process to “SSN randomization”,[36] which did the following:

The Social Security Administration does not reuse Social Security numbers. It has issued over 450 million since the start of the program, about 5.5 million per year. It says it has enough to last several generations without reuse and without changing the number of digits. www.ssa.gov/history/hfaq.html

evidently they must be doing something else on the backend for this to be working, assuming there are quite literally 100M numbers, which is going to be static due to math, obviously, but they clearly can’t be reassigning numbers to 3 people on average at any given time, without some sort of external mechanism.

There are approximately 420 million numbers available for assignment.

that certainly doesnt seem like it would support several generations, possibly at our current birth rate i suppose.

DDG AI bullshit tells me that there are a billion codes. marketplace.org/…/will-we-ever-run-out-of-social-… this article says it’s 1 billion

www.ssn-verify.com/how-many-ssns

this website also lists it as approximately 1 billion.
