Were there at least 3.2 million Illegal Aliens who were issued Social Security numbers by the Biden Administration? 4.9 million non-citizens obtained Social Security numbers.

In some states the last four digits of one’s Social Security numbers are often used for identity verification during voter registration. The number of non-citizens provided Social Security numbers by fiscal year, though this includes both those who can legitimately get numbers as well as illegal aliens.

FY2021 270,425

FY2022 590,193

FY2023 964,163

FY2024 2,095,247

FY2025 October 2024 to March 2025 900,649

Total 4,910,677

Unfortunately, the Social Security numbers don’t break down how many of these non-citizens were illegal aliens? We also don’t know how many of the 900,649 issued during fiscal year 2025 were just from October 2024 through January 2025 nor how many of the 270,425 during fiscal year 2021 were after January 2021.

Assuming the average of 340,481 Social Security numbers granted by year over the fiscal years 2019 to 2021 were all non-citizens legally in the United States, that would be 1,702,408 over five years. So 4.91 million minus 1.7 million or 3.2 million. While it is possible that some of the non-citizens granted Social Security numbers in February and March were illegal aliens and were granted numbers by the Trump administration at the same rate as under Biden, that would amount to 184,855, though that seems extremely unlikely. But that could reduce the number further to over 3 million.
