The claim appears to refer to the Enumeration Beyond Entry (EBE) process, which is a legal way to assign Social Security numbers to eligible noncitizens, not ā€œillegal migrants.ā€ Based on the figures reported in the sources I found, the total under Bidenā€™s presidency was about 3.92 million SSNs, with 2,095,247 in fiscal year 2024 alone.

What the numbers show

The reported annual figures were roughly:

  • 2021: 270,425.
  • 2022: 590,193.
  • 2023: 964,163.
  • 2024: 2,095,247.

That adds up to about 3,920,028 over those four years.

Important context

The program described in the reporting is for people with lawful work authorization, permanent residency applications, or naturalization applications, so the SSNs were not issued simply because someone entered the country unlawfully. One fact-check also notes that the program began in 2017 and expanded later, which helps explain the increase in the later years.

Bottom line

So, the most defensible answer is: about 3.92 million Social Security numbers were issued through this process during Bidenā€™s presidency, according to the reported figures. The claim that this means ā€œmillions of illegal migrantsā€ got SSNs is not supported by the context in the reporting.
