⚙️ The SSN Format Validation Algorithm
This is the most you can do without calling an external service. The process checks if a given SSN string adheres to the standard format and avoids known invalid number ranges. The core of this process is often a regular expression (regex) that checks for specific patterns and invalid combinations.

1. Basic Format and Length
A valid SSN must have nine digits. It's most commonly presented in the format AAA-GG-SSSS (Area-Group-Serial).

AAA (Area): The first three digits.

GG (Group): The next two digits.
