Generating a legal Social Security Number (SSN) involves certain compliance and legal issues. In the United States, the Social Security Number is an important identifier of personal identity. Randomly generating or using an invalid SSN may involve illegal behavior. Therefore, the code I provide is only for learning and understanding the format of SSN, and is not recommended for actual generation and use. The format of the US Social Security Number is XXX-XX-XXXX: - The first three digits (XXX): consist of numbers between 0-899. 0 is illegal as the first digit, and numbers 900-999 are usually reserved for temporary and special purposes. - The middle two digits (XX): can be numbers between 00 and 99. - The last four digits (XXXX): can be numbers between 0000 and 9999. Here is a Python example that shows how to generate Social Security numbers that conform to the format, but be sure to use this code within a legal framework: ```python import random def generate_ssn(): # The first three digits first_part = random.randint(100, 899) # A random number from 100 to 899 # The middle two digits second_part = random.randint(0, 99) # A random number from 00 to 99 # The last four digits third_part = random.randint(0, 9999) # A random number from 0000 to 9999 ssn = f"{first_part:03}-{second_part:02}-{third_part:04}" return ssn # Generate legal Social Security numbers in batches def generate_multiple_ssn(n): ssns = set() # Use sets to avoid duplicate SSNs while len(ssns) < n: ssns.add(generate_ssn()) return list(ssns) # Generate 10 valid social security numbers generated_ssns = generate_multiple_ssn(10) for ssn in generated_ssns: print(ssn) ``` Please ensure that your use complies with relevant laws and regulations and will not be used for illegal purposes.
