To generate ID card numbers and related virtual information that comply with the rules, you need to understand the ID card coding rules, but it must be emphasized: **This technology can only be used for legal testing purposes and is prohibited from being used for any illegal activities. When generating virtual identity information, it is necessary to comply with the relevant provisions of the "Personal Information Protection Law"**. The following are the technical implementation ideas： --- ###1. The principle of ID number generation (18-digit structure) 1. **Address code (6 digits)**: Use the latest administrative division code of the National Bureau of Statistics (need to be updated regularly) 2. **Date of birth (8 digits)**: Valid date in YYYYMMDD format 3. **Sequence code (3 digits)**： -The first 2 digits: police station allocation code -3rd place: gender code (odd male, even female) 4. **Check code (1 digit)**: Calculated from the first 17 digits --- ###2. Core code implementation steps (Python example) #### 1. Administrative division code processing ```python # Need to download the latest administrative division code from the official website of the National Bureau of Statistics area_codes = [ "110101", #Dongcheng District, Beijing "440304",#Futian District, Shenzhen # . . . Other valid zoning codes ] ``` #### 2. Date of birth generation ```python from datetime import datetime, timedelta import random def generate_birthdate(min_age=18, max_age=60): start = datetime. now() - timedelta(days=max_age*365) end = datetime. now() - timedelta(days=min_age*365) random_date = start + (end - start) * random. random() return random_date. strftime("%Y%m%d") ``` #### 3. Check code calculation (ISO 7064:1983 standard) ```python def calculate_check_code(id17): weight = [7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2] check_map = "10X98765432" total = sum(int(a)*b for a,b in zip(id17, weight)) return check_map[total % 11] ``` #### 4. Complete generation function ```python def generate_id_card(): # Randomly select administrative divisions area = random. choice(area_codes) # Generate date of birth birth = generate_birthdate() # Generate sequence code order = f"{random. randint(0,99):02d}{random. randint(0,9)}" # Combination of the first 17 digits id17 = area + birth + order # Calculate the check code check = calculate_check_code(id17) return id17 + check ``` --- ###3. Generate virtual details ```python import random From faker import Faker # Need to install the faker library def generate_fake_info(): fake = Faker('zh_CN') id_num = generate_id_card
