Of course you can! The identification number (ID) generation system of different countries has its own characteristics, usually including verification mechanism, regional code, birthday information, etc. The following are a few examples of typical countries and their algorithm logic： --- ### **1. Chinese resident ID card (18 digits)** -**Format **: `6-digit area code' + '8-digit birthday (YYYYMMDD)' + '3-digit sequence code' + `1-digit check code` -**Check code algorithm** (ISO 7064:1983 MOD 11-2)： 1. The first 17 digits are multiplied by the weight coefficient `[7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2]`. 2. Calculate the weighted sum's`, find'smod 11'to get the remainder'z`. 3. Get the check code according to the comparison table of the remainder'z` ('z:0-10' →`Check code:1,0,X,9,8,7,6,5,4,3,2`）。 -**Example**: Suppose the first 17 digits are`11010519491231002`, calculated as'z=9', the check code is`3`, and the full ID is`110105194912310023`. --- ### **2. U.S. Social Security Number (SSN, 9 digits)** -**Format **: `3-digit area code' + '2-digit group number' + `4-digit serial number` -**Rules**： -The generation algorithm is not disclosed, but the number must meet a certain range (for example, the area code does not contain `000`, `666` or `900-999`). -Historically used in taxation and social security, some fields are now randomized to prevent leakage of information. -**Example**: `123-45-6789` (Note: This is a public test case, and the real SSN needs to be kept confidential). --- ### **3. French INSEE code (15 digits)** -**Format **: `1 gender (1 male/2 female)' + '6 birthdays (YYMMDD)' + '5 place of birth codes' + '3 sequence codes` -**Check code**: There is no independent check digit, but the validity can be verified by an algorithm (such as birthday and area code need to be legal). --- ### **4. Korean resident registration number (13 digits)** -**Format **: `6-digit birthday (YYMMDD)' + '1-digit gender code (century/gender)' + '4-digit area code' + '1-digit check code` -**Check code algorithm**： 1. The first 12 digits are multiplied by `[2,3,4,5,6,7,8,9,2,3,4,5]`. 2. Calculate and 's`, find `(11-(S mod 11)) mod 10' to get the check code. --- ### **5. Japan My Number (12 digits)** -**Format **: `11-digit random number' + `1-digit check code` -**Check code algorithm**： 1. The first 11 digits are from right to left, the odd digits are multiplied by `1`, and the even digits are multiplied by `2`. 2. Calculate each number and 's`, and the check code is `(10-(S mod 10)) mod 10'. --- ###**Features of general verification algorithm** -**Prevent errors**: Avoid input errors through check codes (such as the Luhn algorithm used for credit cards). -**Privacy protection**: Modern systems tend to de-identify and reduce direct exposure of personal information. --- ###**Precautions** -Most of the above algorithms are public logic, but the actual generation may involve more complex rules (such as blacklist filtering). -**Forgery is strictly prohibited**: ID card generation is only used for learning, and real scenes must be used strictly in accordance with the law.
