Essentially, the business license number and the unified social credit code are two completely different coding rules, and the recognition results are only shared by the administrative divisions. But because of the reasons for the coexistence of the two codes, if it is necessary to uniquely mark an enterprise in the system, it is still possible to use the business license number or the unified social credit code. Recognition.
The length of business license number is 15 bits according to industrial and commercial regulations, and the uniform social credit code is 18 bits according to national regulations. You can use other websites (e.g. on the basis of verification of such databases). Enterprise check ) To further verify the existence of enterprises.
In NumberValidators, this section validates the relevant content under NumberValidators. Business Registration Nos. You can use here See the specific source code.
IRegistrationNoValidator agrees on the specification of the validation to be implemented.
/// <summary>

}Verification results are defined as follows:
- RegistrationNoValidationResult default validation result class
- RegistrationNo15 Validation Result Business License Specific Validation Results Class
- RegistrationNo18 Validation Result Unified Social Credit Code Specific Validation Result Class
The RegistrationNoValidation Result code is as follows
/// <summary>

}Registration No15 Validation Result includes the exclusive identification information of business license on the basis of Registration NoValidation Result, through which you can know whether the enterprise is a domestic enterprise, a foreign enterprise or an individual.

}
}Registration No18 Validation Result is based on the Registration NoValidation Result, which contains the exclusive information of the social unified credit code, through which you can know the registration management department and its organization code.

}Consistent with other validation classes, RegistrationNoValidator Helper can automatically identify whether the number to be identified is a business license number or a social unified credit code. Of course, because it is possible to identify which number is not, the final identification results may be in RegistrationNoValidation Result, RegistrationNoValidation Result and RegistrationNo18Validation Result. One of them.
Finally, a simple use example
Console.WriteLine("***Business Registration Code/Unified Social Credit Code***");
string[] rnArr = { "110108000000016", "91320621MA1MRHG205" };
foreach (var rn in rnArr)
{
var valid = RegistrationNoValidatorHelper.Validate(rn, validLimit: null);
Console.WriteLine("{0}Verification results:{1} length{2} Name of administrative division({3}) Validation result type:{4}", rn, valid.IsValid, valid.RegistrationNoLength, valid.RecognizableArea.FullName, valid);
}
Console.WriteLine("Random Business Registration Code:" + new RegistrationNo15Validator().GenerateRandomNumber());
Console.WriteLine("Random Unified Social Credit Code:" + new RegistrationNo18Validator().GenerateRandomNumber());
