New Zealand Business Number Validator

Python package that consumes a NZBN and returns either True or False depending on whether the NZBN Number is valid or not.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

If you would like to create your own package follow the guide below:

Installing

pip install git+https://github.com/danielcerezodev/NZ_Business_Number_Validator.git

Usage

from NZ_Business_Number_Validator import is_valid

nzbn_number = "9876543210123"

is_nzbn_number_valid = is_valid(nzbn_number)

if is_nzbn_number_valid:
    print(nzbn_number + " is valid")
else:
    print(nzbn_number + " is not valid")

How the validation is done

The following steps are performed:

  • Check the valid amount of digits
    • If the NZBN does not contain exactly 13 digits the number is invalid.
  • Check the leading digit
    • If the first digit of the NZBN is NOT a 9, the number is invalid.
