Bank Account Validate

Heimdall is a Python package which validates the main brazilian banks: Itaú, Bradesco, Caixa, Banco do Brasil, Citibank, Santander, Banrisul and Nubank. For the remaining ones it is used a default validation:

  • Agency is required to have 1 up to 5 digits
  • Agency Branch is required to have 0 up to 2 characters
  • Account is required to have 1 up to 12 digits
  • Account Branch is required to have 0 up to 2 characters

Basic Usage

Install with pip:

pip install wheel && pip install heimdall_valid_bank

To validate the entire bank account, follow these steps:

from heimdall_valid_bank.data_bank_validate import DataBankValidate

valid_bank = DataBankValidate(
                bank_code='001',
                agency='1584',
                digit_agency='9',
                account='00210169',
                digit_account='6'
            ).start()

if valid_bank == True:
    print('Bank Valid')
else:
    print('Bank Invalid')

You can also validate in stages, using BankValidate, AgencyValidate, AccountValidate,:

Examples:

  • basic agency validation:
from heimdall_valid_bank.agency_validate import AgencyValidate

valid_bank = AgencyValidate(
                bank_code='237',
                agency='2377-8'
            ).start()

if valid_bank == True:
    print('Agency Valid')
else:
    print('Agency Invalid')
  • validation with agency branch
from heimdall_valid_bank.agency_validate import AgencyValidate

valid_bank = AgencyValidate(
                bank_code='001',
                agency='1584',
                digit_agency='9'
            ).start()

if valid_bank == True:
    print('Agency Valid')
else:
    print('Agency Invalid')
  • agency validation by passing the branch directly at the agency, if you have:
from heimdall_valid_bank.agency_validate import AgencyValidate

valid_bank = AgencyValidate(
                bank_code='001',
                agency='1584-9'
            ).start()

if valid_bank == True:
    print('Agency Valid')
else:
    print('Agency Invalid')
