Overview

Bank Account Validation is a web service that uses an algorithm to validate the bank account number, branch code, and account type combination. Any software that allows for the capture of bank account details this web service as it ensures valid data is sent to Netcash will enhance the success of transactions processed. This service does not verify that the account is active or belongs to the individual or company (Bank Account Verification).

We recommend that Universal Branch Codes are used for the validation to be optimized.

CDV validation is performed using a combination of the bank account number, account type, and branch code.
It is an algorithm supplied to Netcash -and continuously updated by the banking system.
This does not guarantee the validity or existence of the account number at any bank or branch, the account holder -or
if the account is active.

We suggest that you first validate -and then verify the account holder’s details to ensure accuracy.

Recommended User Experience

  1. Call the web service with method GetBankListWithDefaultBranchCode
    or
  2. Manually create a table in the application database with the bank branches and codes as indicated above.

The suggested method is to create a user experience whereby the user will

  • Select a bank in a  “Drop down” menu and prefill branch code text box and
  • Manually enter a branch code that is not a CBC.
  • If the bank required is not in the dropdown – user to select “other bank” and type the six (6) digit numeric branch code in the text box. Left-pad the input with “0” where data entered is less than 6 chars.
  • Netcash will offer all blue and bold items above as “dropdown list” in our systems.
  • For all black items above default account type in the database to 1 (cheque/current) except
    • for Nedbank
      • If a Nedbank account number starts with ‘2’ make type 2 (savings) else
      • If Nedbank account number starts with ‘1’ leave type 1 and
      • If a Nedbank account number starts with ‘9’/or is a Corporate Saver Account; make the account type 2 (savings) and only use branch code 720026.
    • for Postbank / Capitec / TymeBank

      • Always use account type “2” (savings) for all Postbank, Capitec and TymeBank transactions

All non-listed (above) banks – user to select the actual account type (1 = Current/Cheque, 2 = Savings)

  File.WriteAllText("BankList.xml", BankListResult);

  XmlDocument XmlDoc = new XmlDocument();

  XmlDoc.Load("BankList.xml");

  XmlElement XmlEl = XmlDoc.DocumentElement;
