Your NAB ID and Telephone Banking password

For quick and easy access to NAB Telephone Banking and related services you need your NAB Identification Number (NAB ID) and Telephone Banking password. They give you highly secure access to conduct your banking. They also enable our staff to assist you most efficiently, protect your privacy and help to protect you against identity theft.
Important: Never disclose your telephone banking or internet banking password over the phone or email. Find out more.

Manual authentication if you forget your password

After three unsuccessful attempts using your telephone banking password you will be referred to a Customer Service Representative for manual authentication. We will need to identify you via a series of security questions that only you should know. To help protect you from identity theft, NAB only allows you to reset your password once over the phone. If you require your password to be reset again, we will post you a letter and you may also need to visit a branch to be identified in person.

Telephone banking transaction monitoring

NAB takes your security seriously by taking several steps to ensure your money is safe and secure. Find out more about NAB Internet Banking and NAB Telephone Banking transaction monitoring.

BPAY biller limits to minimise the risk

When you make payments to certain BPAY® billers, the biller can withdraw those funds as cash or forward them straight away, for example, when you make a BPAY payment to a credit card or TAB account. Because of the fast access to the funds, these accounts can become a target for fraudulent activity.

To minimise the risks of fraudulent activity and safeguard your money while you are using Internet Banking, customers who are not registered for SMS Security will have BPAY® Bill payments (except payments made to NAB authorised billers) included within their daily transfer limit of $2,500.

But don’t worry – this doesn’t affect NAB authorised billers such as gas, water and electricity providers, and government departments.

Payments made to NAB authorised billers can be performed up to the maximum amount imposed by the biller and are not included with the daily transfer limit. Note: The biller can advise any transaction limits they have imposed.

Customers are advised in internet banking when a bill payment is being made to a NAB authorised biller.

®BPAY is registered to BPAY Pty Ltd ABN 69 079 137 518.

Key tips to help protect against telephone banking fraud and identity theft

In addition to NAB’s world-class security solutions, here are some simple tips to help you protect your personal information.


  • Exercise good password management.
    That includes keeping it a secret, changing it regularly (we recommend monthly), not recording it anywhere and making it known ONLY to you.
    Do not use your date of birth, telephone number, address or other easily known personal information as your password.
    Make sure you are not observed when entering your telephone banking password.
  • Pause and think. If it looks too good to be true, then it most likely is. If you receive a phone call/email or view a website that looks suspicious, don't proceed and ask for assistance by calling 1300 651 656.
  • Destroy personal information. Shred, tear or cut up documents such as bills and account statements before throwing them away.
  • Lock your letterbox. If you are away for an extended time, have your mail held at the post office.
  • Sign cards immediately. Sign all credit and debit cards as soon as you receive them.
  • Check you've received all your expected bills and statements. A missing letter could indicate a thief took it from your letterbox or changed your billing address.
  • Securely store personal information. At home, secure information such as details of your credit cards, debit cards, bank accounts and investments – the account numbers, expiration dates and emergency contact details. Do not store this information in your wallet, purse or car glove box.
  • Keep your receipts and check your account statements immediately. Follow-up any unfamiliar transactions. When shopping, put your receipts in your wallet rather than in the shopping bag.
  • Update your contact information. If you move house or change telephone numbers tell your bank, card issuer and other organisations immediately so that you receive your bills and they can contact you if they notice suspicious activity on your account.
  • Consider limiting the amount of credit you have in your account. Also consider whether it may be safer to use a separate credit card account for online transactions and when you are overseas as there may be a higher risk of fraud occurring.
  • Additional passwords. Password-protect your mobile phone, laptop, PDA and other electronic devices.
  • Read the privacy policy. Before providing information to any business make sure you understand how protected your data will be.
  • Collect your new credit card and cheque books in person. If that is not possible, watch out for them and phone your bank if they haven’t arrived when expected.
  • Hang up. Always remember to hang up the phone immediately after you have finished your banking.
  • Do not provide personal or financial information to little-known or suspect websites. It is also a good idea to limit the personal details you provide on well known websites such as MySpace and Facebook as this may assist fraudsters in obtaining personal information about you.

Identity theft explained

Identity theft and identity fraud refer to crimes where someone wrongfully obtains and/or uses another person’s personal data in a way that involves fraud or deception, typically for financial gain. If you’re a victim, someone else has the ability to misuse your identity and access your money.

Identity theft involves the theft of a pre-existing identity. It may occur when a criminal steals or comes into possession of your personal information, such as your name, credit or debit card details, address, date of birth, bank account number, driver’s license etc. and assumes your identity to commit fraud.

Identity theft can range from a criminal using your credit card details illegally to make purchases over the internet or telephone, through to having your entire identity assumed and used to open bank accounts, take out loans, run up unpaid bills, lodge tax returns and conduct other business illegally in your name. When someone assumes your identity it is known as ‘identity takeover’ and it is on the increase.

Every day, you engage in transactions that require the sharing of personal information. You may share personal details when you pay bills, make purchases, hire a car, rent accommodation, open bank accounts or log on to a computer. To complete these transactions, you often provide information such as your name, address, phone number, driver's licence number, or sometimes even bank account or credit card numbers.

To protect yourself, be careful when providing personal or financial information to organisations or people you know little about, and review transactions on your bank and credit card statements on a timely basis.
