PayID is a payment service that lets Australians send and receive money using a memorable identifier instead of a BSB and account number. It’s built on the New Payments Platform — the real-time payment infrastructure that Australia’s major banks developed collaboratively — and it’s been available since February 2018. If you haven’t used it yet, the setup takes about three minutes and the benefits are immediate.
The fundamental idea is simple: rather than asking someone for their six-digit BSB and eight-digit account number — a sequence people regularly mistype — you give them a PayID. A PayID can be your mobile phone number, email address, or ABN (for businesses). It acts as an alias for your bank account. When someone sends money to your PayID, the banking system looks up which account it’s registered to and routes the transfer accordingly.
Setting up PayID is done through your bank’s mobile app or internet banking. Navigate to the PayID or payments section — the exact location varies by bank but is usually under settings or account management. Enter the identifier you want to register — your mobile number is the most common choice. Your bank verifies ownership by sending a confirmation code to that number. Once you enter the code, the PayID is live and active. There’s no cost to register or maintain a PayID.
Sending money via PayID is just as straightforward. In your banking app, start a new payment and choose PayID as the transfer type rather than entering a BSB and account. Enter the recipient’s PayID — their number or email address. Your app will display the name registered to that PayID so you can confirm you’re sending to the right person before proceeding. Enter the amount, add an optional description, and confirm. The money leaves your account instantly and arrives in the recipient’s account in real time.
The speed is the most immediately noticeable difference from older transfer methods. Traditional bank transfers — particularly to other banks — used to take one to three business days due to batch processing windows. PayID transfers settle in seconds, any time of day or night, including weekends and public holidays. The NPP has no offline windows; it processes continuously.
For people using what is pay id searches to understand the service, the practical applications extend well beyond peer-to-peer payments. Businesses use PayID to receive payments from customers — a plumber might give their phone number as a PayID rather than asking customers to set up a new payee with account details. Online platforms, including many online casinos in Australia, use PayID to receive customer deposits because it’s fast and the payment confirmation is automatic.
The confirmation of payee feature is a meaningful security addition. When you send to a PayID, your app shows the name registered to that identifier before you confirm. This lets you catch errors — sending to the wrong number — or verify the recipient’s identity before committing. If the name shown doesn’t match who you expect, stop and confirm separately before proceeding.
One important characteristic to understand: PayID transfers are irrevocable once sent. Unlike a credit card purchase where you have chargeback rights, or a bank transfer where you can sometimes request a recall if caught quickly, a PayID payment that arrives in the recipient’s account is final. This is why the confirmation of payee check matters — it’s your last opportunity to verify the destination before a transaction that can’t be reversed.
PayID works across all participating financial institutions in Australia, which now includes virtually every bank, credit union, and building society. You can send from a Commonwealth Bank account to a Westpac account, or from a small credit union to any major bank, instantly and for free. The interoperability is built into the NPP architecture — it’s a genuine national payment infrastructure, not a service that only works within a single bank’s network.
Multiple PayIDs can be registered to a single account — your mobile number and your email address can both point to the same account if you prefer. You can also change which account a PayID points to without deregistering it, though there’s a cooling-off period to prevent fraudulent redirections. Managing your PayIDs through your bank’s app gives you full control over which identifiers are active and which account they link to.
