Westpac SWIFT Code: WPACAU2S and Branch-Specific Codes

Anyone who’s ever tried to send money to Australia from overseas has probably paused at the same screen: “Enter SWIFT code for the recipient bank.” If you’re dealing with Westpac, that code is WPACAU2S — but how you find the right version for your branch and whether you’ll also need an IBAN are questions that trip up plenty of transfers.

Westpac SWIFT code: WPACAU2S (8 characters) or WPACAU2SXXX (11 characters) ·
Bank name: Westpac Banking Corporation ·
Country: Australia ·
Branch-specific codes: Yes, different SWIFT codes for different services ·
IBAN usage in Australia: No, Australia does not use IBAN ·
Common international transfer requirement: SWIFT code + account number

Here is a quick-reference table for Westpac’s SWIFT details.

How do I find out my SWIFT code Westpac?

Locating your Westpac SWIFT code doesn’t require a call to the bank. You have three straightforward options, each backed by Westpac’s own systems. The code you need depends partly on whether you’re receiving a transfer or giving a sender the details.

Locate your SWIFT code in online banking

• Log into Westpac’s online banking platform and navigate to your account details or settings. A “Look Up Bank” function may be available directly in the international transfer section (XTransfer (cross-border payment guide)).
• For most personal accounts, the default SWIFT code WPACAU2S will appear.

Check your bank statement

• Your monthly or quarterly Westpac statement lists the bank’s SWIFT code in the footer or under account details.
• If you have a paper statement from a specific branch, look for any branch-specific code noted alongside the main code.

Use Westpac’s official SWIFT code lookup

• Visit Westpac’s official FAQ on transferring funds (Westpac official) or the international transfers page.
• Alternatively, call Westpac’s customer service – they can confirm the exact code for your account type and branch.

What is Westpac’s SWIFT Code/BIC?

Westpac’s Bank Identifier Code (BIC) is the same as its SWIFT code — both terms refer to the same alphanumeric identifier. The code breaks down into meaningful components that pinpoint the bank’s location and department.

The main SWIFT code: WPACAU2S

Westpac Banking Corporation’s primary SWIFT code is WPACAU2S. This 8-character version is enough for most international transfers. The code identifies the bank globally (Westpac (official international transfers page)).

11-character version: WPACAU2SXXX

Some sending banks require an 11-character code. In that case, use WPACAU2SXXX. The final three characters “XXX” refer to Westpac’s head office in Sydney (Xe (currency exchange and SWIFT lookup)).

What each part of the code means

• WPAC – Bank code for Westpac Banking Corporation.
• AU – Country code for Australia.
• 2S – Location code for Sydney (head office).
• XXX – Optional branch code (default head office).

The pattern: For Westpac in Australia, every SWIFT code starts with WPACAU. The third and fourth characters narrow down the city or department.

Does Westpac use IBAN or SWIFT?

A common question from people used to European banking: “What’s my IBAN for Westpac?” The short answer is that Australia doesn’t use IBAN at all. Westpac relies entirely on SWIFT codes for international transfers.

Australia does not use IBAN

The International Bank Account Number (IBAN) system is standard in Europe and parts of the Middle East, but Australia never adopted it. Westpac customers do not have an IBAN (Westpac (official international transfers page)).

SWIFT is required for international transfers

For receiving money from overseas, the sender must provide Westpac’s SWIFT code (WPACAU2S or its 11-character version) along with your account number (Westpac (official international transfers page)).

What to use when sending money to Westpac

• SWIFT code: WPACAU2S (or branch-specific variant).
• Account number: 6-digit BSB + 6-digit account number (12 digits total).
• Bank name: Westpac Banking Corporation.
• No IBAN required.

Is SWIFT code for every branch?

Westpac maintains different SWIFT codes for different service types and, in some cases, for specific branches. While the main code WPACAU2S works for most transfers, there are exceptions.

Main office vs branch codes

The default code WPACAU2SXXX points to Westpac’s head office in Sydney. However, Westpac operates across Australia, and some branches have their own codes. For example, wealth management services may use a separate identifier (Bank.Codes (SWIFT code directory)).

Westpac uses different SWIFT codes for different services

According to Wise, a global money transfer platform, “Westpac uses different SWIFT/BIC codes for the different types of banking services it offers” (Wise (international transfer comparison platform)). This means the code for everyday personal banking might differ from the code used for business accounts or institutional services.

How to find the correct code for your branch

• Use the “Look Up Bank” function in Westpac’s online banking.
• Contact Westpac customer support and ask them to confirm the SWIFT code for your specific account type.
• Check bank statements – some statements list the applicable SWIFT code for that branch.

The implication: If you’re setting up recurring international payments to a Westpac account, it’s worth verifying whether the sender should use WPACAU2S or a branch-specific code. Using the wrong code can delay payments (Xe (SWIFT code lookup)).

Is IFSC Code the Same as SWIFT Code?

No. IFSC (Indian Financial System Code) and SWIFT codes serve entirely different purposes and operate in different geographic scopes. Confusing the two is a common mistake for people transferring money to India.

Here is a comparison of IFSC and SWIFT codes.

IFSC is used in India for domestic transfers

IFSC codes are assigned to every bank branch in India for the electronic funds transfer systems (NEFT, RTGS, IMPS). They are not used for international payments.

SWIFT is global

SWIFT codes are the standard for cross-border bank identification. Westpac’s code WPACAU2S works across 200+ countries.

Key differences in format and usage

• IFSC always starts with the bank’s alphabetic code (e.g., SBIN for State Bank of India); SWIFT starts with a bank code (WPAC for Westpac).
• IFSC is 11 characters fixed; SWIFT can be 8 or 11.
• They cannot be used interchangeably — sending an IFSC to a non-Indian bank will fail.

What is an IBAN number?

IBAN stands for International Bank Account Number — a standardized numbering system used primarily in Europe to identify individual accounts across borders. It’s not used in Australia, so Westpac customers will never encounter it for domestic or regional transactions.

IBAN definition

An IBAN can be up to 34 alphanumeric characters and includes a country code, check digits, and the domestic account number. It was designed to reduce errors in cross-border payments within the SEPA region and beyond.

Countries that use IBAN

• European Union member states (mandatory for wire transfers).
• United Kingdom, Switzerland, Norway, Turkey, and some Middle Eastern countries.
• Not used in Australia, the United States, Canada, New Zealand, or most of Asia.

Why Westpac customers don’t need an IBAN

Australian banks, including Westpac, do not assign IBANs to customer accounts. When receiving money from overseas, the sender simply needs the SWIFT code and your account number (BSB + account number). If a European bank asks for an IBAN for a transfer to Westpac, explain that Australia uses SWIFT codes instead (Westpac (official international transfers page)).

The pattern: One global system (SWIFT) for identifying banks, another regional system (IBAN) for identifying accounts. Westpac lives entirely in the SWIFT world.

“The SWIFT Code for Westpac is WPACAU2S. If the sending bank requires 11 characters, use WPACAU2SXXX.”

— Westpac (official FAQ)

“Westpac uses different SWIFT/BIC codes for the different types of banking services it offers.”

— Wise (international transfer comparison platform)

For anyone sending money to a Westpac account from overseas, the decision is clear: use the SWIFT code WPACAU2S (or WPACAU2SXXX for 11-character requirements) and your 12-digit account number. Don’t ask for an IBAN — it won’t work. For Australian customers receiving funds, providing the correct SWIFT code upfront saves days of delay. The trade-off: branch-specific codes exist, so a quick verification with Westpac’s online banking or customer support costs five minutes but prevents a week-long headache.
