When you send money with Remoly Invoicing, you may need special banking codes depending on the destination country or transfer type. These codes make sure your payment reaches the right bank and account. This guide covers SWIFT, IBAN, and the different local codes used in each country.

SWIFT Codes

A SWIFT code is an international bank identifier used for cross-border payments.

  • Length: 8 to 11 characters

  • Structure:

    • Bank code (4 letters)

    • Country code (2 letters)

    • Location code (2 characters)

    • Branch code (3 characters, optional)

You can look up SWIFT codes at swiftref.com, but it’s always safest to confirm with the recipient’s bank before making a transfer.

Local Codes by Country

Australia

I. BSB Number

A BSB is a 6-digit code used to identify a bank and branch within Australia.

  • First 2 digits = bank

  • Third digit = state

  • Last 3 digits = branch

You can check the BSB on the recipient bank’s website. Here are links for the four largest banks:

II. BPAY

BPAY is an electronic payment system in Australia that allows transfers to registered billers. To use BPAY, you’ll need the biller code and a reference number. Remoly Invoicing can support tuition payments and other bills through BPAY.

United States

ABA Routing Number

The ABA number is a 9-digit code created by the American Bankers Association. It identifies banks in the U.S. for local payments.

  • Also called a routing number, RTN, or check routing number.

  • The number may change based on the state or the type of transaction.

You can find the ABA number on the bank’s website. Helpful links:

China

The CNAPS (China National Advanced Payment System) code is 12 digits long and used to identify banks in China.

  • 3 digits = bank code

  • 4 digits = city code

  • 4 digits = branch code

  • 1 digit = verification code

II. Bank and Area Codes

Alternatively, payments can use:

  • Bank code (3 digits) – identifies the bank

  • Area code (4 digits) – identifies the city of the branch

United Kingdom

Sort Code

The UK uses a sort code, a 6-digit number written as three pairs (e.g., 12-34-56). It identifies both the bank and the branch.

  • In some cases, the first digit shows the bank.

  • In others, the first two digits identify the bank.

Japan

Zengin Code

The Zengin code is used for domestic transfers in Japan.

  • 4 digits = bank code

  • 3 digits = branch code

Singapore

Bank Code

Singapore’s bank code has 7 digits:

  • 4 digits = bank code

  • 3 digits = branch code

Hong Kong

Bank Code

Hong Kong uses a 3-digit bank clearing code. Adding the branch code before the account number helps direct the payment to the right branch.

Europe

IBAN

The International Bank Account Number (IBAN) is the standard format for accounts in Europe and many other regions. It simplifies cross-border transfers by including:

  • Country code

  • Bank code

  • Account number

Most banks in Europe provide an IBAN. Remoly Invoicing also issues IBANs for EUR Global Accounts.
