Australia BSB Number Validation

Validate Australian BSB numbers and identify bank, state, branch, address, and postcode information. This page follows the same clean UI as the main site while giving developers a focused validation guide.

A code can be checked before a payment is created, helping teams prevent failed transfers, manual repair work, delays, and support tickets.

For example, use 082-024:

  • 08 - bank code
  • 2 - state code
  • 024 - branch code

How to validate

Start by creating an API key. Pass this key with the x-api-key HTTP header or with the api_key query parameter.

curl 'https://api.ibankdata.com/v1/bsb/082024' \
  --header 'X-Api-Key: your-api-key-here' \
  --header 'Accept: application/json'

The response should be:

{
  "success": true,
  "data": {
    "id": "082-024",
    "bank": {
      "name": "Example National Bank",
      "code": "EXNB",
      "country_id": "US"
    },
    "branch_name": "Main Office",
    "city": { "name": "New York" },
    "address": "100 Finance Avenue",
    "postcode": "10001"
  }
}
