What is a Unique Superannuation Identifier (USI)?

A Unique Superannuation Identifier, or USI, is a number used to identify super funds and individual super fund products for electronic rollovers and contributions, including as part of SuperStream.

A super fund may have one USI, or it may have a USI for each product. Compare this to the ABN, which is per fund.

The USI is used as part of the SuperStream payment standard for transfer of electronic data about employer superannuation contributions.

With the SuperStream changes super funds may choose to use a Superannuation Product Identification Number (SPIN) as a USI. The USI can also be the fund’s ABN followed by three digits.

The ATO Standard Choice Form says, for APRA funds, “you must include the unique superannuation identifier (USI) provided by your fund.” This does not apply if nominating an SMSF.

A register of USIs, and associated bank details and IP addresses, is maintained by the ATO in order to run the system.

How to find a super fund’s Unique Superannuation Identifier

Where required, the ATO has recommended searching on the super fund website for the USI. It can also often be found on the Letter of Compliance.

The ATO has published the USI and SPIN Lookup Table to assist employers find fund data in order to make contributions under the SuperStream system. The table lists the following information for large APRA-regulated super funds:

  • ABN
  • Name
  • USI
  • SPIN
  • Product Name
  • Contribution Restrictions

  1. Thanks for the information! I have an SMSF that requires a unique superannuation identifier. At first, I was worried about finding a USI, so it’s good to know that SMSFs don’t have one. It’s a good thing that you noted that I’ll need my ABN, bank account details, and my ESA so that I can get to work on gathering that information!

  2. Thanks for sharing all of this information about the unique superannuation identifier. I think it is really nice that this form of identification can help you identify specific products as well as contributions and funds. Plus, the fact that you can use the ABN, product name, and SPIN makes it a lot easier for anyone to find the products they are looking for. Thanks again for sharing this information!

  3. From a novice here. Are providers allowed to use USI numbers for life insurance only? I have a policy that has superannuation plastered all over it but its seems to be just a life insurance policy with no retirement benefits at all.
