Superannuation identifiers

Detects Australian superannuation identifiers with populated values: USI (unique superannuation identifier), fund member/account numbers, fund or SMSF ABN and SMSF electronic service address (ESA), optionally with the member or employee name.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium: USIs, member numbers and SMSF ESAs have no single verified public format, so the classifier anchors on a labelled identifier with a populated value that contains a digit (placeholder-guarded) near a superannuation identifier phrase for 75, and adds a populated member/employee name plus independent corroboration for 85. 85/75 are heuristic evidence tiers, not measured accuracy.
Detection quality: Topic false positive
Jurisdictions: au
Regulations: Superannuation Guarantee (Administration) Act 1992 (Cth), Superannuation Industry (Supervision) Act 1993 (Cth), Taxation Administration Act 1953 (Cth), Privacy Act 1988 (Cth), Information Privacy Act 2009 (Qld)

Known false positives

Policies, procedures, regulator guidance, fact sheets and training material that name the record type. Mitigation: Enforce tiers require populated fields; guidance has labels without values, and policy/guidance/training/media-release framing is excluded by the NOT-group.
Blank forms, templates and system configuration screens. Mitigation: Blank lines, bracket placeholders, XXX and n/a/tbc values are rejected by the placeholder guard; template/fixture words are excluded by template-exclusion.
Public fund product listings that publish fund ABNs and USIs. Mitigation: Fund ABN/USI alone is public data and stays at 75; 85 needs a populated member name plus corroboration.
Overlap with au-tfn-declaration-super-choice-form, au-superannuation-fund-number and superannuation-fund-member-statement-bulk. Mitigation: This pattern detects identifiers in any record; the choice-form and bulk-statement classifiers carry the form/bulk context.
