Comprehensive Australian government identifier detection. Covers tax, healthcare, immigration, welfare, education, and business identifiers.
Identifies Australian Bank State Branch (BSB) routing codes in 3-digit dash 3-digit or continuous 6-digit formats. Supports space separator. Requires corroborative financial-institution keywords.
Detects Australian Business Numbers (ABNs), which are unique 11-digit identifiers issued by the Australian Business Register to entities carrying on a business in Australia. ABNs are commonly formatted as groups of 2-3-3-3 digits separated by spaces or hyphens. The ABN includes a check digit mechanism, but this pattern relies on format matching combined with corroborative evidence rather than algorithmic validation.
Detects candidate Centrelink Customer Reference Numbers consisting of 9 digits followed by a letter. The bare shape is not unique and requires a CRN/Centrelink label for enforcement.
Detects Australian Citizenship Certificate number patterns including prefixed formats (ACC, CDM, ACS, CAS followed by 4-8 digits) and numeric-only formats (0 + 10 digits).
Detects Australian Company Number patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.
Detects Individual Healthcare Identifier (IHI) patterns. The IHI is a 16-digit number starting with the prefix 800360; the official format carries a Luhn check digit (not enforced here).
Detects Australian Medicare card numbers, which are issued to Australian citizens and permanent residents for access to subsidised healthcare under the Medicare system. The number consists of 10 digits: the first digit is between 2 and 6, followed by 8 additional digits and a single check digit. Numbers are commonly formatted as groups of 4-5-1 digits separated by spaces or hyphens.
Detects Medicare Provider Number patterns. An 8-character code consisting of 6 digits, a location character, and a check character. Validated by location and check character sets.
Discovery-only compatibility coverage for Australian driver's licence number candidates across all states and territories. The stable au-motor-vehicle-permit slug is retained for catalogue, collection, workbook, and package compatibility. State and territory enforcement belongs to the eight au-*-driver-licence-number SITs. Microsoft Purview tenants can instead select the free built-in Australia Driver's License Number entity (1cbbc8f5-9216-4392-9eb5-5ac2298d1356); this compatibility pattern is not a custom clone of that built-in.
Detects NDIS Participant Number patterns. A 9-digit number starting with the prefix 43.
Detects PBS Prescriber Number patterns. A 7-digit number whose check digit uses weights [0,5,8,4,2,1], mod 11 (checksum NOT enforced in this regex-only pattern; structural detection only).
Identifies Australian Tax File Numbers (TFNs) — unique nine-digit identifiers issued by the Australian Taxation Office. Uses an inline mod-11 Checksum validator with AllDigitsSameFilter and TextMatchFilter to exclude known test values.
Identifies candidate Australian passport numbers using a broad one- or two-letter prefix followed by seven digits. The regex does not validate an issued passport series; Australian travel-document and issuing-nation evidence are required for enforcement.
Detects Unique Student Identifier (USI) patterns. A 10-character alphanumeric code (uppercase letters and digits) mandatory since January 2023 for higher education in Australia. The Purview design inventories the broad bare shape at 65, enforces a labelled value in education context at 75, and reserves 85 for labelled values with authoritative USI/VET record context.
