Australian Individual Healthcare Identifier (IHI) Regex for Python

What this pattern does

This page provides a lightweight, single-purpose regular expression for matching australian individual healthcare identifier (ihi), ported and verified for Python. Identity and credential patterns need both correctness and safety, since they're frequent targets for adversarial input. The snippet below is ready to drop into your Python project — whether you're validating in a Django view, a FastAPI endpoint, or a standalone data processing script.

Python Implementation

# Australian Individual Healthcare Identifier (IHI)
# ReDoS-safe | RegexVault — Identity & PII > Health Identifiers

import re

australian_individual_healthcare_identifier_ihi_pattern = re.compile(r'^800360[0-9]{10}$')

def validate_australian_individual_healthcare_identifier_ihi(value: str) -> bool:
    return bool(australian_individual_healthcare_identifier_ihi_pattern.fullmatch(value))

# Example
print(validate_australian_individual_healthcare_identifier_ihi("8003601234567890"))  # True

Test Cases

When to use this pattern

This pattern is drawn from the Identity & PII > Health Identifiers category and carries a ReDoS-safe certification. That matters for Python developers because particularly important in Python web servers where CPU-bound regex operations can stall concurrent request handling. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.
