About the Australian Medicare Card
Medicare is Australia's universal healthcare system administered by Services Australia. It provides access to free hospital care, subsidized doctor visits (Medicare Benefits Schedule), and reduced-cost prescription medications (PBS).
The 10-digit number identifies the family card account, while an Individual Reference Number (IRN) on the side identifies individual family members listed on the card.

Official Algorithm (Weighted Modulo 10 — Medicare Australia)
Check digit calculation for Australian Medicare Card:
S = Σ d[i] * W[i] (i=0..7); DV = S mod 10
- 1. Multiply the first 8 digits by weights: W = [1, 3, 7, 9, 1, 3, 7, 9].
- 2. Sum all products into total S.
- 3. Check digit equals remainder of S modulo 10 (DV = S mod 10).
- 4. Ensure first digit is 2-6 and 10th digit (issue number) is 1-9.
