About the Austrian SVNR
The SVNR is the Austrian personal social insurance number, mandatory for employment, pension, healthcare, and tax reporting.
Every citizen or resident in Austria is assigned a permanent SVNR by the relevant social security institution.
Austrian SVNR Anatomy
The Austrian SVNR consists of 10 digits with a built-in 4th-position checksum:
| Position | Field | Length | Meaning & Rule | Example |
|---|---|---|---|---|
| 1 to 3 | Serial Number | 3 digits | Daily sequence assigned by the social insurance institution | 123 |
| 4 | Check Digit (P) | 1 digit | Modulo 11 positional checksum (weights 3,7,9,0,5,8,4,2,1,6) | 7 |
| 5 to 10 | Birth Date | 6 digits | Date formatted as DDMMYY | 010180 |
Official SVNR Modulo 11 Algorithm
Calculation defined by the Austrian Main Association of Social Security Institutions:
Sum = Σ(d[i] * w[i]) with w = [3, 7, 9, 0, 5, 8, 4, 2, 1, 6]; P = Sum mod 11 (Remainder 10 is invalid).
- 1. Multiply each of the 10 digits by weights [3, 7, 9, 0, 5, 8, 4, 2, 1, 6].
- 2. The 4th position (index 3) has weight 0 during verification.
- 3. Sum the products and calculate the remainder modulo 11.
- 4. The remainder must match the 4th digit exactly.
- 5. If the remainder is 10, that sequential number combination is officially discarded.
