What is the Sozialversicherungsnummer and what is it for
The Sozialversicherungsnummer (SVNR, also called Rentenversicherungsnummer or RVNR) is a 12-digit personal identifier issued by Deutsche Rentenversicherung (Germany's statutory pension insurance body). It is permanently assigned to you — it never changes, even if you change jobs, move cities, or leave and return to Germany.
Your SVNR is used to:
- Track your social insurance contributions (pension, health, unemployment, long-term care) across all employers
- Calculate your future pension entitlements
- Identify you to all four branches of the German social security system (Rentenversicherung, Krankenversicherung, Arbeitslosenversicherung, Pflegeversicherung)
Your employer is legally required to report your SVNR to the social insurance bodies. Without it, they cannot correctly report your pension contributions.
Format: 12 digits structured as: 65 DDMMYY A XXX V
- 65 — issuing authority code
- DDMMYY — day/month/year of birth
- A — first letter of birth surname
- XXX — serial number
- V — check digit
Example: 65 010190 M 001 3 for someone born 01.01.1990 with surname starting with M.
Sozialversicherungsnummer vs Steuer-ID: the key difference
These are two separate numbers that both go on employment forms. They are issued by different authorities and serve different purposes.
| Sozialversicherungsnummer (SVNR) | Steuer-ID (Steueridentifikationsnummer) | |
|---|---|---|
| Issued by | Deutsche Rentenversicherung | Bundeszentralamt für Steuern (Federal Tax Office) |
| Purpose | Social insurance contributions (pension, health, unemployment) | Income tax identification |
| Format | 12 digits | 11 digits |
| When issued | After first employment in Germany (or after Anmeldung + employer request) | Automatically ~2–4 weeks after Anmeldung |
| Changes? | Never — permanent for life | Never — permanent for life |
| Physical form | Sozialversicherungsausweis (plastic card) | Letter from Finanzamt |
Your payslip (Gehaltsabrechnung) will show both numbers. Your HR department needs both. They are not interchangeable.
How to get your SVNR: first job in Germany
If this is your first job in Germany, you have never been issued an SVNR. Here is how it works:
Step 1 — Start your job and complete Anmeldung first The SVNR application process is triggered by employment. When your employer begins the onboarding process, they will ask for your SVNR. If you don't have one yet, the process is:
Step 2 — Your employer contacts the Einzugsstelle (collecting body) Your health insurer (GKV) acts as the Einzugsstelle for the social insurance system. Your employer notifies them that a new employee without an SVNR has started. The GKV requests an SVNR from Deutsche Rentenversicherung on your behalf.
Step 3 — Deutsche Rentenversicherung issues the number Deutsche Rentenversicherung assigns your SVNR and sends you a Sozialversicherungsausweis — a small plastic card with your name and number — by post, to your registered address (Anmeldung address).
You do not need to take any direct action. The process runs between your employer, your health insurer, and Deutsche Rentenversicherung. Your only role is:
- Have your Anmeldung done (so the card has an address to be sent to)
- Tell HR you don't have an SVNR yet — they will initiate the process
If you want to apply directly: You can also write to Deutsche Rentenversicherung directly if you need to expedite. Include your full name, date and place of birth, address, and a brief note that you have started employment in Germany. Address: Deutsche Rentenversicherung, 10704 Berlin.
How long it takes — and what to do in the meantime
Typical timeline: 2–6 weeks from your start date.
What to do while waiting:
- Tell your employer you are awaiting your SVNR — this is normal and expected for new arrivals
- Your employer can legally start paying you without the SVNR; they use a placeholder and correct the reports retroactively once it arrives
- Your pension contributions are correctly recorded from day one — no contributions are lost during the waiting period
You will not be penalised for the delay. The Sozialversicherungsausweis is sent to your registered address, so make sure your Anmeldung is done before your start date.
