How to Get a Social Security Number in Germany
Updated: 4 days ago
Last review: 10 August 2026
Start a job in Germany — or touch its social insurance system in any other way — and one identifier follows you for life: the social security number (Sozialversicherungsnummer). Your employer reports your pay under it, your pension contributions are booked to it, and if you one day leave Germany for good, it is the quickest way to match a pension refund claim to your account. This guide explains what the number is, how to read it, how you get one as an employee, freelancer or student, and how to find a number you already have but can't locate.
What the German social security number is
In German employment paperwork, "social security number" almost always means one specific identifier: the 12-character Versicherungsnummer — eleven digits and one letter — issued through the German pension insurance (Deutsche Rentenversicherung). Employers use it in social insurance reporting, and the pension insurance uses it as the key to the account where every month of your contributions is recorded. It is not one universal number for every branch of the system: your statutory health insurer, for instance, runs its own, separate Krankenversichertennummer.
The same number appears under several names — Sozialversicherungsnummer on hiring forms, Versicherungsnummer or Rentenversicherungsnummer in pension letters, SV-Nummer on payslips — and it is assigned once, for life. A new job, a new city, even leaving the country changes nothing: return to Germany after ten years abroad and your first new payslip carries the same number as your last old one.
How to read the number
Every German social security number follows the same pattern. Take the specimen 13 220483 B 653 — a fictional example whose final digit deliberately fails the statutory checksum, so it cannot be anyone's real number:
Area number (first two digits). The district code of the pension insurance carrier that first assigned the number: 13 stands for the Rheinprovinz district, whose accounts sit with DRV Rheinland today; 04 is Brandenburg; 14 is Oberbayern. The code identifies that carrier — it is not a code from your address registration, and it does not reliably show where you lived or where your insurance history began.
Date of birth (six digits). Day, month, year: 220483 means born on 22 April 1983.
Birth-name initial (the letter). The first letter of your surname at birth — B for Bauer. Marrying or changing your name later doesn't alter it.
Serial number and check digit (last three digits). A two-digit serial number separates people who share a birth date and initial — the ranges also encode how a person is recorded: 00–49 for male insured persons, 50–99 for female insured persons and for people recorded as diverse or without a gender entry. The final digit is a check digit that lets systems catch typos. In the specimen: serial number 65, check digit 3.
Those first two digits gain one practical use later on: they hint at which pension office originally opened your account. What they can and can't tell you — and which office actually decides an international claim — is a chapter of its own: see which German pension office handles your refund claim.
Three numbers it is not
Germany hands every newcomer a small collection of identifiers, and mixing them up costs time:
Tax ID (Steueridentifikationsnummer). Eleven digits, sent to you automatically by post after you first register your address. Payroll tax and child benefit run on this number, not on your social security number.
Tax number (Steuernummer). Issued by your local tax office (Finanzamt) — mainly relevant for freelancers' invoices and tax returns.
Health insurance number (Krankenversichertennummer). Your health insurer's own number, printed on your health card.
None of these can stand in for the social security number: if a form asks for your Sozialversicherungsnummer, only the 12-character number above will do.
Where you'll need it
Expect to be asked for the number wherever employment and social insurance meet. Your employer requests it with your hiring paperwork and reports your employment and contributions under it. The pension insurance books every contribution month to it. The employment agency uses it to identify your record if you ever claim unemployment benefits, and rehabilitation and similar social insurance benefits reference it too. It also appears on every payslip and on the contribution statement (Meldebescheinigung zur Sozialversicherung) your employer must give you once a year — worth keeping, as we'll get to.
How you get the number
There is no application form for most people. The number is created the first time the social insurance system deals with you — what that looks like depends on how you earn.
Employees: it happens automatically
Most employees never apply for anything. When you start a job:
Your employer collects your details — identity, address and health insurance (pick a statutory insurer such as AOK, TK or Barmer, or document private cover). Which supporting documents an employer asks for varies; many want the Anmeldung confirmation from your local registration office. Registering your address is part of settling in anyway — but neither the Anmeldung nor your insurer choice is what creates the number. That happens in the next step.
Your employer registers your employment through the social insurance reporting system — first checking electronically whether a number already exists for you. If none does, this registration is what triggers the assignment by the pension insurance's central data office.
You receive the Versicherungsnummernachweis by post — an official letter stating your number, name and birth name. Since 1 January 2023 this letter has replaced the old Sozialversicherungsausweis; new entrants no longer get a card.
You can start work before the letter arrives — your employer normally has the number electronically before you do. The same goes for any future employer: hand over the number if you have it, or simply say so if you don't; they can retrieve or request it the same way.
Students and interns
Working students get the number the same way as any employee — through the employer's registration. Internships are less intuitive: whether a placement runs through social insurance registration depends on its type, not on pay. A compulsory internship completed in the middle of your studies is insurance-free even when paid; a compulsory internship before or after enrollment is pension-insured even when unpaid, and the company registers it. You don't have to classify your own internship — the employer does that — but it explains why one intern receives a Versicherungsnummernachweis and another doesn't. And even where nothing is registered, a number may already exist for you, assigned for another statutory purpose such as your health insurance. If you're asked for one and can't find any, that's normal and fixable: see the next sections.
Freelancers and the self-employed
Self-employment alone does not trigger an assignment — but don't assume you have no number. Three situations cover almost everyone:
A number already exists. Any earlier German employment — a working-student job, even a mini-job — created one, and other statutory routes such as health insurance can have led to an assignment too. Find it rather than request a new one (see below); the number never changes.
Your work is subject to compulsory pension insurance. The law covers certain self-employed groups. Some — self-employed teachers and coaches, many craftspeople — register with Deutsche Rentenversicherung directly; artists and publicists go through the Künstlersozialkasse, which handles registration and reporting for them. A number is assigned in the process if none exists yet.
Neither applies. Then you generally don't need the number just because you freelance — one is first assigned when the social insurance system has business with you, for example if you opt into voluntary pension contributions or later take up employment.
One frequent mix-up: registering your business with the Finanzamt gets you a tax number, and your Anmeldung triggers the tax ID — neither of those is, or replaces, your social security number.
Where to find your number
Before requesting anything, check the paper you already have — the number is printed in more places than most people expect:
the Versicherungsnummernachweis — or an old Sozialversicherungsausweis: the card was discontinued in 2023, but the number on it is still yours;
any payslip, usually labelled SV-Nummer or Sozialversicherungsnummer;
the annual Meldebescheinigung zur Sozialversicherung from your employer;
any letter from Deutsche Rentenversicherung.
Nothing on paper? Two free routes. Your statutory health insurer has the number on file and can help. Or go to the source: request it — or a new Versicherungsnummernachweis — from Deutsche Rentenversicherung through its online services or in writing, giving your date and place of birth, your birth name and your current postal address. One thing the pension insurance will not do, for data-protection reasons, is read the number out over the phone: it always comes by post. Either way it costs nothing — the pension insurance itself warns that some websites charge a fee for arranging exactly this free document; there is never a reason to pay for it.
Lost your number — or searching from abroad?
A lost number is never a lost account. Your contribution record exists whether or not you can name its number, and Deutsche Rentenversicherung can identify it from your personal data: full name and any former names, date and place of birth, your last German address and your German employers.
The search matters most to people who left Germany years ago and now need the number for a pension refund claim. The same sources apply — old payslips, the annual Meldebescheinigung, any pension insurance letter in a moving box. In a managed claim, we can help identify or recover a missing German pension insurance number; if no number can be found, the claim can still be filed using other identifiers, such as your full name, date of birth and last registered address in Germany. Processing may take longer without the number, and recovery cannot be guaranteed in every case.
Leaving Germany for good?
The number tracks contributions in — and for some people, it later tracks money back out. Depending on your citizenship, where you live after leaving and your contribution history, the employee share of your German pension contributions may be refundable. Our free eligibility check walks through citizenship, residence and the 60-month and 24-month rules — a preliminary indication in under a minute. The result is not an individual legal decision and does not cover every edge case. For the full picture, start with the complete German pension refund guide.
Frequently asked questions
Is the Sozialversicherungsnummer the same as the Rentenversicherungsnummer?
Yes. Sozialversicherungsnummer, Rentenversicherungsnummer, Versicherungsnummer and the payslip abbreviation SV-Nummer all refer to the same 12-character number. Only the tax ID, the tax number and your health insurer's Krankenversichertennummer are genuinely different numbers.
Do I need the number before my first day of work?
No. Your employer can register you without it — the number is assigned or retrieved electronically during that registration, and the confirmation letter follows by post. Starting a job is how most people get the number in the first place.
Can I apply for it online?
For most people there is nothing to apply for: the number is created automatically with the first job. What you can do — online and free of charge — is request your number or a replacement Versicherungsnummernachweis from Deutsche Rentenversicherung, or simply ask your health insurer. Be wary of websites that charge for this: the document is always free from the pension insurance itself.
How long does it take to arrive?
Deutsche Rentenversicherung publishes no fixed delivery period — the letter simply follows your employer's registration by post. Your job does not have to wait for it: employers normally retrieve the number electronically. If you need the number and the letter hasn't come, ask your payroll department first (they often already have it), then your health insurer — or request it from the pension insurance online or in writing.
What happens if I lose it?
Nothing dramatic: the number never expires and never changes, so any document that shows it — an old payslip included — restores it, and a replacement Versicherungsnummernachweis is free from Deutsche Rentenversicherung or via your health insurer. Do treat the number as identity data, though: it belongs on official paperwork, not in casual emails.
I'm abroad and can't find my number — can I still claim a pension refund?
A missing number does not by itself prevent a refund claim from being filed — sufficient personal and employment information is still required, and identifying the account can take longer. Check old payslips and employer certificates first; beyond that, the pension insurance can locate your account from your personal data, and in a managed claim we can help recover the number. Whether you qualify for a refund at all is a separate question, covered in the complete guide above.
Next step
If Germany is your new home, you now know everything the number will ask of you — keep the Versicherungsnummernachweis with your documents and the rest takes care of itself. If you are leaving or have already left, check whether your contributions are refundable: the eligibility check gives a preliminary indication in under a minute, and the complete guide covers the rules in depth. You may apply directly to Deutsche Rentenversicherung without using our service; the pension office charges no application fee.
