How do you get a German social security number in 2026?

Give your employer the personal details and health-insurance information requested for payroll. The employer must electronically retrieve an existing pension insurance number.

If you have never had one, the employer's social-insurance registration can start the assignment. A statutory Krankenkasse, meaning a public health insurance fund, also participates in employment reporting.

Privately insured employees should tell payroll that they have no existing number if that is the case. The employer can initiate assignment rather than asking you to invent or obtain a different identifier.

The Versicherungsnummernachweis is the official insurance-number proof. It replaced the document formerly called the Sozialversicherungsausweis.

Employers normally retrieve the number electronically. You may be asked for the proof only if the automated match cannot identify you clearly.

The number also appears on pension-insurance letters and may appear on payroll or annual social-insurance records. Store the proof securely because it contains personal data.

Do not request a fresh number merely because you changed employer, insurer, address, or surname. Search old payslips and German Pension Insurance correspondence first.

Tell payroll about earlier German employment and any former name. Duplicate records can split contribution histories and should be corrected by Deutsche Rentenversicherung, meaning German Pension Insurance.

If the proof is lost, request a replacement through German Pension Insurance or ask your statutory insurer for guidance. A replacement proof is different from creating a new number.

Employers use the number to report pension, unemployment, health, and long-term care insurance data through payroll. German Pension Insurance uses it to connect contribution periods to your pension record.

It is not the same as the 11-digit tax identification number. Payroll needs both for different systems.

When leaving Germany, keep the number and contribution records. The identifier remains relevant if you later return, claim a German pension, or coordinate insurance periods under international rules.
