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

For an employee, the employer reports the hire through its Ausgleichskasse or caisse de compensation, meaning social insurance compensation office. Give payroll your exact passport name, date of birth, nationality, address, and any existing Swiss number. The office can retrieve the record or arrange assignment if you have never had one.

A self-employed newcomer must ask a compensation office to assess the activity. Swiss social insurance looks at the economic facts, including independence and business risk, rather than accepting a contract label automatically. A non-employed resident who must contribute and is not already affiliated registers with the compensation office for the canton, meaning one of Switzerland's 26 regional governments, where they live.

The number appears on the Swiss health-insurance card and on the personal AHV/AVS insurance certificate. It may also appear on payroll or social-insurance correspondence. If neither document is available, contact the compensation office rather than applying repeatedly.

The official InfoRegister can show which compensation offices hold an individual account once you enter the number and date of birth. An individual account is the social-insurance record of reported earnings, contribution periods, and certain credits. It is not a cash pension balance.

For a spelling, birth-date, or identity error, send supporting civil or identity documents to the office maintaining the record. If a card or certificate is lost, request replacement evidence. Do not seek a second number, because duplicate records can separate contribution history.

The number is personal. A spouse or child does not share the worker's number. A child can receive one through health insurance or a benefits process, but having a number does not mean the child has paid contributions or built an adult pension record.

People working across borders, posted by a foreign employer, or active in several countries must first establish which country's social security law applies. EU/EFTA means the European Union and European Free Trade Association coordination route; bilateral agreements can also govern assignments outside that area. Obtain the applicable-coverage decision before assuming Swiss payroll should create contributions merely because a Swiss number exists.
