Fraudulent emails

Updated on 17 Apr 2026

Emails are currently circulating which claim to be from the Federal Social Insurance Office, in which the sender asks the recipient to provide their OASI (Swiss social security) number so that the FSIO can proceed with a review of their case file.

Finances of the income compensation system (IC)

The FSIO regularly publishes financial projections for the income compensation system and uses the latest available information for these projections. The financial projections are always subject to a degree of uncertainty because they are based on many assumptions about future developments.

Please consult the German, French or Italian version of this page for detailed documentation and further information.
