The AHV/AVS number (Alters- und Hinterlassenenversicherung / Assurance-vieillesse et survivants) is Switzerland's 13-digit social security number, used for pension contributions, disability insurance, unemployment insurance, and all social security interactions. It is assigned automatically by the cantonal Ausgleichskasse (Compensation Office) when your employer registers your employment or when you register at the Gemeinde. This guide explains how the AHV/AVS number is assigned, the contribution rates (5.3% for employee and 5.3% for employer), how to access your AHV account, and your entitlements under the Swiss pension system as a foreign resident.
