What Is an A1 Certificate for Spain?

An A1 Certificate (Portable Document A1) is official EU documentation confirming which country's social security legislation applies to individuals working temporarily in another EU member state. Under EU Regulation 883/2004 and its implementing regulation 987/2009, the A1 Certificate prevents dual social security contributions and ensures continuous coverage during Spanish assignments. The certificate is issued by the competent social security institution in the worker's home country and must be recognized by Spanish authorities. A1 Certificates are mandatory for posted workers, business travelers, cross-border commuters, and multi-state employees working in Spain. The document specifies coverage period, applicable legislation, and worker identification details. For comprehensive information, visit the European Commission social security coordination website or your home country's social security institution.
