Step by step on how to verify the legitimacy of A1 Certificate

The A1 or PDA1 certificate shows which national Social Security and Labour Law legislations a worker is subject to, that is, that apply to the worker.  The A1 or PDA1 certificate is issued by the Social Security institution where the worker habitually resides (the sending country).  It is a fundamental document within the context of intra-EU posting or worker mobility within the EU and EEA. 

All workers legally employed in country “A” by a TWA that are temporarily seconded or leased to a client (user undertaking) in country “B” must possess an A1 certificate or prove that it has been requested. Mere proof or request is considered satisfactory (or sufficient) for up to 3 months after the workers have been leased by almost all the Labour Inspection Authorities within the EU and EEA.
