Overall, yes. The eIDAS Regulation specifically concerns electronic signatures within the European Union, ensuring their recognition and legal validity between Member States. However, outside the EU, the validity of eIDAS-compliant electronic signatures depends on national laws.
Many countries have adopted legislation similar to eIDAS, recognizing the legal value of electronic signatures. For example, in the United States, the Electronic Signatures in Global and National Commerce Act (ESIGN) and the Uniform Electronic Transactions Act (UETA) govern the use of electronic signatures.
In practice, it is common for eIDAS-compliant electronic signatures to be accepted and recognised in many countries outside the EU. However, it is always recommended to check local laws and specific requirements to ensure the validity of electronic signatures in the relevant country.
