Electronic signature in El Salvador

Updated in September 2023

The validity and regulation of electronic signature in El Salvador is covered by the Electronic Signature Law of 2015. In this law, both the simple electronic signature and the certified electronic signature – known as the advanced electronic signature in Spain – are equated with handwritten signatures. Both have full legal validity.

It is important to note that this law includes the concept of a digital signature, but it refers to cryptographic methods that are more related to PINs used for credit cards than for signing purposes.
