Welcome to the website of the IGSN e.V., the Implementation Organization of the International Geo Sample Number (IGSN), a unique identifier for samples and specimens collected from our natural environment.

The objective of the IGSN e.V. is to implement and promote standard methods for locating, identifying, and citing physical samples with confidence by operating an international IGSN registration service with a distributed infrastructure for use by and benefit to its members.
