Recent Change to New SESAR Namespaces

July 2014. IGSNs are going to change syntax from a 3 digit namespace to a 5 digit namespace, starting with IE (For IEDA, Integrated Earth Data Applications, the facility that oversees SESAR). This change will accommodate the expansion of IGSN, through the IGSN e.V., to more allocating agents around the world.


A new user will still choose a 3-digit alphanumeric namespace, for example ABC, and their IGSNs will be of the form: IEABC0001, where the first 5 digits are the full namespace and the last 4 digits are alphanumeric. This will give users 36^4 possible IGSNs, or over 1.5 million IGSNs.


This change will not affect existing IGSNs or namespaces, but will change all namespaces and IGSNs allocated by SESAR in the future.
