The list of all the Estonian Tax and Customs Board’s X-tee subsystems and services is available in the X-tee services catalogue, where the subsystems created for the Tax and Customs Board’s X-tee as well as their services can be found by the Tax and Customs Board’s registry code (70000349), the name of the institution, the code of the subsystem, or the name of the subsystem or service.
Users with the legal right to represent enterprises and organisations that are registered in the Estonian e-Business Register can join the X-tee through the X-tee Self-Service portal. If you have any questions about joining the X-tee, please contact the Information System Authority (Riigi Infosüsteemi Amet, RIA) customer support at [email protected].
