Eurostat provides bilateral advice to EU Member States when requested on specific cases. This may be before or after the transactions themselves are undertaken. The advice takes the form of letters addressed to the National Statistical Authorities.

In certain cases of future events, where the preparation for the events are of a confidential nature, Eurostat does not publish its advice until the events are announced by the national authority concerned.

Please see also the guidelines for  Eurostat’s ex-ante and ex-post advice (clarifications and decisions) on methodological issues.
