The post address of Kyiv ("Kyiv" is an official transliteration; "Kiev" is not used) office is absolutely correct:

Chervonoarmijska 114 - 20

252006 Kyiv, Ukraina

Telephones are correct too, but not the code. I INFORM YOU AGAIN that the telephone code of Ukraina has changed and reads now +380, not +7, so the correct number is:

tel./fax +380-44-2692468, tel. +380-44-2685526

P.S. Excuse me for I couldn't give this information before because I was ill.
