The main post offices are situated in Fira, Emporio, and Oia. Here, you will be able to mail letters and buy stamps and postcards. Mailboxes are located in all major holiday resorts and they are always yellow with a blue sign. The service is run by a company called ELTA, which is the name you will find outside every post office in blue and yellow colours.
