Greek Phone Books, Phone Codes and Phone Directories
Finding a Greek phone number is free online, and there are several free residential and business phone directories in English. The country calling code of Greece is 30, and every regular Greek telephone number (area code + subscriber number) has ten digits. There are currently two-, three-, and four-digit geographical area codes, so the length of the subscriber’s number varies. The only two-digit Greek phone code is 21 for the Athens. To make an international call from Greece dial 00 + country code and number.
Free telephone number search
The Hellenic Telecommunications Organization S.A., usually known by its Greek initials OTE, is the former monopoly and still the biggest telecommunications player in Greece. They’re the best way to find a listed residential or business phone number.
The OTE White Pages
(http://www.whitepages.gr/en/) is the free official OTE “11.888″ white pages for people and businesses in Greece. You can do a reverse search with the full ten digit telephone number.
The Greek Yellow Pages
(http://www.xo.gr/default.aspx?la=2) are the Greek yellow pages in English (or just choose language link on top right of the search page). The site has been “beta” for ages. but it’s still effective at finding phone numbers!

I have tried to use the above link, but its crazy its all in greek….where do you find a site in english???
Thank you
Hi Maria,
They appear to have a new beta site which as far as I can see doesn’t have an English version. The boxes at the top are where you put in your queries:
WHO? (name or phone number)
eg Sotiris Valvanis or 2106116255
WHERE? (district, county, route)
eg Kallithea, Attica, Arcadia 5
If you use the Google Chrome browser, it will offer to translate it for you and the results are quite good, the navigation is clear. The new URL is actually:
http://11888.ote.gr/web/guest/home
Give it a try!
