Shipping in greece?

I want to order some accessories directly from apple.com and ship them to greece. I know that the official distributor if apple in greece is isquare but there are some things that u cant find. Anyway, when i put my postcode it actually says it is expected to arrive in 4 days. But this doesn't make sense to me because its an us store. So, does this actually work? Im just afraid that my postal code matches another’s area postcode and ill send it wrong
