Is there a way to have an EU code?

Unfortunately not, sorry. It could probably be done by grouping certain countries together, but this will take further development and that wouldn’t be available for some time, sorry.

Here’s the list of alpha-2 codes for 51 European countries:

al, ad, am, at, az, by, be, ba, bg, hr, cy, cz, dk, ee, fi, fr, ge, de, gr, hu, is, ie, it, kz, xk, lv, li, lt, lu, mk, mt, md, mc, me, nl, no, pl, pt, ro, ru, sm, rs, sk, si, es, se, ch, tr, ua, gb, va
