Untested:
from sets import Set
vvals = Set(a[0] for a in LIST1) # get all the List1 first elt. values
for d in LIST2:
if d['code'] in vvals:
d['VERIFIED'] = 1

I think if list1 is potentially long, the main thing is to avoid n**2
running time, which means use a set or dict to do the lookups, like
above.
