Change or not field focus after autofill next fields

There is a form with following fields in following order:

Zip City State Phone

When user enter zip code fields city and state got auto populated based on zip code user entered.

The question is it a good idea to move field focus from zip to phone field after autocomplete happened or no? Basically user enter zip code, next fields got autopopulated and the focus already on phone field. So less actions from user.

Is there any examples how similar functionality done in other websites?
