To do this, I think my local ground control guy (KMIC) has to telephone
the KMSP TRACON for the code. Maybe the call goes to a desk rather than
to a possibly-busy controller where there could be a workload issue?

It depends. Does MIC have a DBRITE? If so then they more than likely
will have something set up with MSP so MIC can get their own codes so a
call doesn't have to be made.




One time out of Ames, IA talking to the Des Moines TRACON I got a local
code (0xxx). When I was leveled out I asked the TRACON controller "Can
you give me a code that will get me to Minneapolis?" Got a "stand by"
and in a couple of minutes he called back and gave me the code. At the
appropriate time he then handed me off to Center, no problem.

He didn't call MSP, he simply input a VFR flight plan into the FDIO
which spit out a center code.
