I am putting new 100 amp service to my garage. Do I use only 100 amp meter socket or can I use a 125 amp

I take it your garage is getting a completely separate service from the utility then? Who is your utility, for that matter?– ThreePhaseEelCommented Feb 22, 2019 at 12:26

As your power utility if they have a list of approved meter sockets, that may eliminate a choice.– TysonCommented Feb 22, 2019 at 13:52

There is no reason why you cannot install a larger meter base than the one required. Keep in mind that equipment is rated to handle maximum currents not minimum. In your case a 100A meter base can only handle current up to 100A. Whereas a 125A handles up to 125A and will handle a 100A current without a problem.
Her's an idea. When I was working we always installed a 200A meter base since know you have the ability to upgrade a service if needed later, and comparing material cost the upgrade was minimal and labor is more or less the same. The only reason we would install a smaller base would be because of space restrictions.
Good luck

In our area, the utility has an approved list of meter sockets. Currently the smallest on the list is 200amp, and it gets a 200 amp drop.– TysonCommented Feb 22, 2019 at 13:51

I agree with 3phase, but as Tyson said many utilities have a minimum and for new services they usually provide a web site with the utility requirements that may be much different than the NEC requirements.+– Ed BealCommented Feb 22, 2019 at 14:23
