This can't be answered without knowing the voltage, and ground is not the same as neutral, in AC circuits, which I'm assuming this is.

On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
Yes, they are the same size wire.
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.

A 200 amp service panel will require a # 4 bare copper ground wire.
3/0
Service wire required is AWG # 3/0 copper.
Minimum size grounding conductor for a 200 amp service entrance is #6 bare copper.
AWG # 3/0 copper.
A ground wire for a service distribution has to be copper. A #6 copper conductor can be used up to a 200 amp service.
As a service entrance wire you need AWG # 3/0 gauge copper.
200 amp service in chicago uses 3 aught.

4/0 is only rated at 185 amps. You will need 250 MCM wire rated at least 75C, preferred 90C for a 200 amp service.
