Where is this milk from?

In the USA, milk usually has a "plant code" or "plant ID" which indicates what dairy it came from (or where it was packaged).

It is often found next to the used by date, or somewhere on the back label.

If a USA milk does not have one, then I think this means you can assume the milk was packaged locally (e.g. for a farmer's market).
