Through hole components on a PCB
Plated through holes, which is what you seem to be referring to, are normal for both vias and through hole pads in modern double-sided or multilayer PCB fabrication.

Typically this fact would be buried somewhere in the specifications of a board service (there will often also be a limit on the maximum hole size which can be plated, and an indication if slots can be plated or not).  Generally a hole surrounded by at least a certain diameter of surface copper will be plated, and one drilled in the absence of a pad or plane will not, but again this falls to the detailed specifications and specific interaction of your software with theirs.

If in doubt, contact the board manufacturer or utilize one with more clearly stated specifications.
