Is GEP the same as GOLD ELECTROPLATED?

Yes. GEP, GOLD ELECTROPLATED, G.E.P. all denote the same material — gold-plated. Different markets and eras stamp it differently, but the purity is identical.

How do I confirm a GEP stamp is genuine?

Look at the mark under 10× magnification for crisp, even strikes, cross-check the weight-to-volume ratio against the expected density, scan it with the Jewelry Identifier app, and — when it matters — have an XRF test done by an assay office or gemological lab.
