I replaced a 2-prong outlet with a GFCI, wired as shown (connected ground wire coming into the box to the metal box as well as the ground screw of the GFCI, black wire to brass terminal & white to silver). The box has no separate grounding wire and wires are only in Romex, not metal conduit. Multimeter shows hot and neutral are correct. Later, I realized I never checked whether the ground wire was actually grounded at the service box. To be code compliant, do I need to apply the "no equipment ground" sticker regardless, or only if the bare copper wire coming in is not grounded at the service box?

The NEC in 250.130(C) now requires extending an Equipment Ground Conductor to the grounding system when making an extension of a two-wire circuit that does not have an EGC.
If your circuit was extended before the current requirement or was extended by local exception then the receptacle needs to be marked " No Equipment Ground" and the ground should be left disconnected.
