If you have receptacles protected on the load side of an upstream GFCI, are they allowed to be 3 prong or must they be 2 prong?

I was on a service call to repair inspectors punch list. This was not pointed out but I did swap the 3 pin with a 2 being that it was not connected to EGC.

Code say anything specifically about this?

The code does not require the receptacles to be 2 prong if they are protected by a GFCI. If you install 3 prong receptacles then you must use the stickers that come in the box that states--"No Equipment Ground" and put them on the receptacle plate

Actually, the code says that the receptacles, not the covers, must be identified.

The requirement, per code, is that a two prong receptacle supplied by a GFCI be marked "GFCI Protected" and "No Equipment Ground".

I understand the requirement, as covers are often lost or put on different receptacles, but it's real tough to get all that writing on the receptacle unless you do it on the back.

Actually that is not what it says, 406.4(D)(2)(b)and(c) allows two prong receptacles to be replaced with three prong receptacles (grounding type) where the replacements are GFCI type receptacles or, where the three prong receptacles are protected by an upstream GFCI, these three prong receptacles (GFCI or regular) will need to be identified as having "No Equipment Ground".

Two prong receptacles obviously have "No Equipment Ground". ;)

The OP's profile says he is under the 2008 NEC. So, Dielectricunion, crack open your NEC to 406.3(D)(3)(c). This 2008 Code passage describes what you found as Code compliant (as to the absence of the equipment grounding conductor connected to the grounding type GFCI protected receptacles). Your change from grounding type to two-wire nongrounding type receptacle, leaving the GFCI in service doesn't create a problem, unless the installation was an extension of old ungrounded wiring, and the extension was installed AFTER grounding type receptacles were required for new installations. I suspect that by installing the nongrounding receptacles, you actually turned the installation into something it wasn't originally allowed to be.

Oops...

I meant three prong receptacles.
 
I forget if its copper or Leviton, but one of them includes GFCI protected outlet and No equipment ground stickers..the other includes GFCI Protected in English and Spanish..I'm sorry if I offend but don't you think GFCI and NO EQUIPMENT GROUND are more important than GFCI in English and Spanish?

I'm surprised that they don't have French labels.

That would be for use in Canada. :)
I got a good laugh out of an English language paperback book labeled "Hecho en Canada"
If the downstream receptacles are required to be TR, you are not likely to find any that are two prong.
