I am building on a 12 x 24 foot addition and it was recommended I pour a 6 inch deep 3 foot wide footing under the outside walls and build a "pony wall" on top of it. Will that be deep enough or wide enough for code?

Footing sizes are determined by the load (building) on top of them, and the type of soil. The depth of the footing is determined by how deep your frost line is. The top of the footing is to be placed below the frost line. A 3 foot wide footing is not standard - 20 to 24 inches wide is standard. If 3 feet wide is recommended, it is probably due to shifting or expansive soil conditions at your location. Six inches thick is the minimum allowed by code, and is probably ok for a one story addition, but I don't know enough about your soil type to say yes or no.
Check with your local code enforcement officer / building inspector. You need good information for this - if you screw up the footing, everything built on top of it will also be screwed up.

The six inch deep measurement is simply the thickness of the footing itself, the bottom of the footing should be set at approx. 48" in climates which freeze in the winter and thaw in the summer.

it varies with location; sometimes even from city to county. your local building inspector can give you specs and rebar requirements.
