As always, spot-on advice.  Thank you David & Jeorg!

For the list's (other similar inquirers') edification, my zip was a string,
so the corrected final example code using dummieslab (SSC) was:  

set seed 1234
sysuse auto, clear
gen zipcode = 21210+ceil(5*runiform())
tostring zipcode, replace

encode zipcode, g(zipcodetemp)
dummieslab zipcodetemp, template(zip_@) novarlabel 
drop zipcodetemp

Ben,

Try -dummieslab- (Philippe Van Kern & Nicholas J. Cox) from SSC.

. rename zipcode zip
. dummieslab zip
