You can make a numeric id with

egen g=group(id)

and then you can try adding labels with

ssc inst labutil
labmask g, val(id)

or perhaps

gen numid=real(id)
gen strid=id if mi(numid)
egen g=group(strid)
su numid
replace g=r(max)+g
ssc inst labutil
labmask g, val(id)

to cut down on the label creation.
