i have a string variable of 18 lenght. This is my id and i need it

that stata does not maintain the original number. It approx each
variable and in this way i cannot get a unique id Per individual. Do
you know whether it is a problem of wrong format?


It is not a problem of the wrong format.  At the command line type:

    help data_types

and examine the precision of Stata's numerical data types.

I'm curious as to why you believe that you must store eighteen-character IDs as
numbers.  If you need to obtain a numerical ID for use of one of Stata's -xt-
commands, then you can use -encode-.
