Hello, we are reading a data set in which the variable that identifies the individual is 18 digits long. We have storaged this variable as a double type variable, but the variable is not read correctly. It looks like only 16 digits have been read.

How can we get stata read this variable with 18 digits of accuracy.

The best way is probably to read and store the ID as a string variable of type str18, instead of a numeric variable of type double. You can still sort and merge by a string ID.

I hope this helps.
