Thanks for all the suggestions.

The context of the problem is to build a panel from yearly data using firm names as the unique id with the -merge- command.

Nick/Daniel:
I had thought of  -encode- and -egen-'s-group()- but my panel is unbalanced and I presume both of these are based on an alphabetical sort order? 

Brendan: I think your solutions may prove more useful although am not sure how to turn it into an id to use with -merge-

best
