Creating a Unique ID field in ArcMAP

The other day my friendly coworker, Karen, asked me if I knew how to create a unique id field for a dataset in ArcMAP. I remembered doing this before but I couldn’t remember exactly how since I typically still use ArcINFO TABLES for this process…I know that some of you may find it tragic that I continue to bang away at my keyboard using command line but somethings are still way more efficient that way. So answer Karen’s question I had to consult the mighty ESRI Knowledge Base and as is often the case the question had already been asked.

Basically, you need to add a numeric field and calculate values using the VBA code available at this ESRI Technical Article link

Hopefully this was helpful Karen?

    then use Michelles FID +1 suggestion
    Hope it helps. It helped me use the wonderful Hawths' tools - free arcGIS tools.
