Importing Accounts - what to do w/ the required Account ID field?

I want to import some Accounts.  On the map fields page, I noticed the Account ID field is required.  Since I'm not migrating from a different CRM, I don't have existing Account ID fields....just the Account Name.  Do I make make up Account IDs for each Account record I want to import?
