Which GUID can I use as a placeholder

Question

I have a database table that has an empty type column uniqueidentifier. It has been put in place for use in the near future. But for now, I need to use some kind of placeholder. Can i just use:

00000000-0000-0000-0000-000000000000

for all rows until the real guid is applied, when new rows are inserted in the future? Does SQL Server provide uniqueness in this column?
