write unique values column pandas

So I have a dataframe with different data:

Ordernumber Name customerID
Abel 1939184849
Rose 1029480129
Rob 1283949203

As you can see the name and customerID are already filled in. Now I need to generate unique ordernumbers, please keep in mind that the actual database has around 20,000 rows, so the ordernumber has to be unique.

Can it be only numbers? i.e. ranging from 0 to the total length of your dataframe?

df['Ordernumber'] = [n for n in range(0,len(df),1)]
