I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Or you may try this code to delete all the rows from original sheet if the id's don't exit on the IDList sheet.
Please find the attached workbook where on Original sheet, you may click the button to delete the unwanted rows.

Sub DeleteRows()
Dim lr As Long
Application.ScreenUpdating = False
lr = Cells(Rows.Count, 3).End(xlUp).Row
Range("G4:G" & lr).Formula = "=MATCH(A4,IDList!A:A,0)"
On Error Resume Next
Range("G:G").SpecialCells(xlCellTypeFormulas, 16).EntireRow.Delete
Range("G4:G" & lr).Clear
Application.ScreenUpdating = True
MsgBox "Rows deleted successfully.", vbInformation, "Done!"
End Sub
