As Tim Williams suggested  using Application VLookup will not throw an error if the lookup value is not found  unlike Application WorksheetFunction VLookup    If you want the lookup to return a default value when it fails to find a match  and to avoid hard-coding the column number -- an equivalent of IFERROR VLOOKUP what  where  COLUMNS where   FALSE   default  in formulas  you could use the following function   Private Function VLookupVBA what As Variant  lookupRng As Range  defaultValue As Variant  As Variant     Dim rv As Variant  rv   Application VLookup what  lookupRng  lookupRng Columns Count  False      If IsError rv  Then         VLookupVBA   defaultValue     Else         VLookupVBA   rv     End If End Function  Public Sub UsageExample       MsgBox VLookupVBA  ValueToFind   ThisWorkbook Sheets  ReferenceSheet   Range  A D     Not found    End Sub
