Number

The official release number assigned by the IRS to the written determination for purposes of uniquely identifying it. A common convention in the tax profession is to precede this number with an acronym identifying the type of written determination that has been released by the IRS (e.g., PLR 200834007). But the IRS does not attach any such acronyms to these documents for purposes of assigning the official “Release Number,” so no such information is provided here.
