THE DOCUMENT LOCATOR NUMBER (DLN) AND THE IMF

 

 

 

 

     If you will take a look at your IMF, you will very possibly see a lot of document locator numbers. Documents are identified with a Taxpayer Identification Number (TIN) and they have a Document Locator Number "DLN." The DLN is a part of the Automatic Data Processing System (ADP).

 

     The Document Identification Number is a fourteen-digit number. Every document that enters in the IRS system is classified with a DLN. The DLN tells exactly what the document is and identifies the location and origin of the document as well as the date it was prepared and the individual who prepared it.

 

     The fourteen digits are coded as follows:

 

     a.  The first two digits consist of the filing location code. Generally, this is the Service Center or the district office.

 

     b.  The third digit is the tax class.

 

     c.  The fourth and fifth digits are document codes.

 

     d.  The sixth, seventh and eighth digits are the control or Julian dates. These are calendar dates based upon the Julian Calendar.

 

     e.  The ninth, tenth and eleventh digits are the block number.

 

     f.  The twelfth and thirteenth digits are the document serial

numbers.

 

     g.  The fourteenth digit is the processing year.

 

     Anyway, for those of you who have your IMF, now you know something about what it means.  Good luck.
