Deductions & credits

The IRS says:

The IRS will void the ITIN and associate all prior tax information filed under the ITIN with the SSN.  Send your letter to: 

     Internal Revenue Service 
     Austin, TX [removed]

 

Is the above address correct? It doesn't have P.O. Box number? Will above written address enough for USPS to deliver my mail to IRS ?

 

Thanks a lot in advance.
