GN 00904.056 Interoffice Correspondence
   
   
   
   All correspondence, claims material, or requests for development of claims material
      will be transmitted directly from one DO to another. When writing on specific claims
      or claims questions, discuss claims on only one social security number in a single
      communication. If claims involving more than one social security number are involved,
      forward with the original a carbon copy of the communication for each additional social
      security number discussed.
   
   
   In order that material forwarded to another office may be readily identified and related
      files found, insert in the subject of the correspondence, the WE's name and social
      security number as well as the names of the beneficiaries involved.
   
   
   When processing center development requests, DO requests for assistance or other items
      of controlled correspondence are being transferred to another office, send an SSA-5006
      (Transfer of Request) to the initiating office on the same day the transfer takes
      place.
