Behördenbrief (RSa/RSb)

Behördenbriefe (RSa/RSb) Varianten

The right to send official letters (RSa/RSb) is reserved to public authorities only. Such letters must meet the specifications defined in the Austrian Delivery Act and the Delivery Form Regulation. Austrian Post's production standards will apply to the design and production of official letters with advice of receipt (machine-processable letter with advice of receipt, hybrid letter with advice of receipt) For more information, see the download section below.

The following types exist:

  • Letters with advice of receipt delivered to the addressee in person (RSa letter, blue letter)
    These letters will be delivered to the addressee in person only or to somebody who has an auhorization to receive mail on the addressee's behalf. Use the additional instruction "Nicht an Postbevollmächtige" to exclude the latter option.
  • Letters with advice of receipt (RSb letters, white letters)
    Such items may also be delivered to an alternate addressee (people living in the same household, employers or employees of the addressee).

What is the hybrid letter with advice of receipt and how does it work?
For the hybrid letter with advice of receipt, clients send us electronic notification data ahead of time. At the time of delivery, we will send you an electronic proof of delivery as well as ongoing status information.
