If you want to receive your letters digitally at both residences, we recommend the Family tariff. The Single rate includes digitization of letter mail for 1 recipient (read more in this article: What counts as one recipient?).
In this case, you are considered to have two recipients. One recipient is defined as one private person at one residence.
Alternatively, it is of course possible to book two Single rates. Please note that you will need to register two different CAYA accounts for this. You will also need two different e-mail addresses.
The Single tariffs are only valid for one recipient. In the Family tariff you can add up to 5 recipients as defined.
