The +352 2783 prefix is a geographic National Destination Code (NDC) assigned to the Vianden area in the Grand Duchy of Luxembourg.

Dialing Formats
When calling a Vianden number from within Luxembourg, subscribers must dial the national trunk prefix 0 followed by the NDC and the subscriber number. For example, a local call to a Vianden number would be dialed as 0 2783 123456. From abroad, callers must use the international access prefix (typically 00 or +), followed by Luxembourg's country code 352, then the NDC without the leading trunk prefix. Thus, an international caller would dial +352 2783 123456.
It is important to note that Luxembourg uses a closed numbering plan for geographic numbers: the NDC and subscriber number together form a total of 9 digits after the country code. In the case of the 2783 prefix, the subscriber number consists of 5 digits, making the complete national significant number (NSN) 9 digits long.
