My address contains a block number and a lot number, usually written as Block ## Lot ##. This was not accepted in the online application form (VIDEX) of the German Embassy. Their format is also very different. What do I do? :(
Basically fill it out as best as you can in such a way that all data is present and do not be too concerned on how it is split up. For example, the Dubai instructions list a "Villa 21" as House number -- clearly it can be something else than just a number.
This is just an implementation detail and insignificant at that. There's no legal requirement for a Schengen visa to provide a detailed address. For example, this French form for the Schengen visas has a field for the home address and that's it.
