What's the format of the housing dwelling number (box A) in Relevé 31 while claiming for the solidarity tax credit? The 15 numbers on the RL31 I got didn't work.

Sorry I don´t understand and I keep having the same message Box A of your Relevé 31 is incomplete or contains invalid characters. Do not enter the hyphens. How do you put the street name and street number? Or do you just put the number?
