Octothorpe
We can distinguish between the name of a symbol (arguably octothorpe) and its pronounciation as 'hash' , 'pound' or 'number sign'. This is analagous to the '&' character which is known as an ambersand but pronounced as 'and'.
Fun fact: ambersand used to be counted as the 27th letter of the English language. We've lost other letters over the centuries too but anyone interested should use their favourite search engine to read the fascinating story of the English Alphabet.
