It’s not a proton donor, so it’s not a Bronsted-Lowry acid. It is a Lewis Acid, but this is a bit of a digression

Sorry I meant to say is it not a base because it’s accepting protons?

Yeah, at A level you use the Bronsted-Lowry definition for both acids and bases. Therefore acids must donate protons and bases must accept them. NO2^+ does neither, so it’s neither an acid nor a base as far as A level is concerned

But how does no2+ become h2no3+ if it is not accepting protons?

It forms a dative bond to the oxygen in the water molecule - not to a H^+.
