For NO3- (Nitrate ion), we can determine the steric number by counting the number of electron domains around the central N atom. We count both atoms bonded to the Nitrogen atom as well as lone pairs around the atom.
In Nitrate ion, there are three Oxygen (O) atoms bonded to the central Nitrogen. There are no lone pairs (unbonded pairs) of electrons on the Nitrogen. This gives us a Steric Number of three.
A steric number of three, with no lone pairs, means that NO3- will have a trigonal planar molecular geometry.
