-3. The sum of oxidation numbers of the atoms in all polyatomic ion is the net charge - its part of the definition of oxidation number.
In any neutral compound, this number must be zero.
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.

No. Not only is it not true, but it it were, there would be no polyatomic ions!
AlI3 The algebraic sum of the oxidation numbers of the combining atoms must equal zero. The oxidation state of Al3+ is balanced by three ions of iodine (I-).
what is the oxidation number for phosphate
The oxidation number of phosphorous as an element by itself is 0. The oxidation number of P in a compound or polyatomic ion will depend on the other atoms it is bonded with. A commonly used period table lists -3, +3, and +5 as the most common oxidation numbers for P in compounds.
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.

Oxidation numbers
The overall oxidation number of an ion is indeed the charge. Na+, sodium is +1 ON, Cl-, chlorine is -1 ON. For a polyatomic ion the charge is the sum of the oxidation numbers of the consituent atoms. For example NH4+ ; N is -3, H is +1 so overall ON is +1 same as the charge.
