zinc reacts with acids as in:
Zn+H2SO4-ZnSO4+H2
zinc also reacts with bases as in:
Zn+2NaOH - Na2ZnO2+H2
Therefore zinc should be amphoteric metal.
But none of the sites states that zinc is amphoteric

What is an Amphoteric substance?
Amphoteric Substance is one that can react as either an acid or base."Partly one and partly the other; neither acid nor alkaline; neutral" (I don't think this answer is correct)The word is derived from the Greek prefix ampho- meaning "both".Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides. Other examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water and ammonia.
Is ammonia an amphoteric substance?
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
What are the amphoteric elements?
zinc,aluminum,beryllium and lead.
What are amphoteric metals?
Amphoteric is a chemical entity (ion or molecule) which can react as an acid but also as a base. Compounds of beryllium, tin, aluminium, lead, zinc have amphoteric hydroxides and oxides.
Is sulfuric acid amphoteric substance?
No. It is only an acid.
What is a common amphoteric substance?
Water is an amphoteric substance.
Is a bicarbonate ion an amphoteric substance?
amphoteric

Is zinc oxide an acid anhydride?
No. Zinc oxide is a amphoteric oxide.
Is ammonia an amphoteric substance?
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
Is magnesium oxide amphoteric?
No, only aluminum oxide, lead oxide and zinc oxide are amphoteric oxides.
What are the amphoteric elements?
zinc,aluminum,beryllium and lead.
Can an amphoteric compound act like an acid and a base?
Am amphoteric substance can react as a base but also as an acid.
What are amphoteric metals?
Amphoteric is a chemical entity (ion or molecule) which can react as an acid but also as a base. Compounds of beryllium, tin, aluminium, lead, zinc have amphoteric hydroxides and oxides.
Is sulfuric acid amphoteric substance?
No. It is only an acid.
Which elements form amphoteric oxide?
Aluminium, Silicon, Zinc, Iron, and many more
What is a reagent to show that an oxide is amphoteric?
two of the reagents are aluminum hydroxide and zinc hydroxide.
