The particle へ (he) is used for direction and is pronounced "é" it can be used in several contexts.

We can indicate a movement thanks to the formulation place + へ + verb of displacement: わたし ぱんや へ いきます (I'm going to the bakery)

But also we will indicate a recipient with name + へ: Dupont へ (for Mr. Dupont)

This particle looks like the particle に the difference between the two is that へ emphasizes the travel when に is more for the final destination, this being said in general they are interchangeable.
