How do we say the address in English?

73, Fith Avenue. ?

[poli]

No comma needed, otherwise you are correct. The number comes before the the street name except in rare cases.

Poli is right regarding the US Postal Service recommended format. If the address includes an apartment number, unit number or suite number within the building it appears on the same line right after the building's address.

If there's a unit number, an apartment number or a suite number, it appears on the same line as the street. No punctuation is used.
