I bought a book through mail order and the seller sent me an email asking me if the address he had was good and this is my answer

If you could write 750000 instead of 750010 it would be better but don't be afraid it will arrive correctly whatever number you have written

I chose present perfect because I did not know (still don't know) if he had already written the address at the time I wrote my reply. What do you think of my choice , is it a good one

    The most important thing for most learners to know about Perfect verb forms is don't overuse them! In fact, avoid them wherever possible. I think the problem here is that "the rules" defining contexts in which Perfect forms could be used seem reasonably simple, so TELF teachers are too keen to drum those rules into their students, and the students are then excessively keen to actually apply their new-found knowledge about where to use Perfect forms. But in reality, native Anglophones naturally tend to use the simplest verb form possible in any given context (which ain't Perfect! :) Nov 21, 2021 at 16:21

You might say whichever number you write/use. The plain form of the verb works for general statements, and this question doesn't seem to depend on a particular time of use/writing.
Also, if they are asking about the correct address, they probably haven't already sent the book.

  • i don't understand why you said it is a general statement it relies on a particular time (the time before he wrote the address)

  • @user5577 The statement it will arrive correctly whichever number you use is always true, isn't it? There's no need to complicate that with a verb with tense. Nov 21, 2021 at 16:24
