"Someone of Company" or "Someone from Company" [closed]

Which one is correct to say?

1. "Hi, it's Jack of HP Inc"
2. "Hi, it's Jack from HP Inc"

Solution 1:

The fact that you used the third person indicates this is a phone conversation. If you were speaking face-to-face then you would say, ""Hi, I'm Jack ..."

In my judgement you would say, "Hi, It's Jack from HP Inc" to indicate where you are calling from. You can think of it as saying ""Hi, It's jack [calling] from HP Inc"

If you use "of" then it implies to me that you are not calling from your workplace.

However, in the end, it's more a matter of style than grammar. If forced to make an unequivocal choice, I would favour "from".

Let's see what other opinions there are.

Solution 2:

Both correct. In a phone conversation I might assume the first meant Jack works for HP but may be calling from somewhere else than HP. In the second I would suspect he was calling from an office of HP. But I would not be sure of either.
