They don’t know my last name so would it show up somehow on their phone? Thanks:)
It depends on the other ends caller ID. Other Cellphones usually dont pick up names, but my parents land line caller ID gets my full name.
Are you calling someone with a the same phone company ( AT&T to AT&T ) ?
If you are than it is the answer would be maybe. You can block you ID by using *67 before dialing the phone.
If you haven’t blocked your caller I D, they usually can tell.
