You should put Swab John Doe on the address on the envelope. I think it would be delivered without it, but the cadre might possibly use that as a reason to call your swab out. Not necessarily, but they could.Do you have to put Swab John Doe when you write a letter or can you just put John Doe? Confused and I sent a bunch of addresses to people that I just put first and last name without swab. Wondering if I need to change that.
