So I emailed the ANA this morning and I asked them about why my member number did not have a letter in front of it. They said the letter is not important and is only used for accounting purposes. Which is kind of odd since every ANA member I see has a letter in front of their number. So I asked them for my letter, and it's BR, short of basic rate.
