The Order Exposed - Email number code

The Order Exposed is a blog/ alternate reality game based on the happenings of the upcoming PlayStation 4 exclusive The Order: 1886.

So far there have been a few references to old books, and a 'Masonic code' (with key) posted. In fact the first post holds a key too, although less obvious.

In the top left, written on the yello post-it note, is the key to the number code received by sending an email to ian.q1985[at]gmail[dot]com. The automated repsonse reads:

Hello,

I’m travelling and will only have sporadic access to my email. I’ll try to get back to you as soon as I’m able.

Cheers,

Ian

By using the grid on the post-it, the following number can be deciphered to read:

"HOTEL INDIA SIERRA TANGO OSCAR ROMEO YANKEE"

This is NATO phonetic alphabet spelling the word "HISTORY." 

I haven't tried calling the telephone number included as a hot link in the email, but hopefully someone who lives in the United States will do so soon, and post the outcome online.

Now to see if History is a cypher for the code posted on 1 January, or how it relates to the OTP from 2 January. The letter J (or Juliett) is missing from the 5x5 grid in the image above. I'm not sure if this has any implications on the 1 Jan. code though.
