Are you addressing me, sir?

The String of nonsense lines after a street address lines isn't so meaningless as it seems!

There are three parts to this number: The Belt, the Range, and the Section.

The BELT is the general north/south location. Remember, a belt goes round your waist, and a belt goes round the earth. The border between the U.S.A. and Canada is B1. Going North, the Belt number is always supplied with an "N" before it. ("Bn2" is in Canada, B2 is in the U.S.)

The RANGE is the general east/west location. San Francisco, CA in the westernmost boundary of Range 1, and the numbers get larger as one goes eastward. West of San Francisco, the Range Numbers always have a "W" before them. (Rw1 is Angel Island, R1 is Nobb Hill.)

The Section used Alphabet and numerals to further pinpoint the location. Beginning at the northwest, the east/west is expressed in letters, all of which are used except "I" and "O", to prevent confusion reading. North/south is expressed in numerals 1-24.



This code was adopted roughly the same time the muggle ZIP code was introduced. It was designed to let long-distance postal carriers find the general area quickly.
