What do the letters on the one dollar bill mean?

Question

On the one dollar bill, there is the black circle with a letter on it, and around it it says "Federal Reserve Bank Of" and then it lists the city. For example:

B: New York, New York
K: Dallas, Texas
D: Cleveland, Ohio
G: Chicago, Illinois
L: San Franciso, California

But what do the letters mean? There is also another letter more to the left beside a number, and sometimes it is the same number sometimes different, like it will have C1, G2, A2 and so on.
