What is the address for 206th St?

• A. 23000 E
• B. 20600 N
• C. 17800 N
• D. 10800 N

Answer: (B)

In this grid system, each block north or south of the central baseline adds one hundred to the street address. So a street labeled with a number in the hundreds corresponds to that many blocks away from the baseline, with a directional letter indicating north or south.

206th Street sits 206 blocks north of the baseline, which translates to the address 20600 with a north indicator. The other options don’t fit: they would place you in different directions or at different block counts (23000 E would be east of the baseline, 17800 N is 178 blocks north, and 10800 N is 108 blocks north). Therefore, the correct mapping for 206th Street is 20600 N.
