In other words, for high longitudes, lower numbers and for lower longitudes high numbers are assigned.  As, NH-2 is located in North Eastern States and NH-68 is located in Rajasthan.

4. If we move from East to West, the numbers used for highways located in the North to South direction increases. For example, if number four is used for a highway located on North South but in a Eastern State, then the number for a highway located on North to South but in a Central State or Western State will always be denoted by more than four.

5. Highways which are denoted by three digit numbers are known as subsidiary highways. For Example, 244, 144, 344 are the branches of National Highway number 44.  In the subsidiary highway number, if the first digit is odd, then the highway is located from East to West and if the first digit is even, it is located from North to South.

6. The sections of the subsidiary highways are denoted by placing a letter, A, B, C or D in the three digit number to ease the identification.
