All possible fractions are contained within the limits of numeric ranges. Individual fractional addresses should not be coded unless they fall outside of the numeric range or have a different ZIP+4 Code. If the range is 1–99(O), 13 1/2, 49 1/3, 57 3/4, and 75 1/16 fall within the limits of the range. 99 1/2 does not, nor does 1/2 or any other purely fractional address.
If a fractional address is the beginning or ending number on the blockface, the ZIP+4 file will show a numeric range record and one or more fractional address records that share the same ZIP+4 Code. The address should be ranged to itself (99 1/2–99 1/2 B). If your fractional address needs to carry a different ZIP+4 Code, it must be pulled out of the numeric range as a separate record.
