Incoming address uses 5+4 zip

When the address used as a basis for routing uses a 5+4 digit zip code, the routing steps that handle geographic areas for zones defined using zip/postal codes consider the following possibilities:

• Exact 5+4 digit zip code
• Zip code range using 5+4 digit masks
• Exact 5 digit zip code
• Zip code range using 5 digit masks

When lanes are defined using zones, the hierarchy for geo-precision is as follows (from most to least precise):

• Geographic area entries using 5+4 digit mask with a geo-precision of Exact Postal Code Long Format. In this case, an exact match exists between the "from" zip code in the geographic area table entry and the 5+4 digit zip code for the address.
• Geographic area entries using 5+4 digit masks with a geo-precision of Postal Code Range Long Format. In this case, the 5+4 digit zip code for the address falls in the range defined by the geographic area table entry. If more than one such geographic area entry qualifies, results will be unpredictable.

  For example: If the postal code for the incoming address is 10012-1234, all of the following would qualify:

  • a range of 10012-1000 to 10012-2000
  • a range of 10012-0001 to 10012-5000
  • a range of 10010-0001to 10029-9999

  Routing makes no attempt to evaluate the relative precision of the various ranges. Users are advised to avoid configurations using overlapping ranges.

• Geographic area entries using 5 digit zip mask with a geo-precision of Exact Postal Code (Short Format). In this case, there would be an exact match between the "from" zip code in the geographic areas table entry and the first 5 characters of the zip code for the given address.
• Geographic area entries using 5 digit masks with a geo-precision of Postal Code Range (Short Format) where the geo-precision rule is Postal Code more precise than City. In this case, the 5+4 digit zip code for the address falls in the implied range defined by the geographic area table entry. If more than one such geographic area entry qualifies, results will be unpredictable.

  For example: If the postal code for the address is 10012-1234, all of the following would qualify:

  • a range of 10012 to 10015
  • a range of 10010 to 10020
  • a range of 10000 to 10099

  Routing makes no attempt to evaluate the relative precision of the various ranges. Users are advised to avoid configurations using overlapping ranges.

  When considering ranges that use the short format mask, only the first 5 characters of the postal code for the incoming address will be considered. Otherwise, a postal code of 10012-1234 would not be included by a 5 digit range from 10000 to 10012.

  Note: Zip code ranges less precise than City are only available using the shorter zip code format (5 digit zip codes).

• Geographic area with a geo-precision of City.
• Geographic area with a geo-precision of Postal Code Range (Short Format) where Postal Code is less precise than City. Same considerations as defined for 4 above.
• Geographic area with a geo-precision of Distance Radius.
• Geographic area with a geo-precision of State.
• Geographic area with a geo-precision of Country.
