Postal Code


Postal Code represents the code generated by the government to facilitate mail delivery.

There is a maximum of 11 alphanumeric characters in acceptable formats.


While Postal Code can be used for destination selection this is usually not recommended, except in the case of refined address resolution. For example, when the same address exists twice with a city, a postal code selection may narrow down which address is preferred.

When displaying an address, the system may also want to display the postal code.


  • Postal Code is assigned to each side of a segment.

  • In areas with the highest coverage level, if a coastline or country border, where the adjacent country is not built yet, defines the boundary duplicate, the known Postal Code is reflected on both sides.

  • Communities served by P.O. boxes still have the appropriate Postal Code applied to the segments. For example, Carmel-by-the-Sea only has P.O. Boxes and no addresses, but carries the Postal Code for the P.O. Boxes.

  • Postal Codes in Europe are not always coded to the most detailed postal level.

  • In some countries, Postal Codes only refer to a few houses, so coding the full Postal Code would require splitting existing segments to create very small segments.
