A computer-readable device storing instructions that, when executed by a processing device, performs operations comprising:
- receiving zip code information associated with a bounded geographical region of interest;
- receiving a zip spanning distance related to the bounded geographical region of interest;
- determining longitude information values and latitude information values associated with coordinate boundary values of a portion of the zip code information based on the zip spanning distance;
- determining at least one neighboring geographical region contiguous with the geographical region of interest using the longitude and latitude information values;
- and
- creating a zip span polygon region that includes at least a portion of an initial zip span region associated with the geographical region of interest in order to disseminate the discrete epochs of the digital content in a digital content distribution platform.
