A computer-readable device storing instructions that, when executed by a processing device, performs operations comprising:
- receiving geographically-based 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 geographically-based code information based on the zip spanning distance;
- determining at least one neighboring geographical region contiguous with the bounded 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 bounded geographical region of interest using boundary point information of the at least one neighboring geographical region and disseminating discrete epochs of digital content in a digital content distribution platform.
