The naming conventions for the CallingAreaInfo product delivery file, as well as the naming conventions of individual product files, will change in the 2023.11 release. Field names and data will not change.
The naming convention of the delivery file will change from CallingAreaInfo_<YYYY>_<MM>.zip (where <YYYY> and <MM> indicate the product vintage month and year, respectively) to CALLINGAREAINFO_<GEOGRAPHY>_<VERSION>_<FORMAT>.zip. Follow this link for additional information.
Differences between the current and previous versions of key files in CallingAreaInfo will be tabulated in an Excel workbook named callingareainfo_statistics.xlsx. The CallingAreaInfo_ReleaseNotes_YYYYMM.xlsx workbook previously included in the delivery file will be retired.
Individual file name changes are shown in the following tables.
