Thousands-Block Reports By Region
Available, assigned and retained thousands-block information by region may be downloaded, by clicking on the links provided in the table below.
Each Blocks Available, Blocks Assigned and Blocks Retained file will be in an Excel file by region. Within the file, each tab will contain a state, and the data will be sorted by NPA, NXX and X.
The combined Blocks Available, Assigned and Retained file, will be in a text (ASCII, comma delimited) file for each region.
There will also be two text (ASCII, comma delimited) files that will contain all regions together. The augmented version will include two additional fields: “Region” and “State”.
