The RateCenterInfo database is divided into three file sets. Each file set can cover the entire United States or Canada. The files are named according to the conventions described below:
United States
| File Name | Table Name |
| rcd_usa.* | US Area Code and Prefix Data |
| rcg_usa.* | US Rate Center Boundaries |
| rcp_usa.* | US Rate Center Points |
Canada
| File Name | Table Name |
| rcd_can.* | Canadian Area Code and Prefix Data |
| rcg_can.* | Canadian Rate Center Boundaries |
| rcp_can.* | Canadian Rate Center Points |
Area Code and Prefix Data tables (rcd_usa.*, rcd_can.*)
The Area Code and Prefix Data tables contain information about the NPA/NXX combinations in each rate center. Communications Suite products now incorporate NPA/NXXs with LERG effective dates (planned changes) through the end of the release month. This ensures that our clients have the most recent data when they receive the product.
Rate Center Boundaries tables (rcg_usa.*, rcg_can.*)
The Rate Center Boundaries tables contain rate center ID information.
Rate Center Points tables (rcp_usa.*, rcp_can.*)
The Rate Center Points tables contain rate center point information.
