For some carriers the remote areas are specified in a CSV file. The first line of the file is ignored. Columns are separated by comma (,). Each line describes the remote area fee for a single post code (or city), or for a range of post codes. Comma is only allowed as a column separator, it is not allowed in the fee name, post codes or city name.
| Column (#) | Meaning |
|---|---|
| A (1) | Country code, 2 letters, uppercase |
| B (2) | Fee name (currently not used) |
| C (3) | Post code, or start post code, or city name |
| D (4) | End post code |
If D is empty then C contains a single post code. If D isn't empty then C contains the first post code in the range, and D contains the last post code.
