This format is similar to the previous one, except that the telephone number has the spaces between the National Number Dial and the remainder of the number have been stripped and have been appended as spaces to the end of the number to keep the length to twelve characters.

4. Other formats
These other distribution methods are also available but they are not available through the web site. Contact the CTPS if you need to order these formats.
It is the responsibility of the CTPS licensee to integrate use of the data file into their everyday working practices.
The way in which they choose to do this is entirely up to the licensee and will not be defined by CTPS or its agents. For example,
those sites which have sophisticated automatic telemarketing systems, may well adopt a different strategy to those with a more modest set-up.
We are unable to offer specific advice on suppression software. Should you need any advice please contact your software supplier.
CD-ROM
For full licenses, Acxiom will provide the CTPS telephone numbers in ASCII variable
comma-delimited format in ISO 9660 format. |
