What is the Service ID

[#1]

To do a BT speedtest I need the Service ID of plusnet as well as my telephone number.  What is this information and where can I get it?  I have done a search for "Service ID" here but got nothing useful.

Just the telephone number is required the Service ID is an option.

For some people the ID is needed.

Only if they have SDSL and I'm not sure if BT Speedtester will work with SDSL lines.

Thats not what the speed tester says itself, at one stage it was insistent that I provide an ID as well as a telephone number and told me that I should get this from my ISP, and I have ADSL2+

The test page states

Quote

Please enter your Telephone Number (e.g. 01234123456) Or Service ID Or Both , below then click on "Go" to start the performance test.

I do know my Service ID as it stated in the ticket when I was upgraded from fixed speed ADSL to 21CN WBC as part of the original trial.

Yes, but *sometimes* for *some people* after you enter your telephone number only, it displays an error message saying you need both, I know this because I have had just such an error message.

If it a new telephone number the system probably will as it use the telephone number to look up the Service ID. If it's a new line the database probably will not be up to date.
