This will ensure that you at least know when the tickets are going on sale.
The telephone numbers to call (for all test grounds, just one number) is as follows, but make sure you do whatever dingbat code you have to put in first.
The ECB have a general ticket hotline for all international matches.
Call the ECB Ticketline on +44 (0)8705 338833 (calls charged at national rate) for information on all npower Tests, NatWest Series and NatWest International Twenty20 matches.
