From an all-students e-mail:

Non-Emergency Police Number 101

The number for the Non-Emergency Police (Thames Valley) has changed to a new National Number which is 101. The old number 08458 505505 will be discontinued after 31 March 2012. University of Oxford student cards that were issued prior to this notified change in number will display the old number until those cards expire.

Good to see the university letting us know that they can’t remotely edit our plastic cards.
