Ouch! Sorry, but the dictionary was more immediately accessible than my copy of the Act. However, from the Act: 1. - (1) In this Act, unless the context otherwise requires- : <snip> "data subject" means an individual who is the subject of personal data; "personal data" means data which relate to a living individual who can be identified.....from those data Lots of reference to "individual" here (although the Act doesn't define "individual", so I hope you will forgive me if I rely on the dictionary for that). I return to my point - landline number may not identify a single individual, it can be shared by several individuals.

Then details of an individuals relationship with their partner can be freely discussed and passed on to others as such information does not belong to one individual because there are two people in the relationship. I would argue that bot come under the banner of personal/sensitive. In a legal context I don't think the Collins dictionary is the final word and to suggest so is very naive. >>> "Cashmore, Stuart" <[log in to unmask]> 06/21/04 10:42am >>> Michael Lord wrote "It is just as valid to call it a personal detail as a landline phone number at home." My partner and I live at the same address, so her landline number is the same as mine. Which of us is it personal to? "Personal (adjective) - belonging to, or for the sole use of, a particular individual" (Collins Compact English Dictionary) "personal" cannot belong to more than one person!

The mobile phone number may be a series of numbers but it does identify a number of things. However, it does not identify a handset. It can be used to identify a SIM card but both the SIM and the phone number may be registered to an individual (in the case of a contract mobile it is always registered to an idividual). In cases where the number is registered there will be details held, on one or more databases, of personal/sensitive data for the individual to whom it is registered. When calling a network for assisstance they will always ask for your number as it is their means of identifying you. It is just as valid to call it a personal detail as a landline phone number at home. >>> Tim Trent <[log in to unmask]> 06/21/04 09:51am >>> I have a different view on phone numbers from that on email addresses. A mobile phone number is simply a collection of numbers. Unlike (eg) a National Identity number is it not, of itself, capable of identifying anything except a phone handset or SIM card. It is thus not personal data. However one is capable of arguing that a mobile phone number, since it is a personal attribute, is capable *with other information* of identifying a living individual in the same manner as a photograph. Thus the context of storage and retrieval of the mobile phone number, in my view, creates scenarios where it may be able to be construed as personal data. It differs from an email address since an email address leads "always" to a person and not to a computer.

So What About a Mobile Phone Number? The discussion about whether or not an email address constitutes personal data or not, is very interesting. So what about a mobile phone number, whether or not one's own personal mobile phone number or a mobile phone number given to an employee by the respective employer?? May one argue on the same lines??
