Have a look at an FOI Decision Notice (Holy Trinity Church FS50236990 3 August 2009). It related to a request for residential postcodes of children & staff of a school. ICO decided that the full postcode is PD, but not Outbound code (e.g. LS21). Also, have a look at the House of Lords case CSA v SIC - the key question is whether the individual can be identified by other information in the possession of the data controller. One of the most interesting things is that there is more on "what is personal data?" coming out of the FOIA regime. That is why we cover it in our UPDATE sessions with our colleagues at Pinsent Masons (www.amberhawk.com for details - a non too subtle Xmas marketing message). Merry "whats its" for those still on-line.

Two things: 1) In terms of personal data, the postcodes won't identify any individual addresses although I am aware of an ICO decision notice that said full postcodes did constitute personal data, even where they cover more than one address. 2) We do not inform our students of this use of their data so I am struggling to get past principle 2. Has anyone dealt with a similar request?
