Immigration: Peterborough

Volume 488: debated on Monday 23 February 2009

To ask the Secretary of State for the Home Department pursuant to the answer of 27 January 2009, Official Report, column 283W, on deportation: Peterborough, what fixed datasets are used by the case information database to identify (a) individual names, (b) individual postal addresses and (c) other data; and if she will make a statement. (253646)

[holding answer 3 February 2009]: The case information database uses datasets covering people’s biometric and biographical data to uniquely establish individual identity and a table of addresses using the post office address finder software, table of address links to specific individuals and a further table which describe why the link is in place. These tables help to check that address data are accurate and up to date as possible and reduce the likelihood of errors throughout the individual journey in the immigration process including deportation information.

The case information database stores multiple addresses against an applicant for a variety of different uses including correspondence, prison, place of abode, etc. These are then stored either in elements including house name, street name, county etc. or in one block if the address can not be verified against the post office finder software.

Information on any other data needs to be specific to aid response.
