Aren't postcodes a security risk?

We're pretty hot on security, as you might expect, but we go an extra mile when it comes to postcodes. For example, when we punch in the information from a paper questionnaire, we don't store a young person's whole postcode with the rest of their answers.  We replace the last bit of the postcode (the PF of EX2 8PF) with 99 in the files, so, even if we were hacked and someone found the file, they couldn't use the information to find anyone. We fetch and use the full postcode only when we are drawing maps or doing other analysis by area.
