He's mostly, but not fully correct when talking about the randomness. The first 3 characters match the Dublin postal districts. People living in Dublin 12 start with D12. On one hand, maybe that's useful but on the other hand, it's a way for people to potentially discriminate based on the "good/bad" areas of the city.
If I have to give you D12 as my postal district anyhow, what is the new mechanism for discrimination?
