Dublin has US Customs and Border Protection preclearance, so passengers to the United States clear immigration in Ireland and land domestically. Only a handful of airports outside the Americas have this, and Dublin and Shannon were the first in Europe.
The other code, EIDW
Every airport has two codes. The three-letter IATA code, DUB, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, EIDW, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why EIDW looks nothing like DUB.
