SpTH App - Irun - what region / autonomous city?

Ok, so I bail for Spain in a couple of days and I went to fill out the SpTH app for my code and I can't figure out what region / autonomous city Irun is in for filling out my first address (Starting on the Norte), so I can't complete the form. I checked wikipedia, google maps, etc, and none of the options seem right. I very well could be an idiot. Here are the options:

Andalucia
Aragon
Asturias

Balears, Illes

Canarias
Canatabria
Castilla - La Mancha
Castilla y Leon
Cataluna
Ceuta
Comunitat Valencia

Extremadura

Galicia

Madrid
Metilla
Murcia

Navarra

Pais Vasco

Rioja

Idiot?
