Send Jose a physical postcard — printed on heavy cardstock and mailed by USPS to the North Dakota State Capitol. State legislators hear from far fewer constituents than Congress does, so a single card carries real weight.

Capitol Mailing Address
State Senator Jose Castaneda
North Dakota State Capitol
Bismarck, ND 58505
Mail to North Dakota legislators is delivered to North Dakota State Capitol in Bismarck, where legislative staff log and route constituent correspondence. State capitols receive a fraction of the mail volume that Congress does, and unlike mail to Washington D.C. it is not irradiated — so a card addressed here arrives faster and competes with far less.
