As of 2015, you can reach Poison Control in the United States by dialing 1-800-222-1222 from any telephone. The center is open 24 hours per day and assists with poison emergencies.
Poison Control operates a large network of centers around the United States, but individuals use a single telephone number to reach them. When calling, the system automatically routes users to a local poison control specialist. The system bases its routing on the phone's area code and exchange. If the individual is calling from a cell phone, the system may automatically route the call to the center that serves the phone's area code rather than the local area.
