Question: Can I Call 911 for Someone Having an Emergency in Another State?
Answer: Yes, but as with almost every answer I give you, it's a bit more complicated than it sounds.
Emergency dispatch centers (called public service answering points, or PSAPs) are responsible for tending to the needs of those in their designated areas. These centers are not guaranteed to find a center for you in another part of the country, but that doesn't mean they won't try. Unfortunately, it's not going to be quick. Most centers use the very same tools you do to find phone numbers in other states -- the Internet or telephone companies. What they have that you don't is a working relationship with telephone companies that usually results in better cooperation.
A PSAP may be reluctant to help you if their system is busy when you call. Rightly so, a busy 911 dispatcher is going to take care of the folks in his or her area before trying to help someone hundreds of miles away.
There are some things you can do to help the 911 dispatcher help you:
Know Where the Emergency is Happening
Know the address, including city and state, where the person having the emergency is located. No one can help you if they don't know where to go. Knowing the phone number is a good back-up. If the person is at home, and she is listed in the telephone book, the PSAP will be able to trace the number to an address. If the person is not listed, they still may be able to trace it using a database called the Automatic Number Identification/Automatic Location Identifier (ANI/ALI).
Call 911 From a Cell Phone
PSAPs that answer cell phone calls have more experience tracking down odd locations. It's not unheard of for a cell phone to skip over several cell towers to one in a completely different state.
If you are concerned about a loved one in another state, call the police department in the town where he or she lives and get the 10-digit number (7 digits + area code) to call in case of emergencies. If an emergency arises, call the 10-digit number instead of 911. It will connect you directly to the correct PSAP, and you can give the operator the address so she can send help.
