"The U.S. State Department Operations Center set up the following number for Americans seeking information about relatives in Haiti: (888) 407-4747. The department cautioned that because of heavy volume, some callers may hear a recording. The State Department said those interested in helping immediately may text 'HAITI' to '90999' and a donation of $10 will be made automatically to the Red Cross for relief efforts. The donation will be charged to your cellphone bill. The department also suggested contacting agencies such as the Red Cross or Mercy Corps to help with relief efforts."
