Registering you 406 MHz Personal Locator Beacon:

When you purchase a 406 MHz Personal Locator Beacon, you must fill out a registration form and forward it to the appropriate agency - in the U.S., it's the National Oceanic and Atmospheric Administration (NOAA). On the form, you provide the make, model, and 15-character unique identification number (UIN) of your 406 MHz Personal Locator Beacon, your name, address, phone number, and primary and alternate 24-hour emergency contact phone numbers. You can also include travel / use plans, number of persons onboard, any significant medical information or other information that may assist rescuers in the event of an emergency.
This information is entered into a database accessible at the Mission Control Center, so that if your 406 MHz Personal Locator Beacon is ever activated, your information will immediately pop up on a computer screen at the MCC. Personnel will then attempt to contact the registered owner / user of record and the designated emergency contacts to establish that your distress signal is genuine (and not a false-alarm), and to verify everything they can about the owner / user's intended travel / area of use plan, whereabouts and possible situation. This information will then be passed on to the appropriate search-and-rescue agency.
Residents of the United States may now register their 406 MHz Personal Locator Beacon online, and may also access and amend their registration information and intended travel / area of use plan at any time. The site is http://www.beaconregistration.noaa.gov/. This NOAA website is only open to US citizens, US citizens living abroad, and alien residents currently living in the US with a valid US address. Once a 406 MHz Personal Locator Beacon is registered the information is valid worldwide.
NOAA recommends registration of a 406 MHz Personal Locator Beacon in the country of residence and / or country where the designated emergency contacts reside to avoid a potential language barrier problem.
It must be noted that all 406 MHz Personal Locator Beacon must be electronically coded for the country in which the devise is to be registered. All EPIRBs, 406 MHz Personal Locator Beacons sold by OceanMedix.com LLC are default programmed and coded for registration in the United States with NOAA.
