Frequently Asked Questions

Registration Basics

Why Register?

  1. Why should I register my 406 MHz emergency beacon?

    Registration is free and can result in a more efficient search and rescue (SAR) effort. The importance of registration is further described in this brochure.
  2. How often do I have to re-register my beacon?

    Registration renewal occurs every 2 years, and NOAA will remind you about this deadline via email or postal letter beginning 2 months before the renewal date. We suggest that you note your renewal date on a calendar and log in to your online registration account near the renewal date. After you log in, you will then see a link to renew your registration(s) on your account home page.
  3. Will I get fined if my beacon is not registered?

    The following is stated in the beacon brochure (see #1):  Beacon registration is required by Federal regulations (Title 47 of the CFR, Parts 80.1061, 87.199, and 95.1402). Failure to register the beacon, or to notify the National Oceanic and Atmospheric Administration (NOAA) of a change in beacon ownership, could result in penalties and/or fines issued to the owner by the Federal Communications Commission.
  4. Can I register my non-US beacon with NOAA?

    You should register your beacon with the national authority associated with the country code in the hex ID of your beacon. See the Cospas-SARSAT Beacon Registration Contact Information web page for a list of national authorities.
  5. Do I need to register my military beacon in both JSETS and the NOAA Beacon Registration Database?

    No. If your beacon is registered in the Join SARSAT Electronic Tracking System (JSETS), it should not be registered in the NOAA Beacon Registration Database.

General Information

  1. How do I register my beacon?

    The easiest way is to register online, and setting up an online user account is the first step in online registration. If you already have a user account, you can register additional beacons under that account.
  2. Where do I register my beacon?

    At NOAA’s 406 MHz Beacon Registration Database website.
  3. What information do I need before I can complete the online registration of my beacon?

    Registration requirements are described here.
  4. How long does it take for my registration to become active?

    Online registrations are active immediately; registrations that are mailed or faxed to NOAA are active within 2 business days of receipt.
  5. Are 23-hex second generation beacons (SGBs) available for sale and use?

    SGBs are not yet authorized for use and cannot be sold in the US. Until they are authorized for use, SGBs WILL NOT GENERATE ALERTS TO SEARCH AND RESCUE FORCES. SGB registrations can be submitted to NOAA, but will not be active until SGBs are authorized for use. If you have purchased an SGB in the US, please contact us.
  6. Can I have more than one beacon registered to a vessel/aircraft?

    Yes, because each beacon has a unique hex ID. You can link multiple beacon registrations under one user account.
  7. Do I need to register my programming dongle/adapter separately from my ELT?

    Yes, your beacon’s hex ID and the hex ID coded in the programming dongle/adapter MUST be registered in your Beacon Registration Database account. This ensures that accurate registration information is available to search and rescue forces even if the programming adapter fails, becomes disconnected, or is removed. Both registrations can be maintained in one user account.
  8. Can I register my organization’s beacons to one account even though different individuals may use them at different times?

    Yes. An organization’s registrations can be linked to one or more user accounts for ease of maintenance.
  9. How do I access multiple beacon registrations from one account?

    You must link the registrations to your user account. RGDB staff can assist with this if you’re unable to do it online. Please contact us and we’ll help!
  10. How do I register a PLB that I use in different ways (boating, hiking, flying)?

    If you use your PLB on a boat or aircraft, complete the registration fields for vessel MMSI #, AIS MMSI #, or aircraft tail number, if applicable. Then use the “Additional Data” section to list hiking/road vehicle routes if using your PLB on land, along with names/locations of the areas you frequent. In “Additional Data” you can also provide identifying information for a boat, such as federal/state registration number, vessel name (e.g., boat name is SEA HUNT), type (e.g., fishing boat, sailboat), colors, and length/capacity. If using on a boat or plane, include your home port/principal airport names and locations (e.g., Sunset Marina, Miami, FL) in Additional Data, as well as your float/flight plans. The information you provide in “Additional Data” is provided to search and rescue forces in the event that your beacon is activated.
  11. How long is my registration information valid in the NOAA registry?

    We request registration renewal every 2 years, but owners can update their information at any time online. Registration records are never completely removed from the database but are marked appropriately if the beacon is labeled out-of-service or was destroyed.
  12. What does it cost to register a beacon?

    Beacon registration is free!
  13. What happens to my NOAA beacon registration if I move out of the USA and take my beacon with me?

    You should get your beacon reprogrammed for the country code in which you will reside, then notify NOAA when you have registered it with the proper national authority. See the Cospas-SARSAT Beacon Registration Contact Information web page for a list of national authorities.
  14. How long does registration last (does it expire)?

    Registration expires every 2 years.
  15. Why do I have to register in the country I live in if the beacon can be used all over the world?

    Beacons must be registered in the country for which they are coded ; it is recommended that owners possess beacons that are coded for the country in which they live (and usually where they use the beacon most).
  16. Where should I place my decal sticker when I receive it?

    Follow the instructions for NOAA registration decal placement that are provided with the decal.
  17. Is there a fine if I accidentally activate my beacon?

    No, but false activations are an issue. Please read our webpage about Preventing False Alerts.

Updating Registrations

  1. How do I update my beacon registration information?

    Once you have created an online user account, the easiest way to update your information is online.
  2. Why should I update my registration information?

    Search and rescue forces use your registration information during rescue operations, so ensuring the accuracy of your registration information is in your best interest in the event of a beacon activation.
  3. Can I update my registration information over the phone?

    Yes, you may call in updates to an existing registration during business hours: 7:00 a.m. until 5:30 p.m. Monday through Friday, except on Government holidays.
Return to top

Renewing Registrations

  1. Now that my beacon is renewed, does that mean it works?

    No. Registration has no effect on a beacon’s working ability; the beacon and its battery must be in good working order for proper function.
  2. Why do I have to renew my registration every two years?

    To ensure that your most current contact information is available to search and rescue forces in the event of an activation.
  3. If my registration is expired, will my beacon still work?

    Your beacon’s operation and registration are completely separate; expired registration information is still available to search and rescue forces in the event of an activation.
  4. How do I request a replacement decal?

    Call or email us to request a replacement decal if yours gets lost or damaged before the renewal date. Note that every time you renew your beacon registration, you will receive a new decal listing the new expiration date.
Return to top

Changes of Ownership

  1. How do I change registration information if I purchased a beacon from someone who had registered it previously with NOAA?

    Beacon registrations are tied to both the beacon ID and the owner/operator. If you buy a second-hand beacon, you will need to register it as though it was new. Our website will alert you to the fact that a beacon has been registered before. You should double-check the ID and if correct, simply ignore the warning. You will be able to submit your registration as “Pending” and the registration database staff will then process the registration. This process can take a few days to complete.
  2. How do I sell or transfer my beacon registration to a new owner?

    If you sell or transfer your beacon to a new owner, you will need to log in to your registration and change the status of it to “Sold/Transferred.” You can also call or email us for help.

Registration Information Requirements


  1. What is a UIN or Hex ID?

    The beacon’s unique identification number (UIN), also known as a hex ID, is a 15- or 23-hexadecimal character string consisting of numbers 0 through 9 and letters A through F. The hex ID uniquely identifies your 406 MHz beacon and is encoded in the message your beacon transmits to search and rescue services if your beacon is activated. When your beacon is activated, satellites will detect the transmission and relay the distress alert to search and rescue services. The hex ID contains the country code and other identification features relative to the carrier, which are dependent upon the coding protocol used. You can find your beacon’s hex ID on a label affixed to the beacon or in the beacon documentation provided by your beacon manufacturer. If you have difficulty locating your beacon ID, contact your beacon manufacturer.
  2. What do I do if my beacon ID is coded with a Maritime Mobile Service Identity (MMSI) number?

    Beacon ID coding using MMSI numbers is not allowed by the US Coast Guard and FCC for 15-hex first generation beacons (FGBs) and cannot be registered in the NOAA database. If your 15-hex FGB is MMSI-coded, contact the manufacturer for help with reprogramming the beacon using an acceptable coding protocol. Second generation (SGB) 23-hex EPIRBs and certain Automatic Identification System (AIS)-equipped PLBs may use a MMSI coding protocol in the US and can be registered in the NOAA database.
  3. What are AIS and MMSI numbers?

    If your EPIRB or PLB is equipped with an Automatic Identification System (AIS) or has a manufacturer-programmed Maritime Mobile Service Identity (MMSI) number that is different from your vessel’s MMSI, enter it in the AIS MMSI # field when registering your beacon. The AIS MMSI # field should start with digits 970, 972, or 974. For more information on MMSI, go to
  4. How can I tell what country code my beacon is coded for?

    Enter your beacon ID in the Cospas-Sarsat 406 MHz Decode Program.
  5. What do I do if my beacon is programmed with a test/orbitography/unsupported beacon ID?

    If your beacon is coded with any of these protocols, you will need to contact the manufacturer for help with reprogramming the beacon using an acceptable coding protocol. A beacon coded with one of these protocols will NOT generate an alert or rescue response.
  6. Where on the beacon can I find my manufacturer label?

    The location of the manufacturer label varies by beacon type and manufacturer.
Return to top

For all beacon types

  1. What information do I need to register?

    Please review the information provided here before beginning the registration process.
  2. Where do I find the beacon ID? What do I do if I can’t find the beacon ID number on my beacon?

    The beacon ID is located on the manufacturer’s sticker, which is on your beacon. If you cannot find the beacon ID, contact the beacon manufacturer.
  3. Are beacon ID, hex ID, and UIN all the same thing?

    Yes. They are all terms that identify the 15- or 23-character hexadecimal unique identification number for your beacon.
  4. What is the checksum and where do I find it? What if I don’t have the checksum?

    The checksum is a 5-character hexadecimal number (consisting of the letters A-F and numbers 0-9) that helps to ensure that the correct beacon ID is recorded. Typically, the checksum (abbreviated as CHK) is only provided on the manufacturer-supplied registration form included in a new beacon’s packaging. If you cannot locate a checksum to enter in your registration, you may leave this field blank and continue with your registration. However, if you leave the field blank, our system cannot further verify that your beacon ID has been entered correctly. If you cannot enter a checksum value, we strongly recommend that you very carefully verify that the beacon ID you entered is correct.
  5. Who should I list as an emergency contact?

    Someone with whom you are in regular contact and who will usually know about your travel plans that include use of a beacon. This person should not be accompanying you on your travels.

Return to top


  1. How does a distress beacon work?

    When a distress beacon is activated, it transmits a signal that can be detected by satellites. As the satellites orbit the earth, they "listen" for any activated beacons and carry the beacon signals to ground stations that compute their positions and report to rescue authorities. For more details, see this SARSAT system overview.
  2. Can I use my PLB for emergencies at home, like if I fall?

    If you are experiencing an emergency in your home, call your local emergency responders to assist you. Only activate your PLB for a home-based emergency as a last resort. Note that PLBs are primarily intended for use in outdoor, off-the-grid environments.
  3. If I go out of the country with my beacon will it still work?

    Yes, if it is in working order with a working battery. Cospas-SARSAT is a world-wide system. Please read this overview for more information.

  1. How can I improve my chances of being found?

    Register your beacon and update your contact information and travel plans online 24/7.
  2. Will I be charged fees for my rescue?

    Every rescue is unique, based on assets used and the outcome, and costs incurred cannot be predicted.
  3. Who pays for someone to come and rescue me?

    Every rescue is unique. Rescue forces have different funding sources which may include reimbursement by the rescued party.
  4. How long will it take for someone to come if I am registered in the U.S. but live in Canada?

    Search and rescue assets are launched from locations near the site of the beacon activation, so the beacon location at activation is the only factor used to determine which SAR forces respond.
  5. How long does it take for SAR forces to respond once my beacon is activated?

    Every rescue is unique, based on the situation. Search and rescue forces work diligently to perform rescues in the timeliest fashion possible.
  6. If my beacon is not registered and it goes off, how long will it take for someone to locate me?

    The Cospas-SARSAT system will still work, but not registering your beacon defeats the purpose of owning a beacon and taking advantage of current technology. When a beacon is not in a national registry, SAR forces may have a more difficult time locating the beacon owner; the satellite system will receive the alert notification, but not any registration information, which can reduce time spent getting to the activation site, potentially saving your life.
  7. Who does the Coast Guard or Air Force contact first when a beacon is activated?

    Usually the beacon owner/operator is contacted first, but every rescue effort is unique.
