Easily Locating the Serial Number on Your AED: A Guide to Finding the Unique Identifier for Your Device

Where to Find Your AED Serial Number

The serial number on an AED can typically be found on a sticker at the back of the device. This sticker is usually located at the top, on one of the corners, or on the side of the AED. The label is marked with “SN” followed by a series of letters and numbers, and a barcode is usually located below it.

Philips AEDs

The serial number on a Philips AED is located on the back of the device next to the battery well.

HeartSine AEDs

The serial number on HeartSine Samaritan PAD (350P, 360P, 450P) AEDs is located on the right side of the underside of the device.

Defibtech AEDs

The serial number on Defibtech defibrillators is located at the upper back of the device. For the Defibtech Lifeline DCF-100, the serial number is located just below the handle. You may need to remove the spare electrode pad bag from the pocket to uncover it.

Cardiac Science AEDs

The Cardiac Science Powerheart G5 has a large sticker on the upper back of the device with the serial number, expiration date, and other important information.

Physio-Control AEDs

The serial number on the Physio-Control LIFEPAK CR2 is on the large sticker at the bottom of the underside, under the battery well.


The ZOLL AED 3 has the serial number sticker on the back, just above the battery well. Be sure not to confuse it with the barcode sticker on the battery pack itself.

Format of AED Serial Numbers

The format of a serial number varies among manufacturers. For instance, Philips HeartStart OnSite serial numbers begin with the letter “A”, while Philips HeartStart FRx serial numbers start with “B”. These serial numbers then consist of 8 characters, such as “BXXX-XXXXX”. On the other hand, HeartSine Samaritan PAD serial numbers consist of 10 to 11 digits, including 2 numbers, a letter, and further numbers. The first 2 digits indicate the year of production.

Obtaining Additional Information About Your AED

Obtaining Additional Information About Your AED

To receive further information about your AED, you can reach out to the manufacturer’s website. You may need to fill out a contact form or send an email with the serial number and your purchase details. When communicating with the manufacturer, make sure to include the relevant information about your device.

Enroll Your AED with Emergency Medical Services

Whichever brand you have, you should also register your serial number and the AED’s location with your local emergency medical system. The state of New Hampshire, for example, has a website and matching app where you can register your AED.

Cardiac arrest statistics show that rapid defibrillation is one of the best ways to improve survival rates, and you never know when there might be a sudden cardiac arrest near you. If the rescuers can locate your external defibrillator, it could help them treat an SCA victim in time.

Maintaining Your External Defibrillator’s Updates

Additionally, while searching for the serial number, don’t forget to check the expiry dates of the battery and electrode pads. Parts that are past their expiry date can render the AED ineffective. The frequency of replacement for batteries and electrode pads varies between brands, with a range of two to five years. Some brands offer these parts separately, while others come in a package.

To ensure your AED is always ready to use in an emergency, register your AED with the manufacturer, sign up for the vendor’s battery and pad replacement reminder service, and consider AED program management for facilities that have or manage several defibrillators at a time. Your up-to-date external defibrillator could save a life.
