A radio ID number is a unique identifier assigned to your vehicle’s radio or infotainment system. It is often required for unlocking a locked radio, activating SiriusXM subscriptions, or retrieving the radio security code after a battery disconnect.
This guide will explain what a radio ID number is, why you may need it, and how to locate it quickly on various Honda models. With this information, you can access your radio functions and services without unnecessary delays.
What Is a Radio ID Number?
A radio ID number is a unique code assigned to your Honda’s radio or infotainment system. It serves as an identifier for the unit, separate from other vehicle numbers.
Difference Between Radio ID, Serial Number, and ESN
Radio ID:
Used for SiriusXM activation, unlocking the radio, or retrieving the security code. It is often displayed on-screen or requested during service activation.
Serial Number:

ESN (Electronic Serial Number):
rimarily used for mobile or satellite systems, such as SiriusXM or OnStar, to register the device.
Where Radio ID Numbers Are Commonly Used

Understanding the difference between these numbers helps ensure you use the correct one for the task at hand, avoiding delays or errors.
How to Find My Radio ID Number by Radio Type
The method for locating your radio ID number depends on the type of radio you have—car, SiriusXM, or home/portable.
Car Radio
- Turn the ignition to ON or ACC so the radio powers up.
- Access the radio display menus and navigate to Settings, System Info, or Radio Info—depending on your model.
- On some older Honda radios, you may need to use a preset button combination (e.g., holding Preset 1 + 6) to display the ID. Check your owner’s manual if this method is required.
SiriusXM Radio
- Tune the radio to Channel 0.
- The radio ID number will appear on the screen.
- Record the ID exactly as displayed, as it is required for subscription activation or troubleshooting.
Home or Portable Radio
- Check the back, bottom, or inside battery compartment for a label containing the radio ID.
- Some models allow you to view the ID via the settings or information menu on the device.
By following these steps, you can quickly locate your radio ID number for activation, unlocking, or service purposes.
How to Find Radio ID Number Without Turning On the Radio
If your radio is not powering on or you prefer not to turn it on, there are alternative ways to locate the radio ID number.
Check the Radio Unit Label
Many Honda radios have a label on the back, bottom, or side of the unit that displays the radio ID, serial number, and other identifying information. Removing the radio may be necessary for some models.
Owner’s Manual or Purchase Receipt
Some vehicles include the radio ID number on a sticker in the owner’s manual, on a radio code card, or printed on the original purchase receipt.
Vehicle Service Records
Authorized Honda service centers often record the radio ID during maintenance or battery replacement. Reviewing your service records or contacting the dealership can help retrieve the number without powering on the radio.
These methods are especially useful if the radio is disabled, the battery is disconnected, or the display is not working.
How to Find Radio ID Number by Brand
The process for finding a radio ID number can vary depending on the vehicle or radio brand. Here’s a guide for common brands:
Honda, Toyota, Ford, Chevrolet

- Toyota: Turn the radio ON, press and hold Preset 1 + 6, or check Settings → System Info.
- Ford: Access the Menu → Settings → Radio Info while the ignition is ON.
- Chevrolet: Turn the ignition ON, press and hold Preset 1 + 6 or check Menu → Info → Radio ID.
Pioneer, Kenwood, Sony (Aftermarket Radios)

SiriusXM-Compatible Radios
- Tune to Channel 0 on your SiriusXM radio.
- The radio ID will appear on-screen.

By following these brand-specific instructions, you can locate your radio ID quickly and accurately for activation, unlocking, or service purposes.
What to Do If You Can’t Find Your Radio ID Number
If you’re unable to locate your radio ID number using the display, labels, or manuals, there are still ways to retrieve it.
Removing the Radio from the Dashboard
- On some vehicles, the radio ID is printed on a label on the back or side of the unit.
- Carefully remove the radio according to your vehicle’s instructions to access this label.
- Note: Removing the radio may require special tools, so consult your owner’s manual or a professional if unsure.
Contacting the Manufacturer or Dealer
- Provide your radio serial number or vehicle information to your dealer or manufacturer.
- They can supply the radio ID remotely or guide you through retrieving it safely.
Using the Vehicle Identification Number (VIN)
- Some dealerships can locate the radio ID using your VIN, especially for factory-installed car radios.
- This method is often the easiest if the radio cannot be powered on or the label is missing.
By using these methods, you can retrieve your radio ID even if the display or documentation is unavailable, ensuring you can unlock the radio or activate services like SiriusXM.
Common Problems and Troubleshooting
Even when following the proper steps, you may encounter issues locating or using your radio ID. Here’s how to address common problems:
Display Not Showing ID Number
- Ensure the ignition is ON and the radio has power.
- Navigate to the correct menu, such as Settings → System Info → Radio ID, depending on your vehicle or radio model.
- On older radios, try holding down preset buttons (commonly 1 + 6) while powering the radio on.
Radio Stuck on “LOCKED” or “CODE”
- This usually occurs if the wrong security code has been entered multiple times.
- Wait for the lockout period (typically 1 hour) before trying again.
- Make sure you have the correct radio code or ID before reattempting.
Faded or Unreadable Labels
- Labels on the radio unit can wear over time, making the ID or serial number difficult to read.
- If this happens, try checking vehicle documentation, purchase receipts, or service records.
- Contact your dealer or manufacturer; providing the VIN can help them retrieve the correct ID.
By following these troubleshooting tips, you can usually resolve common radio ID issues without needing to replace the unit.
Tips to Save Your Radio ID Number
Keeping your radio ID number safe and accessible can save time and frustration in the future. Here are some simple ways to do it:
Take a Photo of the Label
Snap a clear photo of the radio ID label on your unit. This ensures you have a backup if the physical label fades or becomes unreadable.
Store Digitally or in Cloud Notes
Save the radio ID in a secure digital location, such as a notes app, password manager, or cloud storage. This way, it’s accessible from anywhere and won’t be lost.
Write It in the Owner’s Manual
Keep a physical copy by writing the radio ID in your owner’s manual or on the radio code card. This keeps it with the vehicle and easy to reference when needed.
By combining these methods, you can ensure your radio ID is always available when you need it for unlocking, activation, or service purposes.
Frequently Asked Questions (FAQ)
Is the radio ID number the same as the serial number?
No. The radio ID is used for activation, unlocking, or subscription purposes, while the serial number identifies the physical radio hardware. They are separate identifiers and serve different functions.
Can two radios have the same ID?
No. Each radio ID is unique to the specific radio or infotainment unit. This ensures security and prevents conflicts when activating subscriptions or retrieving radio codes.
Do I need the radio ID for every subscription or unlock?
Yes. The radio ID is required for SiriusXM activations, unlocking your radio after a battery disconnect, or recovering a security code. Once used for a subscription, you generally don’t need it again unless the radio is reset or moved to a different vehicle.
Conclusion
Finding your Honda or aftermarket radio ID number is essential for unlocking your radio, activating subscriptions, or retrieving security codes. Depending on your radio type, you can locate the ID using the display menus, preset buttons, SiriusXM channel 0, labels on the unit, or vehicle documentation. If the ID is not readily available, contacting a dealer or manufacturer with your VIN or radio serial number is a reliable option.
To avoid future frustration, always save your radio ID in multiple places—take a photo of the label, store it digitally, or write it in the owner’s manual. Keeping it accessible ensures quick access whenever you need it, whether for service, subscription activation, or restoring your radio after a battery disconnect.
