How to Find Your Car Radio ID

AvatarByMatthew Yates Car & Vehicle Radios

To find your car’s SiriusXM Radio ID, select the satellite-radio source and tune to channel 0; on most compatible radios, the ID appears on the display. If it doesn’t, try the radio’s menu or the dedicated buttons on some older Sirius receivers. First, make sure you need a satellite-radio ID rather than the anti-theft code used to unlock a stereo.

What a Car Radio ID Identifies

A SiriusXM Radio ID identifies the satellite receiver used for your subscription. You may also see it labeled ESN or SID, especially on older radios or account forms.

A satellite-radio ID identifies the receiver; it does not unlock the stereo.

Your VIN identifies the vehicle, not the receiver, although SiriusXM accepts it for some account-verification tasks.

How to Find Your Car’s SiriusXM Radio ID

Use the screen or form asking for the number to decide which identifier you need before searching through the radio’s controls.

What You’re Trying to Do Identifier You Need Where to Start
Activate or manage satellite radio SiriusXM Radio ID, sometimes labeled ESN or SID Satellite-radio display or menu
Unlock a stereo showing a security-code prompt Anti-theft radio code Vehicle paperwork or the vehicle manufacturer’s retrieval process
Identify the stereo for service or parts Radio model and hardware serial number System information, purchase paperwork, or manufacturer support
Register a streaming-only SiriusXM subscription SiriusXM account number SiriusXM account assistance

Step 1: Select the Satellite-Radio Source

  1. Park the vehicle before working through its audio menus.
  2. Turn on the stereo using the vehicle’s normal audio or accessory controls.
  3. Select the satellite-radio source for your system.

You need the satellite-radio source, not AM, FM, Bluetooth, or a phone app. If your car has both a built-in satellite receiver and SiriusXM streaming through a connected phone, use the built-in receiver’s controls.

If there is no satellite option, confirm whether a satellite receiver is installed before continuing. A stereo that can support an optional satellite tuner does not necessarily have that tuner connected.

Step 2: Tune to the ID Channel

  1. Use the tuning control to select channel 0.
  2. Look for an identifier labeled Radio ID, ESN, or SID.
  3. Leave the identifier on the screen while you record it.

Use manual tuning or direct entry rather than relying only on presets or the seek buttons. Presets take you to saved channels, and seeking may not land on the identification screen.

If the identifier appears, you do not need to search additional menus.

Step 3: Try the Radio Menu or Dedicated Buttons

Only use these alternatives if the tuning method did not display the ID.

  1. Open the satellite radio’s menu and look for an item labeled Radio ID, ESN, SID, or an information screen containing that identifier. Exact menu names vary.
  2. On some Sirius radios, press and hold the SAT or ESN button to display the ID, according to SiriusXM.
  3. If the satellite-radio menu and any applicable SAT or ESN button shortcut fail, check the vehicle owner’s manual or installed radio’s manual for instructions on displaying the Radio ID.

The SAT and ESN shortcuts apply to some Sirius receivers, not every car stereo. Confirm which button applies to your model rather than holding unrelated buttons or trying undocumented service-menu combinations.

Step 4: Copy and Check the Identifier

  1. Write down the complete ID or take a clear photo of the display.
  2. Preserve every character, including any leading zeros.
  3. Check the format against the type of receiver installed.
  4. Compare your saved copy with the display, then return the radio to your preferred listening source.

For a receiver identified as Sirius, the usual ID is a 12-digit number. For a receiver identified as XM, the usual ID is an 8-character combination of numbers and letters. Confirm whether your installed receiver is identified as Sirius or XM on its display or in its documentation before using those formats to judge the number.

If any character is unclear, inspect the display or enlarge your photo rather than guessing.

The label beside the identifier matters, too. A number of the expected length is not enough if the screen identifies it as a software version, device serial number, or something other than the satellite Radio ID.

If Your Car Won’t Display a Radio ID

Satellite Radio Is Missing From the Source List

Check the installed audio system’s equipment information or manual to confirm whether a satellite receiver is installed. If a receiver is present but its source cannot be selected, ask the vehicle manufacturer, radio manufacturer, or installer how to access it.

The Car Has a Replacement Radio

Use the ID from the receiver currently installed, not an old record for the car.

An old trial letter, saved photograph, or account entry may identify a receiver that has since been replaced. This is especially relevant with used vehicles and aftermarket stereos.

Some aftermarket systems use a separate satellite tuner connected to the head unit. In that arrangement, the stereo’s chassis serial number is not a substitute for the satellite tuner’s Radio ID. Look for the separate satellite tuner’s Radio ID, ESN, or SID on the installed system’s satellite-radio display or in the tuner’s documentation.

The Menus Still Don’t Show an Identifier

Search the installed stereo’s manual for Radio ID, ESN, or SID to find instructions for displaying the satellite receiver’s identifier.

If the documented method still fails, contact SiriusXM or the radio manufacturer with the vehicle’s make, model, year, and the installed audio system’s name. Describe what appears when you select satellite radio and whether an ID-related menu is available.

Do not remove dashboard trim simply because the first display method failed. Confirm whether the identifier can be retrieved through the controls or account-verification process before considering access to a physical label.

Use the Radio ID for SiriusXM Account Access

Vehicle Radio Subscriptions

The SiriusXM account-verification form accepts the radio identifier, an account number, or a VIN. Enter the identifier you have in the designated field, then complete the other requested account details.

A Radio ID is an identifier, not a password. Providing it helps SiriusXM locate or verify the relevant account; you still need to complete the sign-in or registration prompts.

If you cannot retrieve the ID from the stereo but have your account number or VIN, you can use one of those accepted alternatives for verification.

Streaming Subscriptions

For a streaming subscription, use Need Help? on the verification page to chat with an agent and request your account number. Enter that account number on the form to complete registration.

Do not search the car’s Bluetooth settings or phone device information for a satellite Radio ID when the subscription is streaming-only. The account number is the identifier SiriusXM directs streaming subscribers to obtain.

Confirm and Save the Correct Radio ID

Before submitting the identifier, check that:

  • The display clearly identified it.
  • You entered it in the radio-identifier field, not a password or unlock-code field.

If the form rejects an accurately copied ID, the problem may involve the account details rather than the identifier itself. Confirm the other requested information instead of repeatedly changing characters that match the display.

Save the ID with your vehicle records and label it with the car and receiver it belongs to. If verification still fails, use SiriusXM’s account-help chat with the saved identifier and the error message ready.

Frequently Asked Questions

How Do I Find the Radio ID on GMC Infotainment or a 2016 Chevrolet Colorado?

If the installed system includes satellite radio, select SiriusXM and tune to channel 0 to display its ID. Use the tuning knob or direct-entry control available on that unit; the touchscreen layout depends on the installed infotainment system. Copy the displayed Radio ID rather than a hardware serial number from a general system-information screen.

How Do I Find the Radio ID in a 2021 Ford XTR?

Select the satellite-radio source, open its menu, and look for an entry labeled Radio ID or ESN. Check the installed infotainment system’s manual for the controls used to select satellite radio and display the Radio ID or ESN. Record the complete identifier before leaving the screen.

How Do I Get the Radio ID for a 2009 Subaru Forester?

Use the controls for the installed satellite receiver, which may differ from the stereo originally supplied with the vehicle. Select its satellite source, open the menu, and look for the Radio ID or ESN; copy the identifier exactly when it appears.
