How to Find Your Radio ID

For most SiriusXM radios, tune to Ch. 0 to display the Radio ID; a DMR Radio ID is issued by email after registration instead. The term can also mean a two-way-radio unit number, an anti-theft radio code, or a broadcast station’s on-air identification, so identifying the service first prevents a lot of wrong turns.

What a Radio ID Is

A Radio ID is an identifier associated with a radio, user, or subscription. What it identifies depends on the kind of radio you have:

SiriusXM Radio ID: A number used to activate, manage, transfer, or refresh a SiriusXM subscription. SiriusXM may also call it an ESN or RID.
DMR Radio ID: A unique number assigned to a DMR user and tied to that user’s callsign in DMR networks.
Two-way-radio unit ID: A number or label programmed into a business, public-safety, or private radio system so dispatchers and other radios can identify a unit.
Radio code: Usually an anti-theft unlock code for a car stereo after battery replacement or radio removal.
Station ID: The spoken or recorded name, call sign, frequency, or slogan a broadcast station uses on air.

Start by identifying the service, because “Radio ID” is a different kind of identifier in satellite radio and DMR.

How to Find Your SiriusXM Radio ID

Choose a starting point based on the equipment and task:

What You Have	Best Starting Point	What You Are Looking For
SiriusXM in a vehicle or home radio	Use the satellite-radio source and try the ID channel	Radio ID, ESN, or RID
A vehicle whose SiriusXM screen does not show an ID on the channel display	Use the vehicle’s SiriusXM menu path	Radio ID in a settings or subscription screen
A DMR handheld or mobile radio	Register for a DMR ID first	An assigned user ID
A car stereo asking for a security code	Use vehicle-specific ownership documentation or support	Anti-theft radio code

Step 1: Switch to the SiriusXM Source

Turn on the vehicle or radio.
Select the source labeled SiriusXM, Sirius, XM, SAT, or SatRadio.
Confirm that you are not on AM, FM, Bluetooth, USB, or another audio source.

The Radio ID appears when you use the satellite-radio interface.

Step 2: Tune to the SiriusXM ID Channel

Use the preset, channel keypad, tuning control, or channel list to select Ch. 0.
Wait for the channel screen to load.
Write down or photograph the Radio ID exactly as it appears.

For most SiriusXM radios, Ch. 0 displays the Radio ID. It may instead be labeled ESN or RID on different screens.

Some factory radio interfaces use a menu instead of the channel display. Vehicle menu paths differ by make and infotainment system; these common examples show where the Radio ID appears.

On an Aston Martin, press MENU > Sirius Menu > Advanced Settings to display the Radio ID.

On compatible BMW radios from 2003 to the present, enter Sirius mode and hold SAT for more than 3 seconds if your interface has that button behavior. On BMW systems with an Options screen, enter Sirius mode, scroll right to Options, then select Manage Subscription; that interface is listed for 2004 to present BMW models.

In a Ferrari, select SAT mode, then open MENU > Settings to display the audio Radio ID.

For most Mazda vehicles made before 2014, hold the ESN button for approximately 1.5 seconds if the radio has one. In a Mazda3, select Sirius or SiriusXM and tune to Ch. 0; the display shows a 12-digit Radio ID. On select Mazda Connect systems from 2014 or later, select XM , open the channel list, and choose channel 0; the system displays an 8-digit ID.

For Volvo model years 2007 through 2009, press MENU > Sirius Settings > Sirius ID.

Vehicle interfaces vary even within the same brand. For other makes, look in SiriusXM, subscription, service, or settings menus for the Radio ID.

Step 4: Use the ID to Access the Correct SiriusXM Account

Once you have the number, use it when activating service, transferring service to another vehicle, or managing a subscription. The SiriusXM account page accepts a Radio ID, Account Number, or VIN to start account lookup.

Before submitting anything, compare every character with the radio screen.

How to Get a DMR Radio ID

A DMR Radio ID is not normally found by pressing buttons on a newly purchased radio. It is assigned to the user after registration and is then programmed into the radio’s DMR settings.

Register with RadioID.net and request an ID using accurate user and callsign information.
Wait for the assigned ID email. It usually arrives within 24 hours.
Open the radio’s programming software or onboard programming menu.
Enter the assigned ID in the radio’s DMR or digital-radio ID field.
Save or write the configuration to the radio.
Read the configuration back from the radio, if the software supports it, and confirm that the stored number matches the assigned number.

Use the same assigned user ID in every DMR radio you operate rather than requesting a separate personal ID for every handheld or mobile radio. Operate only one radio at a time. Do not copy an ID from another radio, a screenshot, or an online contact list.

If you plan to transmit on DMR, use the rules that apply to your radio service.

Radio ID, Radio Code, and Station ID

A SiriusXM Radio ID, DMR or unit ID, anti-theft code, and station ID each serve a different purpose.

SiriusXM Radio ID

A SiriusXM Radio ID identifies a SiriusXM-capable receiver. It is used for subscription tasks, including activation and account management. SiriusXM may label it Radio ID, ESN, or RID.

DMR or Two-Way-Radio Unit ID

A DMR ID identifies a user on a digital radio network.

The correct ID comes from the system administrator or the DMR registration process.

Car Radio Anti-Theft Code

A radio code is an unlock code for a vehicle stereo. It may be requested after the battery is disconnected, the stereo loses power, or the head unit is removed.

Do not enter random code combinations repeatedly. Find the code through the vehicle owner’s materials, the manufacturer’s support process, or a dealer that can verify ownership.

Broadcast Station ID

A station ID is the short announcement that tells listeners which station they are hearing.

When the ID Does Not Appear

Check the selected source and the vehicle’s menu before treating a missing ID as a radio fault.

Make Sure You Are in Satellite Mode

If the display shows FM frequencies, Bluetooth tracks, or a media-player screen, you are in the wrong source. Select the satellite-radio source before looking for the ID.

Use the Interface That Matches the Vehicle

A channel lookup works on many SiriusXM radios, but some factory systems place the ID in a subscription, service, advanced-settings, or Sirius-settings screen. BMW is a good example: one interface uses a SAT-button hold, while another uses Options > Manage Subscription.

Separate the Account Details

If you are trying to sign in and the Radio ID is unavailable, SiriusXM account lookup can also begin with the account number or the vehicle VIN. That is useful when the radio screen is hard to access or the vehicle has changed.

Avoid Removing the Radio Just for an ID Lookup

The ID is normally available through the radio display or infotainment menus.

If the screen itself is unresponsive, use the vehicle manufacturer’s support route rather than trying to disassemble the radio for a number that should be available through the system or account records.

Confirm and Keep Your Radio ID

Once you find or receive the ID, make it usable later.

Copy it exactly as displayed or issued, including every digit.
Label the note clearly.
Keep a private record with the vehicle or radio model it belongs to.
For a SiriusXM ID, confirm that it locates the intended subscription or receiver in the account process.
For a DMR ID, confirm that the radio’s saved configuration matches the assigned number.
Do not confuse a Radio ID with an account password, VIN, or anti-theft code.

The next practical step is to use the ID only for its intended system: subscription management for SiriusXM, radio programming for DMR, or network identification for a managed two-way-radio system.

Frequently Asked Questions

Where do I find my SiriusXM Radio ID?

For most SiriusXM radios, select the satellite-radio source and tune to Ch. 0 to display the Radio ID, ESN, or RID. If it does not appear, use the vehicle’s SiriusXM menu; for example, some systems place it under subscription, service, or advanced settings.

How do I get a DMR Radio ID?

Register for an ID through RadioID.net, then wait for the assignment email, which usually arrives within 24 hours. Program the issued number into the DMR ID field in your radio and save the configuration.

What is a radio unit ID example code?

A radio unit ID is a system-specific identifier, not a universal code that can be copied. A display label such as “Unit 12” is an example of a unit name, while the actual DMR or network ID is a separate assigned number.

How do I find out what my radio code is?

A car radio code is usually an anti-theft unlock code, not a Radio ID. Check the vehicle’s ownership documents or use the manufacturer or dealer’s verified support process; avoid guessing codes because repeated wrong entries can lock the radio.

Can you give me an example of a radio station ID?

A station ID is an on-air announcement such as, “You’re listening to Example FM, serving River Town.” Real broadcast stations may use their call sign, frequency, city of license, network name, or slogan in the announcement.

What is a SiriusXM Radio ID used for?

A SiriusXM Radio ID can be used to begin an account search. Have the Radio ID or VIN of your old car handy when registering an account; to transfer service, you will need the Radio ID or VIN of the new car.
