The quickest way to find your SiriusXM Radio ID (also called an ESN or SID) is to turn on your radio and tune to Channel 0. If that doesn't work, the ID is almost always accessible through your vehicle's infotainment screen. You can usually find it in the SiriusXM menu under "Settings," "Satellite Radio," or "Radio Info." For some older models, you may need to check the physical radio unit itself.
The Radio ID is a 12-character alphanumeric code (letters and numbers). It's essential for activating or managing your SiriusXM subscription. The exact steps vary significantly by car manufacturer and model year. Here’s a breakdown of the most common methods:
1. On the Radio Display (Most Common Method)
2. Through the Vehicle Information Menu In some vehicles (like certain Hondas or Acuras), you may find the Radio ID outside the SiriusXM app. Look in your main system settings menu for "Vehicle Information," "System Information," or "Diagnostics."
3. Physical Inspection (Older or Aftermarket Radios) If you have an older car or an aftermarket SiriusXM receiver, the ID might be printed on a label on the radio unit itself. You may need to remove the radio from the dashboard to see it. For some very old models, the ID can be found on a sticker in the trunk, glove box, or on the underside of the radio.
If you're still stuck, the most reliable source is the SiriusXM Online Account Portal. If your radio was previously active, you can log in to your account and the ID will be listed under your “My Equipment” section.

Easiest way? Just turn on your car and flip to Channel 0 on your Sirius radio. Wait a sec, and the ID should pop right up on your screen. If that doesn't work, dig around in your stereo's Sirius menu. Look for "Settings" or "Radio Info." It's a long mix of letters and numbers you'll need to copy down for customer service or to activate a subscription online.

I'm a visual guy, so here's what I did in my F-150. I pressed the "SiriusXM" button on the dash. Then, I tapped the "Menu" or "Settings" icon on the touchscreen. I scrolled down until I saw "Satellite Radio," tapped it, and then there it was: "Radio ID." I just snapped a picture of the screen with my phone. No writing anything down. Your car's menu might be a little different, but that's the general idea—it's buried in the satellite radio settings.

Honestly, I just called SiriusXM. I was in my driveway, my on speaker. I told the rep I needed to activate my trial. They asked for my car's VIN, which I read off the sticker on the driver's side doorjamb. About thirty seconds later, they had my Radio ID and had me tuned in. Zero digging through menus. It was a lot easier than me fumbling with the screen, especially since I wasn't even sure where to look. Sometimes the human way is the best way.

Don't forget about your car's manual—the one you probably tossed in the glove box. It actually has the answer. I looked up "SiriusXM" in the index of my Honda's manual, and it pointed me to the exact sub-menu. Also, if you have a connected car app from the manufacturer on your , like GM's MyBrand app or the FordPass App, your Radio ID might be listed in the vehicle details section there. It’s a neat trick if you’re not actually in the car but want to get your subscription set up ahead of time.
