Before we dive into the “how,” let’s talk about the “why.” Why is the serial number so important?
First, during the initial setup of your Blink doorbell, the app will ask you to scan or enter the serial number. This helps the system identify your specific device and link it to your account. Without it, you can’t complete the setup process.
Second, if your doorbell stops working or you’re experiencing connectivity issues, Blink’s customer support team will almost always ask for the serial number. It helps them verify your device, check warranty status, and provide accurate troubleshooting steps.
Third, if you ever need to return or replace your doorbell, the serial number proves ownership and ensures you’re getting the right replacement.
In short, the serial number is like your doorbell’s ID card. Keep it handy—you’ll likely need it more than once.
Method 1: Find the Serial Number on the Device Itself
The most direct way to find your Blink doorbell serial number is to look at the physical device. Here’s how to do it safely and effectively.
Step 1: Remove the Doorbell from the Mount (If Installed)
If your Blink doorbell is already mounted on your doorframe or wall, you’ll need to take it down to access the serial number. Don’t worry—this is easier than it sounds.
Start by turning off the power to your existing doorbell at the circuit breaker. This is a safety precaution, especially if you’re working near electrical wiring.
Next, gently slide the Blink doorbell upward to release it from the mounting bracket. Most Blink models use a simple slide-and-lock mechanism. If it feels stuck, wiggle it slightly while pulling up.
Once removed, place the doorbell on a flat, stable surface where you can examine it closely.
Step 2: Locate the Serial Number Label
Now, turn the doorbell over and look at the back or bottom edge. You’re looking for a small white or silver label with a string of numbers and letters.
On most Blink Video Doorbells and Outdoor cameras, the serial number is printed on a sticker near the bottom of the device. It usually starts with “BLS” or “BLX” followed by a series of digits (e.g., BLS123456789).
For the Blink Mini, the label is typically on the bottom of the camera unit. Flip it over and look for a small rectangular sticker.
If you have a Blink Doorbell with a Sync Module (like older XT or Outdoor models), the doorbell itself may not have a visible serial number. In that case, check the Sync Module—it’s a small black box that connects to your router and usually has the label on the bottom or side.
Step 3: Read and Record the Serial Number
Once you’ve found the label, carefully read the serial number. It’s easy to mix up numbers and letters (like “0” and “O” or “1” and “I”), so take your time.
Write it down or, better yet, take a clear photo with your phone. Store the photo in a secure folder or cloud service so you can access it later.
Pro Tip: Use a magnifying glass or your phone’s zoom feature if the text is small or hard to read. Good lighting also helps—natural daylight or a bright lamp works best.
Method 2: Find the Serial Number in the Blink App
If your Blink doorbell is already set up and connected to the app, you can find the serial number without touching the device at all. This is especially useful if your doorbell is hard to reach or you’ve misplaced the original packaging.
Step 1: Open the Blink App
Launch the Blink app on your smartphone or tablet. Make sure you’re logged into the account associated with your doorbell.
If you have multiple devices, ensure you’re viewing the correct system. Tap on the system name at the top of the screen to switch between locations if needed.
Step 2: Navigate to Device Settings
From the home screen, tap on the doorbell you want to check. This will open the live view or recent clips.
Now, look for the gear icon (⚙️) in the top-right corner. Tap it to access the device settings menu.
Step 3: Locate the Serial Number
Scroll down through the settings until you see a section labeled “Device Info” or “About.” Tap on it.
Here, you’ll find details like firmware version, battery level, and—most importantly—the serial number. It will be listed clearly, usually under “Serial Number” or “Device ID.”
Tap and hold the serial number to copy it, or take a screenshot for your records.
Note: This method only works if the doorbell is already connected and functioning. If the device is offline or not yet set up, you’ll need to use one of the other methods.
Method 3: Check the Original Packaging
If you still have the box your Blink doorbell came in, the serial number is likely printed right on it. This is a great backup option, especially if the label on the device is damaged or worn off.
Step 1: Locate the Blink Doorbell Box
Find the original retail box. It’s usually a white or black box with the Blink logo and product image.
Step 2: Look for the Barcode Label
On the side or bottom of the box, you’ll find a large barcode sticker. This label includes the product name, model number, and serial number.
The serial number is typically listed below or next to the barcode. It may be labeled as “S/N,” “Serial No.,” or just appear as a long string of characters.
For example:
**Model:** Blink Video Doorbell
**S/N:** BLS987654321
**UPC:** 123456789012
Step 3: Verify and Save the Number
Double-check that the serial number matches the one on the device (if accessible). If it does, you’ve got a match!
Take a photo of the label or write down the number. Store it in a safe place—maybe even tape a copy inside the box for future reference.
Pro Tip: If you’re buying a used Blink doorbell, always ask for the serial number and verify it matches the packaging. This helps avoid counterfeit or stolen devices.
Method 4: Use the Sync Module (For Older Models)
Some Blink doorbells, particularly the older XT and Outdoor models, require a Sync Module to connect to your Wi-Fi network. If your doorbell uses one, the Sync Module may be the key to finding the serial number.
Step 1: Locate the Sync Module
The Sync Module is a small black box that plugs into a power outlet near your router. It has a green LED light and connects to your network via Ethernet or Wi-Fi.
Step 2: Check the Bottom or Side for a Label
Flip the Sync Module over or look at its side. You should see a label with the serial number, model number, and other details.
The serial number usually starts with “BLX” or “BLS” and is 12 characters long.
Step 3: Use the App to Confirm
Open the Blink app and go to the Sync Module settings (usually under “System Settings”). The app should display the Sync Module’s serial number, which you can compare to the one on the device.
Note: While the Sync Module has its own serial number, the doorbell unit may still have one too. For setup and support, you may need both numbers—so record both if possible.
Method 5: Contact Blink Customer Support
If you’ve tried all the above methods and still can’t find the serial number, don’t panic. Blink’s customer support team can help—but you’ll need to prove ownership.
Step 1: Gather Proof of Purchase
Have your receipt, order confirmation email, or credit card statement ready. Blink will ask for this to verify that you’re the legitimate owner.
Step 2: Reach Out to Support
Visit the official Blink support website or use the in-app help feature. You can chat online, submit a ticket, or call support (if available in your region).
Explain that you need help retrieving your doorbell’s serial number. Provide your account email, device model, and proof of purchase.
Step 3: Follow Instructions
The support agent may ask you to perform a reset or check specific settings. They might also guide you through a process to retrieve the number remotely.
In some cases, they can look up your device using your account information—especially if it was previously registered.
Pro Tip: Be patient and polite. Support teams are more likely to go the extra mile for courteous customers.
Troubleshooting Common Issues
Even with this guide, you might run into a few hiccups. Here’s how to handle the most common problems.
Problem: The Serial Number Label is Worn Off or Missing
Over time, labels can fade, peel, or get scratched—especially if the doorbell is exposed to weather.
Solution: Try using a soft cloth and rubbing alcohol to gently clean the area. Sometimes dirt or grime makes the text hard to read. If the label is completely gone, use the app method or contact support.
Problem: The App Doesn’t Show the Serial Number
If the app skips the “Device Info” section or shows an error, your device might not be fully synced.
Solution: Make sure your doorbell is online and has a strong Wi-Fi signal. Restart the app and try again. If it still doesn’t work, remove and re-add the device to refresh the connection.
Problem: You Can’t Access the Device (It’s Too High or Hard to Reach)
Some doorbells are installed high up or in tight spaces.
Solution: Use a step ladder (safely!) or ask someone for help. Alternatively, use the app or packaging method. If all else fails, contact support with proof of purchase.
Problem: You Bought the Doorbell Secondhand
If the previous owner didn’t reset the device, you might not have full access.
Solution: Perform a factory reset using the reset button (usually on the back or side). Then set it up as a new device. You’ll still need the serial number for setup, so check the label or box.
Tips for Keeping Your Serial Number Safe
Once you’ve found your Blink doorbell serial number, don’t let it slip away again. Here are some smart ways to keep it secure and accessible.
- Take a photo: Snap a clear picture of the serial number label and save it to your phone’s gallery or a cloud storage service like Google Drive or iCloud.
- Write it down: Keep a notebook or digital note with all your smart home device serial numbers. Label it clearly so you can find it fast.
- Store it with manuals: Tape a copy of the serial number inside the user manual or store it in the original box.
- Use a password manager: Many password managers allow you to store secure notes. Add your serial number there with a label like “Blink Doorbell S/N.”
- Email it to yourself: Send a quick email with the serial number and save it in a dedicated folder.
Remember: The serial number is sensitive information. Don’t share it publicly or post it online. Only provide it to Blink support or authorized technicians.
