Why the Aqara Doorbell Serial Number Matters

When it comes to smart home devices, the Aqara doorbell stands out as one of the most reliable and feature-rich options on the market. Whether you’re troubleshooting an issue, seeking warranty support, or simply trying to register your device with Aqara’s ecosystem, knowing how to find your Aqara doorbell serial number is an essential skill. The serial number is not just a string of digits—it’s your key to unlocking customer support, verifying authenticity, and integrating your doorbell with other smart home platforms like Apple HomeKit, Google Home, or Amazon Alexa.

Many users overlook the importance of this small but critical piece of information until they need it most. Imagine trying to contact Aqara support after a power surge disables your doorbell, only to realize you can’t locate the serial number. Or worse, attempting to return a defective unit to Amazon or another retailer without proof of purchase or product identification. This guide is designed to eliminate those headaches by walking you through multiple proven methods to locate your Aqara doorbell serial number—quickly, easily, and without frustration. Whether you’ve just unboxed your device or have had it installed for months, this article ensures you’ll never be left in the dark again.

Understanding the Aqara Doorbell and Its Serial Number

Before diving into the methods for finding the serial number, it’s important to understand what the Aqara doorbell is and why its serial number is so valuable. Aqara, a Xiaomi-backed smart home brand, offers several models of video doorbells, including the Aqara Video Doorbell G2H Pro, G3, and the Wired Doorbell H1. These devices integrate seamlessly with Apple HomeKit, offer 1080p or higher video quality, two-way audio, motion detection, and local storage options. Each unit comes with a unique serial number that acts as its digital fingerprint.

What Is a Serial Number?

A serial number is a unique identifier assigned to a specific product during manufacturing. For Aqara doorbells, this number helps distinguish one unit from another, even if they are the same model and color. It’s used for:

• Warranty registration and claims
• Customer support and troubleshooting
• Firmware updates and compatibility checks
• Anti-counterfeiting verification
• Integration with third-party platforms (e.g., HomeKit pairing)

Unlike MAC addresses or Wi-Fi SSIDs, the serial number is permanent and never changes, making it the most reliable way to identify your device.

Where Is the Serial Number Used?

You may need the serial number in several scenarios:

• During setup: When pairing the doorbell with the Aqara app or HomeKit, you might be prompted to enter the serial number or scan a QR code that includes it.
• For support: Aqara customer service will ask for the serial number to verify your purchase and troubleshoot issues.
• For returns or exchanges: Retailers often require the serial number to process warranty claims or returns.
• For firmware updates: Some advanced users manually check for firmware updates using the serial number on Aqara’s support portal.

Knowing where to find it ahead of time saves time and stress during critical moments.

Method 1: Finding the Serial Number on the Original Packaging

The easiest and most reliable way to locate your Aqara doorbell serial number is by checking the original packaging. Aqara includes the serial number on the retail box in multiple formats, making it accessible even if the device is already installed.

Locating the Label on the Box

When you open the Aqara doorbell box, look for a white or gray adhesive label typically placed on the bottom, side, or back of the box. This label contains several important details, including:

• Model number (e.g., G2H Pro, G3)
• Serial number (often labeled as “SN:”)
• Barcode or QR code
• Manufacturing date and batch number
• Compliance certifications (CE, FCC, etc.)

For example, the serial number might appear as SN: 20231015G2H0012345. The format varies slightly by model but always starts with “SN:” followed by a 15–18 digit alphanumeric code.

Tips for Preserving the Packaging

If you’re still using the original box, keep it in a safe place—ideally in a closet or storage bin. Here are a few practical tips:

• Store the box upright to prevent label damage.
• Take a clear photo of the label and save it in your phone’s cloud storage (Google Drive, iCloud, etc.).
• Write the serial number in your smart home setup journal or a dedicated app like Notion or Evernote.
• Use a label maker to create a backup sticker with the serial number and model.

Pro Tip: If you’ve already thrown away the box, don’t panic—there are other methods below. But if you’re planning to purchase a new Aqara doorbell, keep the packaging for at least 1–2 years to cover the warranty period.

Method 2: Finding the Serial Number on the Doorbell Device Itself

If the original box is unavailable, the next best place to find the serial number is directly on the doorbell unit. Aqara prints or engraves the serial number on the physical device, usually in a discreet but accessible location.

Where to Look on the Doorbell

The exact location varies by model, but here are common spots:

• Back panel: Remove the doorbell from the mounting bracket (if installed) and check the back. The serial number is often printed on a small white label or etched into the plastic.
• Inside the battery compartment: For battery-powered models like the G2H Pro, open the rear battery cover. The serial number is typically printed on the inner wall or on a sticker near the battery slots.
• Bottom edge or side: Some models have a small engraved plate or sticker on the bottom or side edge of the device.
• Under the mounting plate: If the doorbell is wired and mounted, the serial number might be visible only after removing the front housing (requires a screwdriver).

For example, the Aqara G2H Pro has the serial number printed on a sticker inside the battery compartment. You’ll need to slide the battery cover open and look toward the top edge of the cavity. The sticker includes both the serial number and a QR code.

Step-by-Step: How to Access the Serial Number

1. Power off the doorbell (if wired, turn off the circuit breaker for safety).
2. Remove the doorbell from the mounting bracket using the release key or screwdriver.
3. Open the battery compartment or inspect the back panel.
4. Use a flashlight or phone light to illuminate dark areas.
5. Take a clear photo of the serial number label for future reference.

Caution: Avoid using sharp tools to pry open the device. If the label is faded or damaged, try using a magnifying glass or high-resolution camera to read it.

What If the Label Is Damaged?

If the label is scratched, water-damaged, or missing, try the following:

• Contact Aqara support with a photo of the device and purchase receipt—they may be able to identify the unit based on other data.
• Check the Aqara app (see Method 3) for the serial number.
• If you have the QR code, scan it with a QR reader—the serial number is often embedded in the data.

Method 3: Finding the Serial Number in the Aqara App

For users who have already set up their Aqara doorbell, the Aqara Home app provides a digital way to access the serial number—no need to physically inspect the device or box.

Accessing Device Info in the Aqara App

Follow these steps to find the serial number:

1. Open the Aqara Home app on your smartphone or tablet.
2. Tap on the “Devices” tab at the bottom.
3. Locate your doorbell in the list and tap on it to open its control panel.
4. Tap the gear icon (⚙️) in the top-right corner to access device settings.
5. Scroll down and tap on “Device Information” or “About This Device”.
6. Look for the “Serial Number” field—it will display the full SN code.

The app may also show additional details like firmware version, Wi-Fi MAC address, and model number.

Using the App for Troubleshooting

The Aqara app is particularly useful if you’re experiencing connectivity issues. For example:

• If the doorbell won’t connect to Wi-Fi, you can copy the serial number and paste it into Aqara’s support chat or email.
• If you’re setting up HomeKit, the app may prompt you to enter the serial number manually—having it ready speeds up the process.
• You can also use the app to export device logs, which include the serial number and are helpful for diagnosing hardware problems.

Bonus Tip: Enable cloud backup in the app settings. If your phone is lost or damaged, you can restore your device list (including serial numbers) on a new device.

What If the App Doesn’t Show the Serial Number?

In rare cases, the app may not display the serial number due to a bug or outdated version. Try these fixes:

• Update the Aqara app to the latest version from the App Store or Google Play.
• Restart the app and your phone.
• Re-pair the doorbell (remove and re-add it in the app).
• Log out and log back into your Aqara account.

Method 4: Using Third-Party Platforms and Integration Hubs

If you’ve integrated your Aqara doorbell with platforms like Apple HomeKit, Google Home, or Home Assistant, you may be able to retrieve the serial number through those systems—even if the Aqara app or physical device is inaccessible.

Finding the Serial Number in Apple HomeKit

For HomeKit users, follow these steps:

1. Open the Apple Home app.
2. Tap on the doorbell accessory.
3. Tap the info icon (ⓘ) in the top-right corner.
4. Scroll down to “Serial Number”—it should match the one on the device or box.

HomeKit displays the serial number as part of the accessory metadata, making it easy to access during troubleshooting.

Using Home Assistant or SmartThings

In Home Assistant, the serial number may appear in the device registry:

1. Go to Settings > Devices & Services.
2. Find your Aqara doorbell in the list.
3. Click on it and look for “Serial Number” in the attributes section.

For SmartThings, the process is similar—navigate to the device details page and check the “About” section.

Why Use Third-Party Platforms?

These methods are especially helpful if:

• You’ve lost access to the Aqara app (e.g., account deleted).
• The doorbell is installed in a hard-to-reach location (e.g., second floor).
• You’re managing multiple Aqara devices and need a centralized view.

Note: Not all third-party platforms display the serial number. Apple HomeKit is the most reliable for this purpose.

Method 5: Contacting Aqara Support for Assistance
