Where Is the Serial Number on a Aqara Doorbell Find It Fast

The Aqara Doorbell’s serial number is typically located on the back of the device or inside the battery compartment—check the small printed label for a 12- to 16-digit alphanumeric code. If you’ve already installed it, you can also find the serial number in the Aqara app under device settings. Having trouble? A quick scan of the original packaging or receipt may also reveal the number for fast access.

• Inspect the packaging: Find the serial number on the box’s barcode label.
• Open the Aqara app: Device details in the app list the serial number.
• Look under the battery cover: Some models hide the serial number here.
• Scan the QR code: Often contains or links to the serial number.

Why You Need to Know Where the Aqara Doorbell Serial Number Is

Smart home devices like the Aqara Doorbell have revolutionized how we interact with our living spaces. From real-time video monitoring to AI-powered motion detection and seamless integration with ecosystems like Apple HomeKit, Google Home, and Amazon Alexa, these devices offer convenience, security, and peace of mind. But as with any electronic device, there comes a time when you need to locate critical information—specifically, the serial number. Whether you’re troubleshooting connectivity issues, registering your product for warranty, seeking technical support, or preparing to sell your doorbell, the serial number is your key to unlocking essential services and support.

Finding the serial number on an Aqara Doorbell might seem like a trivial task, but many users—especially first-time smart home adopters—often struggle with this. Unlike traditional doorbells, smart doorbells are compact, designed with minimalist aesthetics, and often lack visible labels due to waterproofing and tamper-resistant casings. This makes locating the serial number more of a detective mission than a quick glance. In this guide, we’ll walk you through exactly where to find the serial number on various Aqara Doorbell models, why it matters, and how to access it quickly—whether your device is still in the box or already installed on your front porch. By the end, you’ll know how to find it fast, avoid common mistakes, and keep your smart home running smoothly.

Understanding the Aqara Doorbell Models and Their Serial Number Locations

Aqara offers several doorbell models, each with slightly different designs, features, and—critically—serial number placements. Knowing which model you own is the first step to locating the serial number efficiently. The most common models include the Aqara Video Doorbell G2H Pro, Aqara Video Doorbell G2H, Aqara Smart Doorbell H1, and the Aqara Doorbell Camera (Wired & Wireless). While all serve the same primary purpose—providing video and audio access to your front door—their physical layouts and labeling strategies vary.

1. Aqara Video Doorbell G2H Pro

The G2H Pro is one of Aqara’s flagship models, featuring 1080p HD video, night vision, local storage, and HomeKit Secure Video compatibility. Its sleek, rectangular design includes a front-facing camera, motion sensor, and a prominent button. The serial number on this model is typically located on a sticker on the back side of the main doorbell unit, just above the mounting screw holes. To access it:

• Remove the doorbell from its mounting bracket (you’ll need a small Phillips screwdriver).
• Turn the device over—look for a white or silver sticker with a QR code and a 12- to 16-character alphanumeric code labeled “S/N” or “Serial No.”
• Alternatively, the serial number may be printed on the inside of the protective silicone cover (if included).

Tip: If the sticker is worn or damaged, check the original packaging—Aqara often includes a duplicate sticker on the box.

2. Aqara Video Doorbell G2H (Standard)

The standard G2H model shares many features with the Pro but has a slightly different form factor and internal layout. The serial number is usually found in two places:

• On the back of the main unit: A small recessed label near the charging port or reset button.
• Inside the battery compartment: If your G2H uses a removable battery, the serial number may be printed on a label beneath the battery. Simply slide out the battery tray to access it.

Some early production batches placed the serial number only on the packaging, so if you can’t find it on the device, double-check the box or manual.

3. Aqara Smart Doorbell H1

The H1 is a budget-friendly, wired-only model with no battery compartment. Its serial number is almost always located on the back panel of the doorbell, covered by a thin protective film. To view it:

• Carefully peel back the film (it’s reusable).
• Look for a sticker with the S/N, model number (e.g., DB-H1), and regulatory markings.

Unlike the G2H series, the H1 does not have a QR code on the device itself—instead, the QR code is printed on the box and in the Aqara app during setup.

4. Aqara Doorbell Camera (Wired & Wireless)

This model, often referred to as the “Aqara Doorbell Camera,” comes in both wired and battery-powered versions. The serial number location depends on the variant:

• Wired version: Serial number is on the back of the unit, behind a removable cover. Use a flat tool to gently pry open the cover.
• Wireless version: The number is printed inside the battery compartment. Remove the battery to reveal the label.

Both versions include a duplicate serial number on the original packaging, so keep the box if possible.

How to Locate the Serial Number When the Doorbell Is Already Installed

One of the most common scenarios users face is needing the serial number after the Aqara Doorbell is already mounted. Whether you’re troubleshooting a Wi-Fi drop, updating firmware, or contacting Aqara support, you don’t want to dismantle your doorbell unnecessarily. Fortunately, there are several ways to access the serial number without removing the device.

Using the Aqara Home App (Recommended Method)

The Aqara Home app (available on iOS and Android) stores device information, including the serial number, once the doorbell is paired. Here’s how to find it:

1. Open the Aqara Home app and log in to your account.
2. Navigate to “Devices” and select your Aqara Doorbell from the list.
3. Tap the gear icon (⚙️) to enter the device settings.
4. Scroll down to “Device Information” or “About Device.”
5. Look for a field labeled “Serial Number” or “Device ID.” This is your official S/N.

Pro Tip: Take a screenshot of this screen and save it in your cloud storage (e.g., Google Drive, iCloud) for future reference. This way, you’ll always have it—even if the app gets deleted or the phone is lost.

Checking the Original Packaging and Documentation

If you still have the original box, you’re in luck. Aqara prints the serial number in at least three places:

• On a sticker on the side or bottom of the box.
• In the quick start guide or warranty card (often near the barcode).
• On the plastic tray inside the box (sometimes laser-etched).

Even if the device is installed, the box can serve as a permanent backup. Consider storing it in a labeled bin or drawer for smart home accessories.

Using a Mirror or Phone Camera to Read the Back Label

For doorbells mounted at eye level or higher, use a small mirror or your smartphone’s camera to view the back of the unit:

• Angle a mirror to reflect the back panel of the doorbell.
• Or, use your phone’s rear camera to take a photo from behind the device (you may need a helper).
• Zoom in on the image to read the serial number.

This method works best with the G2H Pro and H1 models, where the label is flush with the surface.

When Physical Access Is Unavoidable

If the label is damaged, faded, or obstructed (e.g., by paint, dirt, or a protective cover), you may need to remove the doorbell temporarily. Always follow these steps:

• Power off the device (for wired models, turn off the breaker).
• Use the correct tool (usually a small screwdriver) to unscrew the mounting plate.
• Detach the unit and photograph the serial number label.
• Reinstall promptly to maintain weatherproofing.

Note: Avoid using abrasive cleaners on the label, as they can erase printed text.

Why the Serial Number Matters: Key Use Cases

You might wonder, “Why do I even need the serial number?” The answer: it’s more important than you think. The serial number is a unique identifier that unlocks a range of critical functions and services. Here are the top reasons why you should always know where to find it.

1. Warranty Registration and Claims

Aqara offers a standard 12- to 24-month warranty on most doorbell models. To register your warranty, you must provide the serial number. Without it, Aqara support may deny your claim. For example, if your G2H Pro stops recording after six months, you’ll need the S/N to initiate a repair or replacement process. Some retailers (like Amazon or Best Buy) also require the serial number for extended warranty claims.

2. Technical Support and Troubleshooting

When contacting Aqara customer support, agents will almost always ask for the serial number. It allows them to:

• Verify the model and firmware version.
• Check for known bugs or recalls.
• Access your device’s diagnostic logs.

For instance, if your doorbell isn’t connecting to HomeKit, support can cross-reference your S/N with Apple’s HomeKit database to ensure compatibility.

3. Firmware Updates and Security Patches

Aqara rolls out firmware updates to improve performance, add features, and patch security vulnerabilities. These updates are often tied to the serial number range. If your doorbell isn’t receiving updates, the serial number helps Aqara determine if it’s part of a specific batch that requires a manual patch.

4. Device Resale and Ownership Transfer

Planning to sell your Aqara Doorbell? Buyers will want proof of authenticity and warranty status. The serial number allows them to verify the device’s legitimacy and check for blacklisting (e.g., if it was reported stolen). It also enables a smooth transfer of ownership in the Aqara app.

5. Integration with Smart Home Ecosystems

For HomeKit, Google Home, or Alexa integration, the serial number (or its embedded MAC address) is used to authenticate the device. If you’re setting up the doorbell on a new network, having the S/N on hand speeds up the pairing process.

Common Mistakes When Looking for the Serial Number (And How to Avoid Them)

Even with clear instructions, users often make avoidable errors when searching for the serial number. Here are the most common pitfalls and how to steer clear of them.

Mistake 1: Confusing the Model Number with the Serial Number

The model number (e.g., DB-G2H, H1) and serial number (e.g., SN1234567890AB) are different. The model number tells you the type of device, while the serial number is unique to your unit. Always look for the label that says “S/N” or “Serial No.” Avoid using the model number in support requests—it won’t work.

Mistake 2: Overlooking the Packaging

Many users discard the box immediately after setup. But the packaging is a goldmine of information. Keep the box for at least 6 months after purchase, or take clear photos of the serial number sticker and store them digitally.

Mistake 3: Assuming All Models Have the Same Label Placement

As we’ve seen, the G2H Pro has the label on the back, while the G2H hides it under the battery. Never assume—check the specific model’s manual or app first. Aqara’s official website provides detailed diagrams for each model.

Mistake 4: Damaging the Label During Cleaning

Wiping your doorbell with a wet cloth or cleaning spray can smudge or dissolve the printed serial number. Use a dry microfiber cloth only. If the label is already damaged, contact Aqara support with proof of purchase (receipt + photo of damaged label) to request a replacement sticker.

Mistake 5: Not Recording the Serial Number After Setup

Don’t wait until you need the serial number to look for it. As soon as your Aqara Doorbell is installed, record the S/N in a secure place. Use a password manager (like 1Password or Bitwarden) to store it alongside your Wi-Fi password and router details.
