If you own an Oppo A5, your IMEI number is one of the most useful device identifiers you should know.
You may need it when checking warranty information, reporting a lost or stolen phone, verifying a second-hand device, or contacting your mobile carrier.
The good news is that finding the Oppo A5 IMEI number is simple. In most cases, you can display it in just a few seconds using the phone's dialler.
This guide explains the different ways to find your IMEI and what you should know before using it for device verification.
What Is an IMEI Number?
IMEI stands for International Mobile Equipment Identity.
An IMEI is a unique 15-digit identifier associated with a mobile device.
It is different from your SIM card number.
Your SIM can be removed, replaced, or transferred to another phone, while the IMEI identifies the device itself.
An IMEI can be useful for:
Device identification
Warranty verification
Theft reporting
Used-phone verification
Carrier support
Device status checks
The Oppo A5 is available with dual-SIM functionality, so you may see IMEI 1 and IMEI 2.
Method 1: Use the *#06# Code
The fastest way to find your Oppo A5 IMEI is through the Phone app.
Steps
Open the Phone application.
Open the dial pad.
Type:
*#06#
Don't press the call button.
The IMEI information should appear automatically.
If your device displays two IMEI numbers, save both.
Why Is This Method Useful?
The dialler method is convenient because it doesn't require you to navigate through multiple Settings menus.
It's especially useful when you need the IMEI quickly.
Method 2: Find the IMEI in Settings
You can also retrieve the IMEI through your phone's system settings.
Depending on your ColorOS version, look for:
Settings
↓
About Phone
↓
Status
↓
IMEI Information
The exact menu names can vary depending on the software version installed on your device.
This method is useful when you want to confirm the IMEI directly through the operating system.
Method 3: Check the Physical Device
What happens if your Oppo A5 doesn't turn on?
You may still be able to find the IMEI through the physical labeling on the device.
Depending on the particular A5 variant, check areas such as:
SIM-tray area
Device label
Printed identification information
Because these numbers can be very small, use a flashlight or take a clear photograph and zoom in.
If the phone has no power, physical identification information can be particularly useful.
Method 4: Check the Original Retail Box
If you still have the original Oppo A5 packaging, check the barcode sticker.
The box may contain:
IMEI number
Device information
Barcode
Serial information
Product details
Compare the IMEI printed on the box with the IMEI displayed on the phone.
Why Does This Matter?
If you're buying a second-hand phone and the numbers don't match, don't ignore the difference.
An IMEI mismatch can be a reason to investigate the device further before completing the purchase.
Why You Should Check Both IMEIs
A dual-SIM device can have two IMEI numbers.
For example:
SIM Slot 1 → IMEI 1
SIM Slot 2 → IMEI 2
Checking only IMEI 1 doesn't necessarily verify IMEI 2.
When buying a used Oppo A5, consider checking:
IMEI 1
IMEI 2
Original box
Warranty information
Device status
This gives you a more complete picture of the phone.
How to Check an Oppo A5 IMEI
After finding the IMEI, you may want to verify the device.
For users in India, the CEIR (Central Equipment Identity Register) is an important official resource for device blocking and stolen-phone related checks. Other third-party IMEI services may provide additional information, but their coverage varies.
You can also use the manufacturer's official warranty-check resources when your goal is to confirm warranty information.
Important Difference
Don't confuse:
Warranty status
with
Blacklist status
They answer different questions.
A phone can have warranty information available while still requiring a separate blacklist or stolen-device check.
Common IMEI Checking Mistakes
Mistake 1: Checking Only One IMEI
If your phone has two IMEIs, don't assume that checking one automatically checks the other.
Solution
Find both numbers using:
*#06#
Then check each one separately where required.
Mistake 2: Not Comparing the Box and Phone
If you're buying a used phone, compare the numbers from the device and original box.
If they differ, ask the seller for an explanation and verify the device before proceeding.
Mistake 3: Confusing IMEI With a Model Number
An IMEI is generally a 15-digit numeric identifier.
The phone's model information is a different identifier.
Don't enter the wrong number into an IMEI verification service.
Mistake 4: Entering the Wrong Digits
IMEIs are long, so manually typing them can result in errors.
If possible:
Copy the number from Settings.
Take a screenshot.
Compare every digit.
Verify the returned device information.
A single incorrect digit can produce an incorrect lookup result.
Best Practices for Your Oppo A5 IMEI
Once you find your IMEI, keep a secure record.
You can:
Photograph the original box.
Save the information in a secure note.
Keep your purchase invoice.
Store warranty documentation safely.
Don't unnecessarily post your IMEI publicly on social media or online forums.
