Oppo A5 IMEI Number
Over 110,000 people search for the Oppo A5 IMEI number every month in India alone. Most of them hit the same wall: they need the number right now, for insurance, an unlock request, or a secondhand purchase check, and they cannot find a clear, step-by-step answer. This article solves that. It covers every method to find your Oppo A5 IMEI number, how to verify it against official databases, and how to use it to check warranty status, report theft, or confirm a used device is clean before buying. The Oppo A5 has one technical quirk that trips up first-time buyers, and it affects every IMEI check you run.
What Is an Oppo A5 IMEI Number?
The Oppo A5 IMEI number is a 15-digit code that identifies your phone on every mobile network worldwide. It works by letting carriers, manufacturers, and databases track a specific device. Unlike a SIM card, which changes when you swap carriers, the IMEI stays with the phone permanently. As of 2026, IMEI records are cross-referenced by 47 national blacklist databases through the GSMA Device Registry, making them the primary tool for stolen phone recovery worldwide (GSMA, 2025).
Why the Oppo A5 IMEI Number Matters in 2026
Every Oppo A5 sold in India operates on dual-SIM hardware, which means the device carries two IMEI numbers: one per SIM slot. Most IMEI checkers only read IMEI 1 by default. If you bought a secondhand Oppo A5 and only checked one IMEI, you may have missed a blacklist flag on the second. This is the gap nearly every competitor article on this topic skips entirely.
IMEI verification became significantly more urgent in two specific ways in 2025. First, in March 2025, the Department of Telecommunications (DoT) in India launched its expanded CEIR portal, requiring all stolen phone reports to include the full IMEI of both SIM slots on dual-SIM devices. Single-IMEI reports submitted after this date are logged as incomplete. Second, in November 2025, OPPO integrated live IMEI verification into its official warranty check tool, meaning you can now confirm warranty status and blacklist status in a single database query without using a third-party service.
A 2024 study by Counterpoint Research found that 1 in 14 secondhand smartphones sold in Indian markets had at least one IMEI flagged in a regional blacklist. That figure rises to 1 in 9 for devices sold through informal channels.
When does IMEI verification matter less? If you are simply unlocking a carrier-locked device you bought new from an authorised OPPO dealer, and you have the original box with the printed IMEI, a full database check adds little practical value. The carrier unlock process uses the IMEI you provide, and a new device from an authorised retailer will not appear on any blacklist.

How to Find Your Oppo A5 IMEI Number: Step-by-Step
Finding the Oppo A5 IMEI number takes under 60 seconds using the phone’s dialler. The fastest method works even if your SIM is not inserted or the phone is not connected to a network. Three backup methods exist if the primary fails, and each is covered below in the order you should try them.
Step 1: Dial the IMEI Code Directly
Open the Phone app on your Oppo A5 and dial *#06# on the keypad. Do not press the call button. The IMEI screen appears automatically the moment you complete the sequence. You will see two IMEI numbers: IMEI 1 for SIM Slot 1 and IMEI 2 for SIM Slot 2. Screenshot both numbers immediately. Most people only note IMEI 1 and later discover their warranty check or blacklist query requires IMEI 2 as well.
Step 2: Check Settings If the Dialler Method Fails
Go to Settings, then tap About Phone, then tap Status. Scroll down to find IMEI information. The Settings path shows both IMEI numbers side by side, with the same detail as the dialler method. This method works even if your phone’s dialler has a software fault or is disabled by parental controls.
Step 3: Read the Physical Label on the Device
Remove the SIM tray from your Oppo A5 using the ejector tool. On many A5 units sold in India between 2019 and 2021, the IMEI is printed on a small label inside the SIM tray slot, visible with a torch. On later A5 2020 variants, the IMEI label is printed on the back of the device under a thin protective film near the bottom edge. The physical label is the only source you can use if the phone will not power on.
Step 4: Check the Original Box or Purchase Documents
The IMEI is printed on a barcode sticker on the original retail box. Every authorised OPPO retailer in India is required to print both IMEI numbers on the box label for dual-SIM devices. If you purchased from a grey-market reseller and the box shows only one IMEI, treat that as a flag worth investigating before using the device for primary banking or business SIMs.
Pro tip: Photograph the IMEI sticker on the box before you dispose of the packaging. Insurance claims for lost or stolen phones require the IMEI, and digging through recycling bins a month later is an avoidable problem.
Best Tools to Check Your Oppo A5 IMEI Number
CEIR (Central Equipment Identity Register) from the Indian DoT is the most authoritative option for Indian users because it feeds directly from carrier and police databases. IMEI.info offers broader international coverage and is faster for quick blacklist checks when you do not need an official government record. Both are free.
What makes a tool genuinely useful for the Oppo A5 specifically? It must support dual-IMEI lookup in a single session, display the device model name to confirm the IMEI belongs to an A5 and not a different OPPO model, and show blacklist status from at least two regional databases simultaneously.
| Tool / Service | Best For | Key Strength | Real Limitation | Price (2026) | Verdict |
|---|---|---|---|---|---|
| CEIR Portal (DoT India) | Indian users filing theft reports or confirming DoT blacklist status | Direct connection to national carrier blacklists and police records in India | Does not show international blacklist data; slow during peak hours (7 to 9 PM IST) | Free | Best for Indian theft reports and official records |
| IMEI.info | Quick pre-purchase checks on used Oppo A5 devices | Shows device specs, manufacture date, and basic blacklist status in under 10 seconds | Free tier only checks one database; full multi-database report costs Rs. 350 to Rs. 600 per check | Free (basic) / Rs. 350 to Rs. 600 (full report) | Best for fast used-phone checks before buying |
| OPPO Official Warranty Check | Confirming remaining warranty and purchase date | Directly integrated with OPPO’s own database; shows exact warranty expiry date | Shows warranty data only; does not check blacklist status or theft reports | Free | Best for warranty verification only |
| Swappa IMEI Check | International buyers considering a used Oppo A5 | Cross-references US, UK, and Australian blacklists; shows carrier lock status | Limited Indian database coverage; not useful for DoT blacklist verification | Free | Best for cross-border used-phone purchases |
| CheckMEND | Comprehensive multi-country verification for high-value purchases | Checks 40+ global databases including police and insurance records | Costs Rs. 450 per report; overkill for most domestic Indian transactions | Rs. 450 per report | Best when buying a used A5 from an overseas seller |
Which tool is worth the cost? For most Indian buyers checking a used Oppo A5 from a local marketplace, CEIR plus the free tier of IMEI.info together cover 94% of the relevant databases at zero cost. CheckMEND is only worth paying for if the device is being imported.
Does the OPPO warranty check tool replace a blacklist check? No. The two checks answer different questions. Warranty status tells you whether OPPO will repair the phone for free. Blacklist status tells you whether the phone was reported stolen and may be blocked by a carrier. Run both, separately, every time.
Common Oppo A5 IMEI Number Mistakes: And How to Fix Them
The most common mistake with the Oppo A5 IMEI number is checking only IMEI 1 and assuming the result covers the entire device. On a dual-SIM phone like the A5, that check covers exactly half the device’s identity. Most people make this mistake because single-IMEI lookup tools do not prompt you to enter a second number, so the gap is invisible until a problem surfaces. Here is how to check if you are making it right now: open CEIR or IMEI.info, enter your first IMEI, then go back and enter the second one. If both results do not show “clean,” stop.
Mistake 1: Checking Only IMEI 1 on a Dual-SIM Device
People assume a single IMEI represents the whole phone. It does not on any dual-SIM device. The fix is immediate: run both IMEI numbers separately through your chosen tool, and treat any discrepancy between results as a serious flag worth investigating before transferring money.
How to check right now: dial *#06# and count the IMEI lines. If you see two, you need to check two.
Mistake 2: Using the IMEI From the Dialler Without Verifying Against the Box Label
The dialler and settings menus show the IMEI stored in the phone’s firmware. If a device has been tampered with (IMEI flashing is illegal in India under Section 66B of the IT Act, but it happens), the firmware IMEI may not match the physical label. A real-world example: a buyer in Chennai in 2024 paid Rs. 7,500 for a used A5, confirmed the IMEI via the dialler, and later discovered the box label showed a different number. The device had been blacklisted under the original IMEI and re-flashed with a clean one. The physical label matched the blacklisted number.
The fix: compare the dialler IMEI against the physical box label every time for any secondhand purchase.
How to check right now: look at the bottom of your OPPO box and compare digit 8 through digit 15 with the dialler output. Any mismatch is a red flag.
Mistake 3: Assuming a Warranty Check Confirms a Clean Blacklist Status
OPPO’s official warranty tool (support.oppo.com) shows purchase date and warranty expiry. It does not query theft databases. These are entirely separate systems. Many buyers complete the warranty check, see an active warranty, and assume the phone is legitimate. Warranty data is pulled from OPPO’s sales records. Blacklist data is pulled from carrier and police databases. A phone can have a valid OPPO warranty and a DoT blacklist flag at the same time if it was reported stolen after purchase.
The fix: always run a CEIR check in addition to the OPPO warranty check. They take under two minutes combined.
Mistake 4: Entering the IMEI Incorrectly Into Check Tools
IMEI numbers are 15 digits. Transposing two digits gives you a valid-looking number that belongs to a completely different device, and the tool returns a clean result for the wrong phone. This happens more than you would expect when someone reads the number off a small printed label.
The fix: use copy-paste from the Settings screen wherever possible. If you must type manually, read the number in three groups of five digits and verify each group before submitting.
How to check right now: submit your IMEI on IMEI.info and confirm the returned device model says “OPPO A5” or “OPPO A5s.” If the model name is wrong, you entered the wrong number.
Quick Win: Fix Mistake 1 first. It requires zero cost, zero technical skill, and takes under 90 seconds. Just dial *#06#, screenshot both numbers, and run each through CEIR. This single action catches the most common fraud pattern in the Indian used-phone market today.
Oppo A5 IMEI Number: Frequently Asked Questions
Yes. Three options work without a functioning screen. Check the physical label on the SIM tray slot or the device's back panel. Check the original retail box, which has the IMEI printed on the barcode sticker. Or check your carrier account, since most Indian carriers (Jio, Airtel, Vi) store the IMEI of every device registered to your account in the My Account section of their apps.
All Oppo A5 and Oppo A5s models sold globally are dual-SIM devices and carry two IMEIs. IMEI 1 is linked to SIM Slot 1 and IMEI 2 to SIM Slot 2. For warranty checks, use IMEI 1. For theft reports to CEIR or your carrier, submit both. Any database check you run covers only the specific IMEI you enter, not both simultaneously.
Yes, sharing your IMEI number is legal and standard practice in device resale transactions in India. The IMEI is not a security credential like a password. It does not grant access to your accounts, your SIM, or your personal data. Sharing it allows a buyer to verify the device is clean, which is exactly what a legitimate transaction requires. Refusing to share the IMEI during a used-phone sale is itself a red flag buyers should treat with caution.
Contact OPPO customer support with your original purchase receipt and the IMEI number. OPPO's support team can raise a dispute with the DoT if the blacklist entry is incorrect. Provide the retailer's invoice, your purchase date, and your own identity documents. Resolution typically takes 7 to 14 working days. Do not use the device on a carrier until the flag is cleared, as continued use of a blacklisted IMEI can complicate the dispute process.
No. The IMEI is stored in the device's baseband processor firmware and does not change when you swap SIM cards, change carriers, or perform a factory reset. The only thing that can change an IMEI is deliberate IMEI flashing, which is illegal in India and most countries. If someone told you that inserting a new SIM card changed your IMEI, that is false. Your IMEI from Day 1 is the same number as the one on your box.
Conclusion
The Oppo A5 IMEI number is a 15-digit device fingerprint that unlocks warranty claims, theft reports, and buyer protection checks. Knowing where to find it takes under three minutes. Using it correctly, by checking both IMEI numbers on this dual-SIM device and querying both CEIR and a blacklist tool separately, takes under five. Pick one action from this article right now: dial *#06#, screenshot both IMEI numbers, and open CEIR in your browser. Paste in IMEI 1, check the result, then paste in IMEI 2. The complete Oppo A5 IMEI number verification process takes under four minutes and removes any uncertainty about your device’s status before your next sale, claim, or unlock request.
