In Pakistan’s used-phone market, two identical-looking phones can be completely different purchases. One is officially PTA approved on its own IMEI. The other is running on a borrowed IMEI — and can be blocked without warning. On 15 October 2026, PTA restated its standing advice to buyers: verify a phone’s IMEI and legal status before paying, buy from reliable sources, and compare the IMEI on the screen with the IMEI printed on the box. This guide turns that advice into a complete shop routine — including the CPID trap that the basic 8484 check does not catch.
First, Know the Three Kinds of “Approved”
| Type | What it really is | Should you buy it? |
|---|---|---|
| Officially PTA approved | The phone’s own original IMEI is registered in DIRBS with FBR duties/taxes paid | Yes — permanent and legal; the only status worth full price |
| Non-PTA | Original IMEI, never registered | Only at a discount: SIM works briefly, then stops unless DIRBS tax is paid; Wi-Fi keeps working |
| Patched / CPID (“VIP approved”, “server approved”) | The IMEI has been rewritten to a cheap registered phone’s IMEI | No — illegal and risky, however cheap (details below) |
Check 1: Get the IMEI With *#06#
Dial *#06# — the phone’s IMEIs appear instantly. A dual-SIM phone has two IMEIs, and BOTH must be checked; a clean first IMEI tells you nothing about the second slot. You can cross-check in Settings → About phone → Status → IMEI information, and every IMEI is also printed on the box.
Check 2: SMS the IMEI to 8484
- Type the bare 15-digit IMEI — no spaces, dashes or extra words, which can make the lookup fail.
- Send it to 8484. PTA replies within about a minute, and the check costs nothing beyond a normal SMS.
- Read the status carefully:
| 8484 reply | What it means for you |
|---|---|
| Compliant | PTA approved, tax settled → the safe result (but still do the CPID tests below) |
| Non-compliant | Not registered. It may work inside a grace period, then get blocked unless the tax is paid |
| Blocked | Already cut off from all networks — do not buy for SIM use |
| Invalid IMEI | The number is not recognised — a red flag for a cloned or tampered IMEI. Walk away |
Check 3: DIRBS Website and App
For a fuller picture, use PTA’s DIRBS portal (dirbs.pta.gov.pk): enter the IMEI, complete the captcha, and check the status. The website shows more detail than the SMS — including awkward cases like a phone registered for one SIM only. The official DIRBS Pakistan app (Play Store / App Store) does the same check and is handy if you are comparing several phones. The website can be flaky from outside Pakistan, which is why the 8484 SMS remains the reliable in-shop test.
A note on the grace period above: guides summarising DIRBS behaviour report that a new personal import gets about 60 days from its first use on a local network to pay the duty, which is generated against that IMEI inside DIRBS (paid via a PSID). Do not confuse this with the separate 120-day temporary registration for overseas Pakistanis and visitors — they are different facilities.
The CPID Trap: Why “Compliant” on 8484 Is Not Enough
CPID is a server-based technique, used mostly on Samsung Galaxy phones, that permanently rewrites the phone’s IMEI to the IMEI of a cheap, already-registered phone — no root needed, and the change survives factory resets and software updates, which is why sellers market it as “permanent approval”. Its price sits in the middle — more than a patch, less than the official tax — which is exactly why shops push it as the “smart” middle option. The cheaper alternative, a patch, forces a donor IMEI in at software level; it can break with updates or resets, and on Samsung it typically damages Knox security, breaking Samsung Pay and secure features and hurting resale value.
Here is the trap: a CPID or patched phone usually shows “Compliant” on 8484 — because the donor IMEI genuinely is registered. The check alone cannot clear the phone. The risks of owning one:
- IMEI alteration is an offence under the Prevention of Electronic Crimes Act (PECA) 2016, enforced by the FIA, and PTA has run crackdowns on patched devices and patching services.
- PTA can detect the mismatch — an IMEI’s prefix identifies a cheap model, not the flagship in your hand — and patched phones can be blocked later without warning.
- If the donor phone is reported stolen or blocked, your phone dies with it; two phones sharing one IMEI can both be flagged.
- Software updates, banking-app integrity checks and warranty claims can fail.
The Shop Tests That Actually Catch a Patched Phone
- Model–box–screen match. Check both IMEIs on 8484 and on the DIRBS website. The IMEI on the box and in Settings → About phone must match *#06# exactly. Any mismatch means tampering.
- Identity smell-test. If the IMEI’s identity belongs to a cheap phone while you are holding a flagship, it is a donor IMEI. Prefer the DIRBS website check for expensive phones, since it shows more than the SMS.
- Dual-SIM signal test. Insert your own SIM in both slots — make a call, send an SMS and load a page on mobile data in each. A phone registered “for one SIM only”, or partially blocked, fails on the second slot.
- Samsung-specific checks. Ask about Knox status — tripped Knox suggests a patched history. And treat the phrase “CPID / server approved” itself as an admission, especially on a flagship Galaxy priced far below the official-PTA market rate.
- Ignore the reset test. A seller offering to “factory reset it in front of you” proves nothing — CPID survives resets. Rely on the IMEI/box/model matching instead.
On top of these, do the normal used-phone checks: battery health, display burn-in, cameras, charging port, and make sure the phone is not activation-locked to someone else’s iCloud or Google account.
A Five-Minute Shop Routine, In Order
Put together, the checks take about five minutes at the counter. Minute one: dial *#06#, note both IMEIs, and compare them with the box and with Settings → About phone. Minute two: SMS both IMEIs to 8484 and read both replies. Minute three: open the DIRBS website and run the same two IMEIs there, watching for the “one SIM only” detail the SMS can hide. Minute four: put your own SIM in slot one — make a call and load a page on mobile data — then move it to slot two and repeat. Minute five: ask the seller the questions below, and decide.
Any step that fails — a mismatched IMEI, a “one SIM only” surprise, a dead second slot, a refusal to let you check — is not a small defect to negotiate a discount over. It is the answer. Walk away and buy the next phone.
Questions to Ask the Seller
Say these out loud, in front of the phone, before any money changes hands — a genuine seller will not rush you past a single one of them.
- “Is it officially PTA approved on its OWN IMEI, or CPID/patched?” If they claim official, get it in writing on the receipt.
- “Can I check both IMEIs on 8484 and the box myself before paying?” A refusal is your answer.
- “Is there a shop warranty — and does it cover PTA blocking?”
- “Why is it cheaper than other PTA-approved units of the same model?” A big price gap usually means patch/CPID or non-PTA.
- For a non-PTA phone: never accept a verbal tax figure. The exact payable amount is generated per-IMEI inside DIRBS during registration — check it there, not from the seller’s mouth.

FAQs
Q: 8484 says “Compliant”. Is the phone definitely safe to buy?
Not by itself. A CPID/patched phone passes 8484 because the donor IMEI it carries is genuinely registered. Complete the full routine: match both IMEIs against the box and Settings, run the DIRBS website check, and do the dual-SIM signal test with your own SIM before paying.
Q: What does “Non-compliant” mean if I buy the phone anyway?
The phone is not registered with PTA. Its SIM may work inside a grace period (reported as about 60 days from first local network use for personal imports), then local SIM service stops until the DIRBS tax for that IMEI is paid. The price you pay should reflect both that tax and the risk. In fact, the fair discount is bigger than the tax alone: you are also paying for the wait, the registration work, and the chance that the payable amount changes before you get round to it.
Q: Is buying a CPID phone illegal?
IMEI tampering is an offence under PECA 2016, with enforcement by the FIA, and PTA has cracked down on patched devices and the services selling them. Beyond the legal side, a CPID phone can be blocked later without warning and loses value the moment a knowledgeable buyer checks it — it is a risky purchase at any price.
Q: The seller told me the PTA tax on this phone is a fixed amount. Should I believe him?
No. The payable tax is calculated per IMEI inside DIRBS and changes with FBR schedules, so no honest fixed figure exists for a model in general. Generate the amount against that phone’s actual IMEI during registration, and do not let a verbal number decide the deal.
