Locating your phone's IMEI number is the first step before PTA registration, status verification, or various other phone-related administrative tasks. The IMEI (International Mobile Equipment Identity) is a 15-digit unique identifier permanently assigned to each mobile phone — like a serial number that identifies the specific device globally. Most phones have multiple ways to access the IMEI: through phone settings, dialing a special code, examining the physical phone, or checking the original packaging. Knowing where to find IMEI matters because all PTA interactions require it — registration application, status verification, dispute resolution, and various other processes.
The universal method — *#06# dialing code
The most reliable IMEI lookup method works across virtually all phones:
- Open your phone's dialer/phone app (where you make calls)
- Dial *#06# (asterisk hash zero six hash)
- Press call/dial button
- IMEI number(s) display on screen immediately
- Note all IMEI numbers shown (dual SIM phones typically have two)
- The dialing doesn't make a call — it triggers display of system information
- Works on Android, iPhone, and most other mobile platforms
Finding IMEI in phone settings
Alternative method through device settings:
Android phones — typically: Settings → About Phone → Status → IMEI (or similar path). Specific menu structure varies by manufacturer (Samsung's One UI, Xiaomi's MIUI, Vivo's FunTouch all have slightly different paths but similar destination).
iPhone — typically: Settings → General → About → scroll to IMEI. iPhone shows IMEI in About section. iPhones support dial-code (*#06#) too.
Dual SIM phones — both IMEIs typically shown together. Some interfaces list "IMEI 1" and "IMEI 2" separately; others show both numbers in sequence.
Tablet devices — similar paths to phones if the device has cellular capability. WiFi-only tablets typically don't have IMEI (using MAC address instead).
The settings approach takes more steps than dial code but provides additional information (device specifications, model number, etc.) useful in some contexts.
Physical phone IMEI locations
IMEI is also printed on physical phone in various locations:
Battery compartment (older phones) — phones with removable batteries had IMEI sticker behind battery. Modern non-removable battery phones typically don't have this.
SIM tray (modern phones) — many modern phones print IMEI on the SIM tray itself. Eject the SIM tray (paperclip or SIM eject tool); the IMEI may be visible on the tray or in the SIM slot.
Back of phone or original packaging — some phones have IMEI laser-engraved on back or printed on labels. Original phone box typically has IMEI sticker.
Authorized service center records — service center can look up IMEI through serial number or other phone identifiers if other methods fail.
For consumers needing IMEI without phone access — original purchase invoice or warranty card from authorized dealer typically includes IMEI. Verify when buying that IMEI on documentation matches actual phone.
Understanding the IMEI format
IMEI numbers follow specific structure:
15 digits total — example: 35-209900-176148-1
First 6 digits (TAC) — Type Approval Code identifying phone manufacturer and model. Different brands and models have different TAC ranges.
Next 2 digits — Final assembly code (where the device was assembled).
Next 6 digits — Serial number unique to the specific device.
Last digit — Checksum digit for validation. Calculated from previous 14 digits using Luhn algorithm.
For dual SIM phones — typically IMEI 1 (SIM 1 slot) ends in the actual checksum digit while IMEI 2 (SIM 2 slot) is incremented from IMEI 1. The two IMEIs are usually sequential or differ in last few digits.
For consumers wanting to verify their IMEI is plausibly genuine — verify it has exactly 15 digits, all numeric. Less than 15 digits or non-numeric characters suggest tampered or misread IMEI.
Dual SIM phones — both IMEIs matter
Modern Pakistani phones almost universally support dual SIM operation with two IMEIs:
Why two IMEIs — each SIM slot operates independently, requires its own identifier for network registration. The two IMEIs enable simultaneous operation on two different mobile networks.
Registration implications — both IMEIs need PTA registration if you want to use both SIM slots. Some users only use one slot and register only that IMEI; using only one SIM in dual SIM phone.
Cost implications — PTA tax typically applies per registered IMEI. Registering both IMEIs costs double the tax compared to registering one. For consumers primarily using one SIM, register only the primary IMEI to save costs.
Future flexibility — even if only using one SIM currently, both IMEIs being registered future-proofs the phone for dual SIM use. Some consumers register both for convenience despite higher initial cost.
For verification — dual SIM phones need both IMEIs verified separately. Each IMEI has its own approval status; one approved, one not is possible if only one was registered.
Common IMEI lookup issues
- 🚩 Confusing IMEI with serial number — they're different identifiers
- 🚩 Recording only one IMEI on dual SIM phones — note both
- 🚩 Misreading IMEI digits — verify by multiple methods
- 🚩 Trusting IMEI on packaging without verifying matches phone
- 🚩 Using fake IMEIs from counterfeit phones — invalid checksum
- 🚩 Believing IMEI changes over time — it's permanent
- 🚩 Confusing IMEI with phone number — completely different identifiers
What if you can't access the phone
Scenarios where direct phone access isn't possible:
Phone is broken or won't turn on — IMEI may be physically visible on SIM tray, back of phone, or original packaging. Authorized service centers can sometimes recover IMEI from hardware.
Phone is stolen or lost — original purchase invoice and warranty documents typically include IMEI. For phones registered with PTA, the IMEI may be retrievable through PTA records (for legitimate ownership verification).
Phone belongs to someone else — request they share IMEI through *#06# verification in your presence. Don't accept IMEI claims without verification.
Phone with broken display — IMEI from physical phone (SIM tray, etc.) or original documentation. Service centers can recover from undamaged components.
For consumers buying phones without seeing them physically (online purchase from distant seller) — request the seller to send photographs of IMEI displayed via *#06#, plus IMEI from SIM tray, plus IMEI from packaging. Multiple sources confirming same IMEI provides reasonable confidence.
Using IMEI for various administrative tasks
IMEI serves multiple purposes beyond PTA registration:
PTA registration application — fundamental input for the registration process.
PTA approval verification — used to check current status through any verification method.
Theft recovery — police investigations use IMEI to track stolen phones. The IMEI tied to network connections enables tracking by mobile operators.
Insurance claims — phone insurance policies typically reference IMEI for claim verification.
Warranty service — authorized service centers use IMEI to verify warranty status and process claims.
Resale documentation — providing IMEI to buyers enables their verification of registration status before purchase.
International unlock services — phones locked to specific carriers often unlocked using IMEI-based services.
Frequently Asked Questions
Dual SIM functionality. Each SIM slot in dual SIM phones operates independently and requires its own IMEI for network registration. The two IMEIs are typically sequential or differ in last few digits. Single SIM phones have only one IMEI. For consumers using one SIM only in dual SIM phone, the secondary IMEI still exists but isn't actively used for network operations. PTA registration is per-IMEI, so dual SIM use requires registering both.
IMEI is permanently assigned at manufacturing and shouldn't change during the phone's legitimate use. The hardware IMEI is fixed. However: factory reset doesn't change IMEI (it's hardware-level, not software-level); some illegal services claim to change IMEI but this damages legal status and may be technical fraud; legitimate repair situations preserve IMEI even when major components are replaced. If your IMEI appears to have changed, suspect tampering or counterfeiting.
Yes — each SIM slot has its own IMEI. Typically labeled as IMEI 1 (SIM 1) and IMEI 2 (SIM 2). The phone uses different IMEI for each SIM's network communication. For PTA purposes, register the IMEI(s) corresponding to SIM(s) you intend to use. Single-SIM users in dual-SIM phones can register just primary IMEI; dual-SIM users register both.
IMEI identifies the device for network operations (15-digit standardized international format). Serial number is the manufacturer's tracking identifier (varies by manufacturer in format and length). Both unique to specific device but used differently — IMEI by mobile networks and PTA, serial by manufacturer for warranty and inventory. They're different identifiers though both unique to the device. PTA registration uses IMEI; manufacturer warranty uses serial number.
Investigate the discrepancy — multiple IMEIs in different places should be identical (for single SIM) or both legitimate (for dual SIM showing two). Differences might indicate: confusion between IMEI 1 and IMEI 2 on dual SIM (each has its own), display/labeling errors, or tampered phone. Verify by multiple methods — *#06# code, settings, physical phone — all should show same IMEI(s). Persistent discrepancies warrant investigation; possibly counterfeit or tampered phone.
Generally yes for limited purposes. IMEI verification doesn't expose personal data; it only confirms PTA approval status. Sharing IMEI with prospective buyers, family verifying registration, or service personnel for legitimate purposes is acceptable. Don't share IMEI with suspicious services claiming "premium" services or fraudsters demanding it for unclear purposes. The IMEI itself is just an identifier; legitimate verification through official channels is safe.
