Pakistan's DIRBS system requires every mobile phone on Pakistani cellular networks to be registered with PTA. Unregistered IMEIs are progressively blocked from all network connectivity. If you bring a phone from abroad, you have exactly 30 days from the device first connecting to a Pakistani cellular network to complete registration at dirbs.pta.gov.pk and pay applicable import taxes. ## How DIRBS Works and Why It Was Implemented PTA implemented DIRBS to combat mobile phone theft (stolen phones were easily re-used on Pakistani networks), grey market imports (phones brought without paying applicable duties), and counterfeit devices with fake IMEIs. The blocking mechanism operates across all networks simultaneously — a blocked IMEI cannot get cellular connectivity on any Pakistani operator. WiFi functionality continues to work on blocked phones, but for any cellular use, registration is essential. ## PTA Tax Calculation by Phone Value Tax components on DIRBS registration: PTA registration fee (by USD value tier), customs duty (approximately 1% of PKR value), sales tax (17% on phone value plus customs duty), and Additional Income Tax (AIT) of 1% for ATL filers or 2% for non-filers. For a flagship phone worth USD 800 at Rs. 278/USD: PTA registration fee = Rs. 16,500; Customs duty (1%) = Rs. 2,224; Sales tax (17%) = Rs. 38,186; AIT for ATL filer (1%) = Rs. 2,224. Total for filer approximately Rs. 59,134. For non-filer: add Rs. 2,224 extra AIT = approximately Rs. 61,358. PTA registration fee tiers: USD up to 30 = Rs. 430; USD 31-100 = Rs. 2,550; USD 101-200 = Rs. 4,500; USD 201-350 = Rs. 8,000; USD 351-500 = Rs. 11,500; USD above 500 = Rs. 16,500. ## The 30-Day Registration Window Registration clock starts from the day the device first connects to a Pakistani cellular network. After 30 days without registration, PTA initiates blocking — you receive SMS warnings first. After the grace period expires, cellular connectivity ceases. Registration remains possible after the deadline at the same tax cost — connectivity restores within 24-72 hours of payment confirmation. ## Registration Process — Step by Step Visit dirbs.pta.gov.pk. Enter your CNIC (13-digit) and phone's IMEI (dial *#06# to display). System validates both and shows the calculated tax. Select payment method — online banking, Easypaisa, JazzCash, 1-Link ATM, or designated bank branch. After payment confirmation, registration processes within 24-72 hours with SMS confirmation. One phone per year at traveler rates per CNIC. A second device in the same year requires commercial import tax rates — significantly higher. Each adult family member can register one phone under their own CNIC at traveler rates.
