Why Update Your HAZECO Reference Number?

On January 6, 2023, Hazara Electric Supply Company (HAZECO) officially separated from PESCO. As part of this transition, your old PESCO reference number was updated, specifically the middle 5-digit Sub Division (SDIV) code, which now reflects the new HAZECO system.
Example:

  • Old PESCO Reference: 08-26735-0121483
  • New HAZECO Reference: 08-27224-0121483
