TPIN is a unique ten-digit computer-generated number allocated to a taxpayer upon registration with the Zambia Revenue Authority (ZRA). It is a prerequisite for any transaction with ZRA concerning taxes be it Domestic Taxes or Customs Services. All bank account holders are also required to obtain a TPIN.

The process of TPIN registration has now been made easier because of the online registration platform available; hence one can register from the comfort of their premises. Taxpayers who have challenges with online registration can still register manually by completing a ZRA prescribed registration form. The manual form can be obtained from any of the front offices at ZRA offices or it can be downloaded from the ZRA website
