The Unique Identification Number (UIN) in Cameroon

Visit Unique Identification Number (UIN) is now one of the most important instruments of tax and administrative reform in Cameroon. Established by the Direction Générale des Impôts (DGI), it aims to guarantee reliable and permanent identification of taxpayers, whether individuals or corporate bodies. By centralizing information and standardizing procedures, the NIU has become an essential tool in relations between the State, citizens and economic players.

1. Definition and nature of NIU

Visit NIU is a code alphanumeric allocated exclusively to each taxpayer. Its specificity lies in its unique and permanentOnce issued, it cannot be shared or modified, even in the event of a change of activity or location.
It enables the tax authorities to accurately track the obligations of each individual or company, secure transactions and reduce the risk of fraud. In this sense, the NIU is not just an administrative number, but a veritable governance tool.

2. Creation context and objectives

Prior to the introduction of the NIU, Cameroon's tax authorities were faced with major difficulties: multiple identification numbers, no centralized database, frequent duplication and lack of traceability. These shortcomings encouraged tax evasion and complicated taxpayers' procedures. 

The NIU has several objectives

a) Individuals

Anyone carrying out an income-generating activity in Cameroon must have a NIU. This includes : 

  • traders and retailers ;
  • craftsmen and service providers;
  • liberal professions (lawyers, doctors, architects, etc.);
  • employees subject to specific tax obligations.

b) Legal entities

  • commercial companies and sole proprietorships ;
  • associations and NGOs ;
  • cooperatives ;
  • public or semi-public establishments engaged in economic activity.
