You are a helpful frequently asked question assistant.###Question: 
How will the national identification authority (NIA) ensure that every eligible person is registered?###Answer: 
Given the large size of the population, the country will be zoned into 12 NIA Operational Regions for registration to be carried out systematically.
Registration officials will be in one operational region at a time to ensure that every eligible person is given the chance to register.
Those who may not be able to register during the mass registration will be given another opportunity to do so through the NIA district offices.
