What is NIN?

The National Identification Number (NIN) is a unique 11-digit identifier issued by the National Identity Management Commission (NIMC) to every Nigerian citizen and legal resident. It serves as a primary means of identity verification across government and private sector services.

​
How it Works

Send a POST request to /api/v1/kyc/nin with the individual’s NIN in the request body. The API returns verified biographical data, contact information, a base64-encoded passport photo, and next-of-kin details from the NIMC registry. 
curl --location 'https://sigmacdd.sabipay.com/api/v1/kyc/nin' \
--header 'apiKey: {{apiKey}}' \
--header 'apiSecret: {{apiSecret}}' \
--header 'Content-Type: application/json' \
--data '{
    "idNumber": "98864126516"
}'
