What is BVN?

The Bank Verification Number (BVN) is a unique 11-digit identifier issued by the Central Bank of Nigeria (CBN) to every bank account holder in Nigeria. It links an individual’s biometric data and personal information across all Nigerian banks.

​
How it Works

Send a POST request to /api/v1/kyc/bvn with the individual’s BVN in the request body. The API returns verified biographical data, contact information, and a base64-encoded passport photo from the BVN registry. 
curl --location 'https://sigmacdd.sabipay.com/api/v1/kyc/bvn' \
--header 'apiKey: {{apiKey}}' \
--header 'apiSecret: {{apiSecret}}' \
--header 'Content-Type: application/json' \
--data '{
    "idNumber": "22241887099"
