The Central Bank of Nigeria (CBN) is the country’s apex monetary authority, responsible for currency issuance, regulation of banks, and managing Nigeria’s fiscal stability. Its headquarters in Garki, Abuja, faces the National Assembly complex and neighboring government ministries. Visitors must schedule appointments for Tuesday or Thursday visits—public services include currency exchange queries, regulatory complaints, and financial policy information. The main phone line serves general enquiries, whistleblowing, and consumer complaints.
