A free, browseable view of the FDIC's Summary of Deposits — the official as-of-June-30 snapshot every FDIC-insured institution files annually. The data shows every physical bank branch in the United States: where it sits, how much it holds in deposits, and what institution runs it.
Source: FDIC SOD API at banks.data.fdic.gov, filtered to YEAR=2025 (the latest published snapshot as of mid-2026). Each year's data covers branches and deposits as they stood on June 30. The 2026 snapshot will be released in early 2027 and is not yet incorporated here.
Only FDIC-insured depository institutions: commercial banks, savings banks, savings associations. Credit unions are regulated by NCUA and not included. Online-only banks typically report a single HQ branch even if they have millions of customers; this dataset reflects physical branch presence, not customer count.
Money-center deposits. A single branch in lower Manhattan can hold tens of billions in deposits — most of it from corporate accounts, not local retail. When you see a county's "average deposits per branch" wildly skew upward, this is usually the cause.
FDIC cert vs brand. Several consumer brand names may roll up to one FDIC certificate — what looks like one institution might operate under multiple brands locally.
Branch service types. SOD includes drive-throughs, retail offices, and limited-service facilities — some of which a customer would never recognize as a "branch."
