Atlantic Union Bank is a Virginia state-chartered commercial bank with roots going back to 1902, and the principal banking subsidiary of Atlantic Union Bankshares Corporation (NYSE: AUB), a Richmond, Virginia bank holding company regulated under the Bank Holding Company Act of 1956. It is the largest regional bank headquartered in Virginia, with roughly $37 billion in assets and a branch network across Virginia, Maryland, and North Carolina, offering consumer and business checking, savings, lending, mortgages, credit cards, and wealth management. Like most US regional banks, Atlantic Union Bank operates under the voluntary, fragmented US open-finance landscape rather than a mandated open-banking regime: it publishes no first-party public developer portal or documented public API. Consumer-permissioned account and transaction data is reached indirectly through third-party data aggregators (Plaid, Finicity by Mastercard, MX, Teller) as surfaced by aggregator coverage directories, and no direct FDX-conformant data-access endpoint, Akoya participation, or published CFPB Section 1033 posture was found. This is an identity-only, aggregator-only record with no first-party API surface.
