Atlantic Union Bank

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.

Atlantic Union Bank is profiled on the APIs.io network. Tagged areas include Financial-Services, Banking, United States, Regional Bank, and Virginia.

Atlantic Union Bank’s developer surface includes support and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/atlantic-union-bank: open an issue to ask a question, or submit a pull request to add artifacts.
