Capital is not officially supported in Zelle
Capital is not listed as an officially supported institution in the Zelle enrollment directory based on our latest review. You can still use Check Supply to send payments from your account by mailed check instead of relying on Zelle.
The Zelle directory has several unrelated institutions with Capital in the name, including Capital One and Capital Bank, but no exact match for Capital at capital.xyz. Public information describes Capital as a fintech platform rather than a Zelle-participating bank.
Use Check Supply to send payments that do not fit Zelle's availability or transaction limits.
