- Account scope notes
- Coastal1 states Zelle is available through the mobile app and online banking.
These figures are informational guidelines from our research, not a guarantee that the same limits apply to every Coastal1 Credit Unioncustomer. Zelle availability, sending limits, and receiving limits may vary by institution, account, account type, recipient, customer relationship, security controls, and other factors. Check Supply is a separate mailed-check payment option for larger payments that do not fit within Zelle's per-transfer, daily, weekly, or monthly caps.
Use Check Supply to send payments that do not fit Zelle's availability or transaction limits.
