Zelle limit guidance

- Max capacity notes
- Official FAQ says send amount and frequency are set by each participating financial institution and customers must contact Credit Union 1 to determine send limits; it states there are no receive limits.
- Account scope notes
- Zelle is available through Credit Union 1 online banking or the mobile app for eligible enrolled accounts.
These figures are informational guidelines from our research, not a guarantee that the same limits apply to every Credit Union 1customer. 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.
