Zelle at Frost Bank.
Frost Bank supports Zelle for eligible customers. Zelle can be useful for bank-to-bank transfers, but Frost Bankcontrols the account eligibility rules and transaction limits for its customers. When a payment is larger than Zelle's practical limits, Check Supply lets you send a real check instead.
Frost Bank supports Zelle
Check Supply shows Frost Bank as Zelle-supported in the latest support data. Enroll through Frost Bank's own Zelle page or online banking flow to confirm eligibility before sending money.
Zelle limit guidance
Use these figures as researched guidelines, then confirm the current cap inside Frost Bank's online banking or mobile app before sending. If the payment exceeds Frost Bank's Zelle limit, use Check Supply to mail a check for the larger amount instead.
- Max capacity notes
- Official Frost Zelle page says users can send and request payments as needed and that limits are variable.
- Account scope notes
- Zelle is available in the Frost App and Frost Online Banking for eligible personal and business checking accounts.
These figures are informational guidelines from our research, not a guarantee that the same limits apply to every Frost Bankcustomer. 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.
