Zelle at 1NB Bank.
1NB Bank supports Zelle for eligible customers. Zelle can be useful for bank-to-bank transfers, but 1NB 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.
1NB Bank supports Zelle
Check Supply shows 1NB Bank as Zelle-supported in the latest support data. Enroll through 1NB 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 1NB Bank's online banking or mobile app before sending. If the payment exceeds 1NB Bank's Zelle limit, use Check Supply to mail a check for the larger amount instead.
- Max capacity notes
- Official services page says daily and monthly limits apply and may vary from account to account; no dollar amounts are published.
- Account scope notes
- Zelle is offered through the 1NB Bank mobile banking app or online banking account; individual sends and requests are listed as free except a stop-payment fee on a sent payment.
These figures are informational guidelines from our research, not a guarantee that the same limits apply to every 1NB 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.
