OnePay customers may need help with a deposit account, debit card, direct deposit, missing transfer, disputed transaction, OnePay Wallet, OnePay Advance, OnePay Later payment, OnePay Credit Card, credit reporting, account login, or account closure.

OnePay Is a Fintech Company, Not a Bank
OnePay is a financial technology company.
Banking services through OnePay are provided by:
- Coastal Community Bank, Member FDIC, or
- Lead Bank, Member FDIC
The bank associated with a particular deposit account can be viewed inside the OnePay app.
To check:
- Open OnePay.
- Select Banking.
- Open the Settings icon.
- Scroll to the account information showing the bank that provides the banking services.
Qualifying deposits are eligible for FDIC pass-through insurance subject to applicable requirements and limits.
This distinction is important for:
- Deposit insurance
- Routing numbers
- Wire instructions
- Deposit-account agreements
- Regulatory complaints
OnePay Was Previously Called One
Customers may encounter older references to One, ONE Finance, or One Cash in account records, app reviews, payment descriptions, and older help information.
The company changed the consumer brand from One to OnePay on March 21, 2025.
Product names also changed.
Examples include:
- One Pay: now OnePay Wallet
- One Cash: now Banking through OnePay
- One Debit Card: now OnePay Debit Card
- Loans: now OnePay Loans
Older references to One or ONE Finance do not necessarily indicate a different account provider.
OnePay Checking and Savings Help
Banking through OnePay includes a deposit account with Checking and Savings sections.
Savings pockets and goals may appear separately in the app, but they are part of the OnePay deposit-account relationship.
Customers can use OnePay for services including:
- Direct deposit
- ACH transfers
- Debit-card purchases
- Cash deposits at participating retailers
- ATM withdrawals
- Bill Pay
- One-to-One transfers
- Eligible mobile check deposits
- Wire deposits
OnePay does not currently offer joint deposit accounts or the ability to add an authorized signer to an existing deposit account.
OnePay Routing Number
There is not one routing number that every OnePay customer should copy from a third-party website.
OnePay deposit accounts can be provided through either Coastal Community Bank or Lead Bank.
Use the routing number displayed for your individual account in the OnePay app.
To find the correct account information:
- Open the OnePay app.
- Select Banking.
- Open the appropriate Checking information.
- View the account and routing details.
Use the exact numbers displayed for the account when setting up:
- Direct deposit
- ACH transfers
- Bill payments
- External bank connections
- Wire transfers
OnePay Direct Deposit Help
Direct deposit can be set up through the OnePay app or through an employer or payroll provider.
OnePay currently instructs customers setting up direct deposit through an employer to identify:
- The account as a checking account
- The account number shown in OnePay
- The routing number shown in OnePay
An employer can require one or two payroll cycles to complete a direct-deposit change.
OnePay states that it posts qualifying direct deposits when received, which can result in funds becoming available up to approximately two days early and, for limited employers, as much as three days early.
Early availability is not guaranteed for every paycheck because timing depends on when the employer or payer sends the deposit.
Missing OnePay Direct Deposit
If a direct deposit has not arrived:
- Verify the account and routing numbers used by the employer.
- Confirm that Checking was selected as the account type.
- Ask the payroll provider when the deposit was actually sent.
- Confirm that the employee name matches the account information.
- Allow for weekends and federal holidays.
- Contact the payroll provider if two business days have passed since it says the payment was sent.
- Contact OnePay if the employer confirms the deposit was sent correctly.
OnePay cannot normally see a payroll deposit before it reaches its banking system.
OnePay Debit Card Help
Customers banking through OnePay can use a physical and virtual OnePay debit card.
Card controls in the app allow customers to:
- View card information
- Change the card PIN
- Freeze the physical card
- Freeze all cards and payments
- Request a replacement
- Track a replacement card
Lost, Stolen, or Damaged OnePay Debit Card
To replace a physical card:
- Open Checking or Savings.
- Select the card icon.
- Select Replace Card.
- Choose damaged, missing, or stolen.
- Confirm the mailing address.
- Submit the replacement request.
OnePay currently states that replacement cards generally arrive within 7 to 10 business days.
A stolen or missing card is deactivated when reported, and the replacement receives new card credentials where applicable.
If the card may simply be misplaced, use the Freeze Card control while looking for it.
How to Dispute a OnePay Transaction
Customers can file disputes directly through the OnePay app.
To submit a dispute:
- Open OnePay.
- Select Profile.
- Tap Help.
- Select File A Dispute.
- Choose the affected account and transaction type.

- Wrong transaction amount
- Duplicate charge

Customers can use the OnePay app to:
- Add an eligible card
- Remove a card
- Select a default payment card
- Review rewards offers
- Pay using the OnePay Wallet QR code where supported
OnePay Wallet is separate from the underlying bank or credit-card account attached to it.
A refund, dispute, or card-account problem may need to be handled through the institution that issued the payment card.
OnePay Advance Help
OnePay Advance is available to selected eligible customers who bank through OnePay.
Eligibility currently includes factors such as receiving at least $500 in qualifying monthly direct deposits.
When an Advance is taken, the amount is deposited into Checking.
Repayment can occur automatically from qualifying deposits into Checking.
Customers can also make a manual repayment in the app:
- Open OnePay.
- Make sure enough money is available in Checking.
- Select the Advance balance.
- Select Repay Advance.
- Enter the repayment amount.
- Confirm the payment.
An Advance is separate from OnePay’s Fee-Free Overdraft feature.
Availability, limits, and eligibility can change and are determined by OnePay rather than by Customer Service upon request.
OnePay Later Customer Service
OnePay Later is powered and serviced through Klarna and its lending partners.
Customers can review payment terms through the OnePay app:

OnePay Later After You Shop
Eligible customers banking through OnePay may also see an option to convert a recently completed purchase into a OnePay Later payment plan.
Eligibility is determined by Klarna.
Current monthly financing offers can carry APRs ranging from 9.99% to 35.99%, depending on approval and the offer presented.
A late payment can currently result in a fee of up to $7.

Credit-card approvals are determined by Synchrony Bank.
If an application is declined, OnePay currently directs applicants to Synchrony at:
Support is available 24/7.

How to Close a OnePay Account
OnePay deposit accounts cannot currently be closed simply by deleting the app.
Call 1-855-830-6200 or use in-app chat and ask Customer Service to close the deposit account.
Before closing:

OnePay Cash Sweeps
OnePay can use a Cash Sweeps program to move eligible deposits among participating FDIC-insured partner banks.
This occurs behind the scenes and does not normally change the Checking balance displayed in the app or how the customer accesses the money.
Customers who want to opt out of Cash Sweeps can contact OnePay.
OnePay states that opting out is permanent, but opting out does not by itself close the deposit account.
Contact Customer Service before opting out if you have questions about how Cash Sweeps affects your account or deposit-insurance coverage.
