Received a Mariner Finance Check in the Mail? Here’s How It Works
If you received a physical check payable to you in an envelope from Mariner Finance, this is a prescreened "live check" loan offer.
- Cashing the check binds you to a loan: Cashing or depositing the check automatically opens a formal personal loan account in your name under the APR and monthly repayment terms detailed in the attached agreement.
- Check the interest rate & terms: Pre-approved mail checks usually carry fixed APRs between 18% and 35.99%. Review the enclosed disclosure to verify term length (e.g., 24, 36, or 48 months).
- 15-Day Satisfaction Guarantee: If you cash the check and change your mind, Mariner Finance offers a 15-day window to return the full principal amount without paying interest or cancellation fees.

Critical Fine Print: Live Checks & Auto Title Collateral
1. Cashing a Mail Check Opens a Loan: Depositing a live check sent in the mail legally binds you to the credit agreement attached to the letter.
2. Vehicle Title Collateral: While online loans from $1,500 to $14,000 are often unsecured, Mariner frequently requires pledging a vehicle title (first lien on a car under 10 years old) for loans above $15,000 or lower credit tiers.
3. 15-Day Satisfaction Guarantee: If you accept a Mariner loan and change your mind, Mariner offers a 15-day window to return the principal with zero interest charges.

Frequently Asked Questions
Where do I find my Mariner Finance offer code?
Your offer code is usually printed in a bold callout box on the front page of the mailer or adjacent to the detachable application coupon. You can redeem it online at marinerfinance.com.
What happens if I cash a Mariner Finance check received in the mail?
Depositing or cashing a live mail check constitutes full acceptance of the personal loan agreement. Monthly payments will begin on the date specified in your loan disclosures.
Do I have to go to a Mariner branch in person?
Most standard loans between $1,500 and $14,000 can be completed entirely online. However, if your loan requires vehicle title verification or is outside that dollar range, you may be invited to complete closing at a local Mariner branch.
Does checking my Mariner offer code affect my credit score?
No. Redeeming your offer code online to check rates uses a soft credit inquiry. A hard credit pull only occurs when you finalize and submit the completed application.
