Capital One Platinum Secured Mastercard – Full Details
The previous page explained why the Capital One Platinum Secured Mastercard works well for building or rebuilding credit. This page covers eligibility, the deposit and application process, and how to reach Capital One.
Additional benefits
CreditWise monitoring
Cardholders get free access to CreditWise, which tracks TransUnion and Experian credit reports and sends alerts when something changes, useful for watching progress while building credit.
Automatic credit line reviews
Rather than requiring a manual request and a new deposit, Capital One reviews eligible secured accounts for a higher credit line automatically, typically starting around 6 months of on-time use.
Eligibility requirements
This card is designed for applicants with limited, damaged, or no credit history. The required security deposit ($49, $99, or $200 for a $200 line) is determined by Capital One based on the applicant’s profile during the application.
We recommend confirming the exact deposit required for your situation directly on Capital One’s official page.

Other common questions
What happens to my deposit if I close the account?
If the account is closed in good standing with no outstanding balance, the security deposit is generally refunded.
Can I get my deposit back without closing the card?
Yes, if the account graduates to an unsecured product after a period of responsible use, Capital One typically refunds the deposit at that point.
Does this card report to all three credit bureaus?
Secured cards from major issuers like Capital One generally report to the major credit bureaus; confirming this directly with Capital One before applying is worthwhile if that is the main goal.
Is Platinum Secured good in practice?
As a credit-building tool, it does its job with a low, flexible deposit and a clear upgrade path. It is not meant to compete with rewards cards or low-APR products.
