For a virtual number tied to an existing credit-card account, Capital One is the clearest documented option—but access depends on your card and account. If you want single-use or merchant-locked numbers, Privacy offers more explicit controls, but it is a debit service funded from a linked U.S. checking account, not a credit card. The right choice depends on whether you need credit or value spending controls more.
What counts as a virtual credit card?
A virtual card number is a digital payment credential you use instead of your physical card’s underlying number for a transaction. The provider may give it its own security code and expiration date, and may let you limit where or how it can be used. Features vary: an issuer may connect a virtual number to a credit-card account, while a separate service may issue numbers funded from a bank account. Those are related tools, but they are not the same product.
Which options are worth comparing?
| Option | What it offers | Who it may suit | Important qualification |
|---|---|---|---|
| Capital One virtual card numbers (Eno) | Virtual numbers for eligible credit-card accounts; numbers can be managed or deleted in the app or on the website. | Existing Capital One cardholders who want a virtual number connected to a credit account. | Capital One says availability varies by card type and account. Check Capital One’s Eno information and virtual-card support page for eligibility and current access details. |
| Privacy.com | Virtual debit cards with single-use, merchant-locked, and category-locked controls. | U.S. users who prioritize transaction controls and are comfortable funding purchases from a linked checking account. | It is not a credit line. See Privacy’s product information and pricing page for current terms. |
| Citi | A September 2026 CNBC Select roundup names Citi Strata as its no-annual-fee pick. | Readers comparing credit cards who also want to investigate virtual-number access. | The roundup does not establish current official Citi terms for a specific card’s virtual-number feature. Verify directly with Citi before applying or relying on access. CNBC Select’s comparison. |
How to choose
- Decide whether you need credit. Capital One’s feature is associated with an eligible credit-card account. Privacy draws funds from a linked U.S. checking account, so spending with it does not use a credit line.
- Match the controls to the purchase. A single-use number can be useful for a one-off purchase; merchant-locked controls can help keep a number tied to a particular merchant. Capital One’s cited materials establish virtual-number management, while Privacy explicitly describes these control types.
- Check access before counting on it. Capital One says not every card type or account user has access. Privacy’s eligibility terms are U.S.-specific. Features and availability may change, so confirm the current terms for your account and location.
- Compare costs and rewards separately. A virtual-number feature does not by itself establish a card’s annual fee, rewards, or other account terms. Privacy’s stated transaction fees are described below; check any issuer’s current card terms for its costs and rewards.
- Consider where you will use it. The documented descriptions focus on card-number transactions, especially online use. Do not assume that a virtual number works for an in-person wallet transaction unless the provider confirms that capability.
Privacy eligibility and fees
Privacy says its service is available to U.S. citizens or legal residents who are at least 18 and have a checking account at a U.S. bank or credit union. Its Personal plan lists no fee for domestic purchases and a 3% foreign transaction fee, with a $0.50 minimum. These are the provider’s stated terms; confirm current pricing and cardholder terms before using the service. Privacy says it earns interchange from merchants.
Privacy’s official materials say its cards are issued by Patriot Bank, N.A., Member FDIC, under Mastercard and Visa licenses. A Privacy support article dated December 2023 said its cards worked online where U.S. debit or credit cards were accepted and that physical cards and virtual wallet cards were not offered at that time. Because that wallet information is older, check Privacy’s current support materials rather than treating it as a current limitation. Privacy’s support article.

What is the best choice?
If you already hold an eligible Capital One credit card and want virtual numbers connected to that account, start by checking Capital One’s availability for your card. If you specifically want single-use or merchant-locked numbers and are comfortable paying from a linked U.S. checking account, compare Privacy’s current terms. Citi may be worth investigating as a credit-card option, but the cited secondary roundup alone is not enough to confirm its current virtual-number eligibility or feature details.
