Masked Card Services: How They Work and How to Choose One

Masked card services allow you to use a temporary or alternate card number as opposed to sharing your real credit card number during checkout.
Credit card masking is useful for privacy-conscious shoppers, people who may be affected by a data breach, as well as international users, subscription managers, and companies that manage employee payments.
The best service on this front depends on a number of factors, including spending limits, pricing, funding method, card type, refund handling, the ability to lock or cancel cards, and country access.
Halocard is a very strong fit for international users who need a US-issued virtual credit cards, flexible online payments, and broad US merchant acceptance.

A masked card service is ideal because it creates a replacement payment card number that hides your real payment details when online shopping. This is a guide designed for people comparing providers, not for those who need a basic explainer. If you want safer online shopping, more control over making payments online, and fewer exposed credit card details, then the real question is which service fits your use case.

How does Credit Card Masking work?

A masked card service provides you with alternate card details for online purchases. When you shop online, instead of typing in your real credit card number, expiration date, and CVV code into a website, you simply use a generated details that connect back to your real credit card, debit card, prepaid balance, or funded account.

This provides an added layer of security because the merchant doesn't receive your real card information. This means that if a retailer suffers a data breach, the exposed credit card information or debit card information may be easier to limit, close, or replace. Most services use one or more of the following card types.

Merchant-locked cards that work only with one merchant after the first transaction.
Single-use cards are designed for individual purchases and stop working after one purchase.
Spend-limited cards that let you set limits by transaction, month, year, or total amount.

These can all help reduce unwanted renewals, over-billing, and fraudulent charges.

What to Look For in a Masked Card Service

There are various important features to pay attention to when searching for a masked card service that fits your use case.

Pricing

Always check pricing and see if the service is free, paid monthly, billed yearly, or tied to some kind of annual fee. You'll also want to check fees associated with top-ups, foreign transactions, and individual cards.

Card Type

Next, always check the card type, as some providers issue virtual credit cards, some virtual debit cards, and some gift cards. Remember that a debit or prepaid setup may not be accepted everywhere a normal credit card works.

Spend Controls

Always look for virtual cards that provide you with the ability to pause cards, set limits, close cards, and create cards for small accounts.

Funding Source

Pay attention to the funding source as well. Some services connect to your bank account, some use a debit card number, some pull from an existing line of credit, some are secured credit cards that do not require a line of credit, and some require funding by loading through a wallet or other means first.

Apps and Extensions

Browser extensions make checkout much more convenient, while a single app with a digital wallet can help with Google Pay, Apple Pay, and other mobile purchases.

Refund Handling

Before making purchases, always check if refunds return to your original card, wallet balance, or service account.

Country Availability

Some virtual card providers are US-only, whereas others support users around the world. Those that may support more users around the world may also have stricter identity checks during the verification process. For instance, Halocard supports users in 144 countries and just requires a basic identity verification check.

The Main Masked Card Services in 2026

Here are the top masked card services in 2026.

Halocard Virtual Cards for Online Payments

Halocard is the best option for international users who need a US-issued virtual card for subscriptions, US platform access, and safe online transactions. It's made for people who need credit card details that work across more US merchants than many local prepaid options.

Pricing starts at $12/month or $120/year for the Essential plan, which includes 12 virtual cards. Plus is $29/month or $290/year for 40 virtual cards, while Teams is $59/month or $590/year for 60 virtual cards. Card loads start at $100, and debit or credit card loads carry a 5% fee. Stablecoin funding is free.

The biggest feature of Halocard is that it is a US-issued card with broad acceptance and availability, all without needing to be a US resident or having a US SSN. That said, it's not totally free, but it does make sense if acceptance, privacy, accessibility, and control are worth paying for.

Privacy.com Privacy Card With Spending Limits

Privacy.com is a great option for US users who want a simple privacy card for safe online shopping. It allows users to create merchant-locked or single-use cards, add spending limits, or closed cards quickly if something looks off.

Pricing starts with a free personal plan, which includes up to 12 cards per month. There are paid plans which raise the card limit and add features such as notes, card sharing, and higher monthly card creation.

The standout feature is that it has strong control for repeat purchases and subscriptions. However, the downside is that it's not readily available, as privacy.com is only available for US users, so international shoppers will likely not be able to sign up.

Revolut Virtual Debit Card and Digital Wallet Use

Revolut is an ideal choice for those who already use Revolut and want virtual debit cards inside a single app. It allows you to use virtual cards for online purchases, and in some markets, add cards to a digital wallet for mobile payments.

The biggest standout feature here is convenience, as you can manage cards, balances, controls, and purchases all in the same app. The downside here is availability, card limits, plan pricing, and that features vary by market.

Capital One Eno Credit Card Number Masking

Capital One Eno is an ideal choice for eligible Capital One credit card customers who want to mask their actual credit card details when shopping online. Capital One Eno generates virtual numbers linked to your Capital One account.

The best feature here is that it works inside your existing card relationship, so your charges still appear on your normal account. The downside is of course that you already need to be eligible for a Capital One card from that credit card company. Keep in mind, this is not a standalone masked card service.

Citi Virtual Account Numbers for Credit Card Users

If you're a current Citibank card holder who needs a virtual card that is tied to your account, then Citibank virtual account numbers may be the best option for you. To help protect your real credit card number during online transactions.

The biggest benefit here is that this feature comes from the existing card issuer, meaning that everything stays inside the same card relationship. That said, availability and controls change by card and account, so users should confirm their feature set before relying on it.

IronVest Masked Card Number for Privacy

IronVest is best for people who are privacy focused. It helps mask details, emails, and more, which matters when you need broad privacy tools and secure storage for personal data.

The biggest benefit here is of course that it features an all-in-one privacy approach. However, the drawback is that the masked card features are generally tied to paid plans and feel less direct than a dedicated virtual card app.

Which Masked Card Service Is Right for You?

If you're looking for US platform access from abroad, strong acceptance and availability, and great privacy features, Halocard is likely your best option. However, if your main goal is simply managing subscriptions, Privacy.com is a fine option. If you're looking for a free privacy layer, Capital One or Revolut work well too.
