Key takeaways
- A virtual card is an issuance format, not a separate product from the Brex Card.
- Vendor-locked numbers are the main control: the card only works with one merchant.
- Subscriptions and media spend are the highest-value use cases.
- Single-use cards reduce exposure to untrusted or one-off merchants.
- Virtual cards add work if every purchase gets a new number with no naming convention.
What a virtual card is
A virtual card is a tokenised card number issued inside the same commercial programme as physical and employee cards. It has its own PAN, its own limit and, often, its own merchant lock. It does not create a second credit relationship.
Where virtual cards genuinely help
- Recurring software and cloud vendors, each on its own number.
- Advertising platforms where spend can spike without a hard ceiling.
- Agencies and contractors who should never hold a physical company card.
- One-off purchases with merchants you will not use again.
See the guide virtual cards for subscriptions for operating detail.
Where they just add administration
If every coffee and taxi gets a new virtual number, you have replaced reimbursement chaos with issuance chaos. Use employee cards for person-level spend and virtual cards for vendor-level spend. Name cards after the vendor, not the requestor.
