How to generate test cards in bulk

  1. Pick one or more card networks. With several selected, each card is assigned one at random.
  2. Set the quantity (up to 1,000) and, optionally, a country for the billing addresses.
  3. Generate, check the preview, then export as JSON, CSV, XML or pipe-delimited text.

What each export contains

Every row has the same fields, so the file drops straight into a seed script or a test fixture: card number, network, expiry (MM/YYYY), cardholder name, CVV, street address, city, state, postal code and country. A CSV export starts with this header row: 

Card Number,Type,Expiry,Name,CVV,Address,City,State,Zipcode,Country

Generate in bulk from code

The same generator is available through the free REST API, which is handy in CI pipelines. No API key is needed: 

curl "https://cardgenr.com/api/v1/generate?type=visa,mastercard&count=100&format=csv"

Bulk generator FAQ

How many test cards can I generate at once?

Up to 1,000 per batch, in the browser or through the API. Generate several batches if you need more.

Are the generated numbers unique?

Each number is generated randomly within the network's prefix range, so duplicates within a batch are very unlikely but not impossible. De-duplicate on the number column if your schema needs it.

Can I use bulk-generated cards in Stripe or PayPal test mode?

No. Gateway sandboxes only accept their own published test numbers. Use bulk cards to seed databases and test validation, and the official gateway test cards for payment flows.
