A valid number is simply a number that conforms to a validation algorithm they use check digits like we saw with UPC Barcodes.Īn active number is a card number that conforms to this algorithm and is currently issued to a customer. I know what you’re thinking, “How can I generate a credit card number, isn’t that something only the credit card company can do?”Ĭredit card numbers are generated based on a formula. But, before you know if it’s a newspaper you enjoy, you may want to test drive their free trial and a generated credit card number can help you cut the strings and keep you safe from fake sites looking to capture your personal info. There are lots of great websites out there that require subscriptions and I think you should pay for and support the ones you use and enjoy. Then you’ll probably forget about it until you see it again next month. They’re betting against you - hoping you’ll forget to cancel your subscription so they can get some money out of you for at least one month, maybe a couple months if it’s only a few bucks and you’re too busy to cancel at the moment you notice the charge. That’s because free things are rarely ever free and that’s especially true of free trials.Ĭompanies frequently offer “free” trials in exchange for your billing info.

Just like you may use a junk email address to sign up for special offers, you may want a junk credit card number too. First of all, I don’t want anyone to get the wrong idea although the credit card numbers you generate are valid, they’re not active and aren’t for making (fraudulent) purchases.
