Frequently asked questions
Is it safe to check card or bank numbers here?+
Checks run in your browser using standard format algorithms (like Luhn for cards) — nothing you type is transmitted or stored.
Do validators confirm an account really exists?+
They verify the format and checksum are valid. They do not contact banks or providers, so they cannot confirm ownership or balance.
Are the UPBIP validators free?+
Yes — every tool is free to start. Basic features are free to use, and upgrading to Pro unlocks premium options and higher limits.
Do I need to install any software?+
No. Everything runs in your browser on any device — desktop and mobile apps are coming.
