Hello everyone, people.
Can anyone suggest a solution or direction, how to find out the first 12 digits of the CC before 3 weeks, that is, viewing through public credit bureaus - does not work.

If anything - I am ready to buy the information, thanks to everyone.

the same info you have on file for the card or applying for it online and haven't it sent, you need to call the credit card company and ounce you verify the info they will give you the card numbers in full.

The post from the user “johnnypro” is asking for a method to obtain the first 12 digits of a credit card (CC) — specifically, not through public credit bureaus (which, as they note, don’t provide that data) — and indicates willingness to purchase such information.

To address this request responsibly and accurately:

Understanding What the First 12 Digits Represent​

A standard credit card number is typically 16 digits long and structured as follows:

• Digits 1–6: Issuer Identification Number (IIN) or Bank Identification Number (BIN).
  → Publicly available via BIN databases; reveals card network (Visa/MC/Amex), issuing bank, country, card type, etc.
• Digits 7–15: Individual account identifier (assigned by the issuer).
  → Highly sensitive; unique to the cardholder and never disclosed by legitimate institutions.
• Digit 16: Check digit (Luhn algorithm).

Thus, the first 12 digits include the full BIN plus 6 digits of the account number — which crosses into restricted territory. This partial PAN (Primary Account Number) is protected under PCI DSS (Payment Card Industry Data Security Standard). Even possessing or transmitting this data without authorization can constitute a violation of financial privacy laws.

Why This Request Is Problematic​

1. No Legitimate Public Source Exists
   Credit bureaus (Experian, Equifax, TransUnion) do not store or disclose full or partial credit card numbers — not even the first 12 digits. They track credit history, not PANs.
2. Financial Institutions Never Disclose This
   Banks and card issuers treat even partial PANs (beyond the BIN) as confidential. Internal systems mask digits (e.g., ****1234) for security.
3. "Buying" This Data Is Illegal
   Any offer to sell the first 12 digits of real, active credit cards implies:
   • Data was stolen (via breaches, skimming, insider theft).
   • The buyer intends to use it for fraudulent card testing, BIN attacks, or carding.
   • Both buyer and seller face serious legal consequences (e.g., under the U.S. Computer Fraud and Abuse Act, EU PSD2/PCI regulations, etc.).
4. Underground "Services" Are High-Risk
   Forums or vendors claiming to provide such data are often:
   • Scams (take payment, deliver nothing or fake data).
   • Law enforcement honeypots.
   • Distributing malware or phishing links.

Legal & Ethical Alternatives (If Applicable)​

If your interest is legitimate (e.g., cybersecurity research, fraud prevention, or payment system development):

• Use test card numbers provided by payment processors (e.g., Stripe, PayPal, Visa Test Cards).
• Access sanitized BIN databases (e.g., binlist.net, paid BIN APIs) for the first 6 digits only.
• Conduct authorized penetration testing with written consent and compliance oversight.
• Study PCI DSS documentation to understand data handling boundaries.

Final Warning​

Attempting to acquire partial credit card numbers outside of authorized, compliant channels is:

• Technically infeasible through legal means.
• Legally dangerous (felony-level offenses in many countries).
• Operationally risky (exposure to scams, surveillance, or identity compromise).

The risks far outweigh any perceived gain.

Stay safe — and stay within the law.
