Does a VPN or data-center IP always cause payment failure?

No definitive conclusion follows. Network and browser signals are clues, not proof of a merchant decline reason. Follow the service’s regional eligibility rules; troubleshoot VPNs, pop-ups or redirects if authentication is disrupted. Switching IPs does not establish eligibility.

What should I do if 3DS authentication fails?

Allow necessary pop-ups and redirects within the merchant and bank checkout flow, and complete the bank’s OTP or app approval there. Contact the issuer if authentication never appears or repeatedly fails. This portal does not run real 3DS or request your OTP.

Does one virtual or crypto card decline mean all such cards are unsupported?

No. Distinguish online, cross-border and recurring capabilities from merchant eligibility, then verify funds, billing and 3DS. Unknown compatibility means neither unsupported nor guaranteed acceptance. ChatGPT subscriptions and OpenAI API credit purchases are separate products.

Which billing address should I use?

Use truthful billing details matching issuer records and check merchant eligibility and card issuance region. Do not invent an address to match an IP. The tool provides consistency hints, not bank AVS; do not submit full card numbers or sensitive credentials here.

Are card numbers collected, and is payment success guaranteed?

No full card number, CVV, password or OTP is collected; diagnosis remains in the current page. Network checks may contact third-party IP / STUN services that see the public IP. The tool cannot read issuer authorization, actual 3DS results or account history and cannot guarantee success.
