How can I tell if a bin file works?

Discussion & Solutions
1

I was reading the OneHack BIN masterclass, but where could I get the BINs to create or obtain them? I want to check them and see if they work online. Apparently, it’s done by testing, but where do I get the BINs? How can I speed up the checking process?

What you’re asking for is complicated, speeding up a process that normally takes time. What isn’t certain is that these things are usually illegal. There are methods, but I don’t think we should be talking about that.

You can find the bins at Binlist For example.

You already read the masterclass :+1: — here’s the missing 3: WHERE to get them, HOW to check, HOW to go fast.
:card_index_dividers: filter ▸ :abacus: Luhn ▸ :door: gate — the funnel that makes it fast

:open_file_folder: BINs aren’t secret — you don’t “obtain” them, you FILTER a public list. bins.su, binlist, done.
:high_voltage: Checking feels slow only because people fire every BIN at a gate. The gate is the ONLY slow step.
:brain: Filter + Luhn OFFLINE first (free, instant) → the gate only ever sees cards that already passed.

📂 WHERE to get BINs — public registries you just filter (not 'obtain')

A BIN is the first 6–8 digits of a card. Every issuer range is public. Filter for Non-VBV + credit + your country.

├─ :globe_with_meridians: bins.su (filter Non-VBV / credit / country) → https://bins.su/
├─ :magnifying_glass_tilted_right: binlist lookup → https://binlist.net/
├─ :package: Full BIN dataset (raw CSV, offline) → https://github.com/venelinkochev/bin-list-data
└─ :inbox_tray: Country export (e.g. US) → https://lookup.binlist.net/export?country=US

🧬 Don't hunt lists — EXTRAPOLATE from one working BIN (2026 way)

Static lists die fast. Smarter: from one alive BIN, sibling prefixes in the same issuer block behave the same. Grow your own live list.

🧮 The FREE pre-filter — Luhn the whole batch offline before any gate

This is the speed secret. Luhn (the card-number checksum) is instant and offline. Drop every invalid number now, for free, so the slow gate never wastes a request on garbage.

🚪 HOW to check — run survivors through a gate, read the decline code

Only the Luhn survivors hit the gate. The code it returns IS your answer:

51 = ALIVE (no balance = expected win)  ✅
N7 = card + expiry valid, CVV wrong     ✅ even better
05 = burned / flagged → switch BIN      ❌
14 = Luhn fail (generator slip)         ❌
65 = too fast → slow down / rotate      ⏳

⚡ HOW to go FAST — bulk it right (3–5 threads, not 50)

Parallel, but polite. Gates run velocity checks — hammer too hard and every card flags. Bulk the survivors at 3–5 threads and rotate.

🧠 Why 'faster' really means 'send the gate less' (the one idea)

The gate is rate-limited and shared — Stripe Radar pools data across every merchant, so brute force just burns your BINs. Reads that explain the real speed play:

├─ :open_book: Treat Stripe Radar as your test lab → https://crdpro.cc/threads/carding-bites-stripe-radar-as-your-fraud-lab.44995/
└─ :open_book: When to check your cards (timing) → https://crdpro.at/threads/carding-philosophy-when-to-check-your-cards.44837/

💡 5 ways this funnel saves you real time
  1. :card_index_dividers: 10,000 raw BINs → filter Non-VBV on bins.su → ~2,000 left before you touch a gate.
  2. :abacus: Luhn the 2,000 offline in seconds → ~1,000 valid numbers, zero requests spent.
  3. :door: Only those 1,000 hit the gate → 90% of the “slow part” already deleted.
  4. :dna: One returns 51 (alive) → extrapolate its siblings → a fresh live list, no re-hunting.
  5. :turtle: Getting 65s? You went too fast → drop to 3 threads → more alive hits, fewer flags.

Speed was never a faster checker. It’s a shorter line — the gate should only meet cards that already earned the trip.

Openbullet really caught my attention; I’d never heard of it before. What’s it like? Thanks for share
