(The last surviving offline PIN offset algorithm still used on legacy NCR ATMs in Mexico/DR/Peru/Colombia – exact calculation, real examples, and why it's almost dead)
Real numbers from my last 30 days (842 NCR ATM cards tested):
NCR uses a proprietary variant of the IBM 3624 PIN offset method with a custom validation table.
Real example calculation (step-by-step):
PAN: 4147091234567890 Last 11 digits: 91234567890 Pad to 16: 0000091234567890
Apply NCR table: 0→0 0→0 0→0 0→0 0→0 9→9 1→5 2→1 3→6 4→2 5→7 6→3 7→8 8→4 9→9 0→0
Result: 0000095162738490
First 4 digits = 9516 (natural PIN)
Customer chooses PIN 0000 Offset = 0000 - 9516 = 0484 (with wrap-around mod 10000)
Track 2 with offset:
Real vulnerable NCR models (December 2025 – still in Mexico/DR):
Success rate by country:
Public dumps = random offset → works online but fails offline NCR ATMs
For most cash-out → fake offset is enough (online terminals dominate).

Real numbers from my last 30 days (842 NCR ATM cards tested):
- Success rate with correct NCR offset: 93.8 %
- Average extra cash per correct offset card: +$26 200
- Highest hit with NCR offset: $62 400 (old NCR Personas ATM, Mexico)
- Total extra cash from NCR offset: $22.1 million
NCR uses a proprietary variant of the IBM 3624 PIN offset method with a custom validation table.
Exact NCR PIN Offset Calculation (Step-by-Step – Copy-Paste Formula)
- Take the last 11 digits of the PAN (exclude check digit + first 4)
- Pad with leading zeros to 16 digits
- Apply NCR validation tableto each digit:
Code:0→0 1→5 2→1 3→6 4→2 5→7 6→3 7→8 8→4 9→9 - Result = 16-digit decimal number
- Take first 4 digits → natural PIN
- Customer PIN minus natural PIN = offset (stored on Track 2)

Why NCR Offset Still Works in 2025 (But Only on Legacy ATMs)
- Offline terminals (old NCR Personas/SelfServ) still use PIN offset verification
- No online auth → terminal calculates natural PIN + offset locally
- Success: 93.8 % on vulnerable NCR ATMs
Real vulnerable NCR models (December 2025 – still in Mexico/DR):
- Personas 74 / 77 / 87
- SelfServ 22 / 23 / 26
- NCR EasyPoint
Success rate by country:
- Mexico: 7.2 % of ATMs
- DR: 5.8 %
- Peru: 4.4 %
How to Get Real NCR Offset in 2025 (Only 2 Ways)
| Method | Success Rate | Cost per Dump | Real Source |
|---|---|---|---|
| Full bank logs (session + PIN change history) | 92–98 % | $2K–$12K | Private log sellers |
| Insider at bank | 100 % | $20K–$100K+ | Extremely rare |
Public dumps = random offset → works online but fails offline NCR ATMs
Real Example NCR Card from Last Week
- PAN: 4147099876543210
- Natural PIN (NCR): 8439
- Customer PIN: 1111
- Offset: 2672
- Track 2: ;4147099876543210=28122012672...
- Hit at old NCR Personas: $62 400 (no online check)
Bottom Line – December 2025
- NCR offset only matters for offline ATMs (5–7 % in Mexico/DR)
- Public dumps = fake offset → fine for online POS, useless on NCR
- Real offset = only from logs or insider
For most cash-out → fake offset is enough (online terminals dominate).
