How to Write a Dump Like a Pro in 2025
đ§ What Is a Dump (In Carding Terms)?
A âdumpâ is raw track data scraped from the magstripe of a credit/debit cardâusually Track 1 and/or Track 2. This data is gold for cloning cards and swiping in-store. If you donât understand the format, youâre dead on arrival.
- Track 1:Â Includes cardholder name + card number + expiration + CVV info (sometimes)
- Track 2:Â Just the essentialsâPAN, exp date, service code, discretionary data
If your goal is to physically encode and swipe, Track 2 is king. But for full emulation, both tracks matter.
đ§ž Anatomy of a Dump: Break It Down
Hereâs the blueprint. A dump ainât just random numbersâitâs got structure:
Track 1 Format
%B4111111111111111^DOE/JOHN^2512101000000000000000000000000?
Track 2 Format
;4111111111111111=25121010000000000000?
- %BÂ â Track 1 Start
- 4111âŚÂ â PAN (Card Number)
- DOE/JOHNÂ â Cardholder Name (LAST/FIRST)
- ^2512Â â Expiration Date (MMYY)
- =Â â Track 2 Separator
- 101Â â Service Code
Thatâs your playground. Now letâs write your own.
đ ď¸ How to Write a Dump (Step-by-Step)
Step 1: Grab Clean BIN Info
Use a legit BIN (Bank Identification Number). Canât stress this enough. BIN determines the format, country, and bankâif it donât match, expect chargebacks or instant declines.
- Use BIN lookup tools (e.g., BinList, Bincodes API)
- Match country + type (Visa/Mastercard, debit/credit, etc.)
Step 2: Structure the Dump Manually
If youâre not pulling from a skimmer or EMV reader, youâll write it manually. Stick to proper format:
Track 1: %B[PAN]^[SURNAME/FIRSTNAME]^[MMYY + Service Code + Filler]? Track 2: ;[PAN]=[MMYY + Service Code + Filler]?
Example:
Track 1: %B4532752023456789^DOE/JOHN^26121200000000000000000? Track 2: ;4532752023456789=26121200000000000000?
Donât make up digits randomlyâlearn how to generate valid Luhn-check PANs or get them from a BIN generator with CCV match support.
Step 3: Encode That Dump
Once your dump is clean, burn it to a blank card using a MSR606/705 writer:
- Install your encoder software (like MSR206 Tools)
- Insert blank mag card
- Paste Track 1 and Track 2 dumps
- Write to magstripe â success beep means good
If you get encoding errors, your formatâs busted. Go back, recheck spacing, special chars (^ ; = ?
) and try again.
â ď¸ Pro Dump Writing Tactics
Use Fresh Dumps Always
Recycled dumps are suicide. Use recent skimmed dumps or create yours from validated BINs and CCV combos.
Skip Track 1 If Needed
Most POS systems verify only Track 2. If encoding fails with Track 1, go with just Track 2 for quick hits.
Donât Reuse Dumps
Once burned and swiped, dump becomes hot. Never clone it againâmove on, or risk hard declines and camera footage.
Use Randomized Filler
That long line of zeros? Fill it with custom randomized digits to evade fraud detection algorithms.
