so my goal here is to shed some light on generating numbers. ive been in the business for 5 or 6 years now and i can tell you i have made probably more than a million dollars over time with just generated numbers. so im going to go through some of the different avenues you can take when generating numbers. this is going to be a multi part post as there is alot to cover and i might not be as high as i am now so i may decide to quit typing and continue later. so lets keep the unnessecary comments at a zero. and if you would like to contribute any information or bins to share or whatever hit me up on my DM just for the sake of keeping this thread easy to read and keep the informatioin all contained nicely...of course i will not try to take credit for anything else someone trys to bring to the table so just know that you will be cited as the reference of any information you provide , that is unless youd rather be anonymous.

chapter 1 - Unicorn Bins
--------------------------------


people say its a myth and you cant generate track 2 information. but the people who say this shit are the ones who just believe what they are told and run with it. ive been messing with these kinds of bins for about a year or so so ill just try do give as much information on the subject as possible. so basically what i think it comes down to is the card issuers failing to validate discretionary data. SOMETIMES (not always) this happens alot more when a bank is being bought out by another bank and therefore having to integrate that banks bin portfolio to their systems. somewhere in this mess track 2 does not get validated for a period of time and you can generate valid live numbers and swipe them instore. some bins are just vulnerable like this without being bought by another bank.

BUT......its not always that easy. there are different formulas to this that work and wont work. its different with each and every bin and you really have to test what works. im going to list a couple of the formulas that ive had work in the past and some that were given to me by other people. (algos is the term used in the past but this is not an algorithm)

-formula 1-
;4444333322221111=?
;4444333322221111?
just straight up card number only. 16 digits then the equals sign then question mark.
or even no equal sign has worked. ive found this to work with alot of retail gift cards and private label bins.

-formula 2-
;4444333322221111=yymm?
card number and expiration only. this will work at any hotel front desk when checking in. with any bin. it doesnt matter. hotels only extract card number and expiration when putting your card on file. that is all they are required to have by industry standards. rental car agencies in some states follow this standard also, but not all states and cities because of how bad the carding has become in the past couple of years.

ive had normal bins work instore like this before also. a good place to test bins for this is on a square merchant account...or a soda machine. but if you have the square account i feel like that is more accurate because they wont decline you for no reason like soda machines will sometimes.

201 bins that are vulnerable like this will swipe as 101s because there is no service code anyways.

-formula 3-
;4444333322221111=YYMMSSS?

same as above except written with service code because some banks will check up to service code but nothing after that. alot of bins will work for tap n pay like this.
also have heard of amex bins doing good like this

-formula 4-
;4444333322221111=YYMMSSS0000000000000?

all zero discretionary data. sometimes 13 zeroes, sometimes 10 zeroes sometimes a specific amount of zeroes. because sometimes a bank will not validate the data but will check the length of the data they recieve.

retail store credit cards from comenity bank will usually have this formula. with a 4912 as the expiration date which is a industry standard for a card that doesnt expire. also alot of retail gift cards will work like this.

regular bank bins will work sometimes on swipe or tap also. test your bins! you never know!


.......... TO BE CONTINUED
