Credit Card Validation for UK cards

[Anon]

Can anyone tell me how I can find out valid prefix ranges for the following UK credit cards.

Visa Delta, Switch and Solo.

By prefix ranges I mean the first four digits of the card number. (e.g. Visa is between 4000 and 4999 inclusive).

Don't worry I'm not up to any underhand dealings, but just trying to improve a credit card validation routine. All the routines I can find in the scripting sites are I think American in origin and don't deal with the above cards.

Many thanks in advance.

Well a validation routine will work out if the card is valid no matter where in the world it's from. All card nnumbers are generated using the same formula.

To get those that are specific to UK based card producers you would probably have to approach Visa, Mastercard, Switch etc.

Thanks for the advice, but I am already aware of how to validate the number and I know it's the same worldwide.

As I said in my original note I just wondered if anyone knew what the 4 digit prefix ranges were for the Solo, Visa Delta and Switch cards. This is so I can put a little extra validation in to ensure the user selects the correct card type (i.e. the one that matches his number). I know the prefix ranges for Amex, Visa, Mastercard, JCB, Diner's Club etc. just not for the three mentioned above.

The problem with Solo, Switch and Delta is that they are not credit cards, but debit cards, which require an authorisation with the bank for money transactions, so just running a formula on the number won't tell you if it's good or bad.

I've no idea how upto date this is, but we use an online/offline/batched authorisation software.

This is a list of the card prefixes and their types.

Hope it is of some use.

Hi Chrber,

could you please send me how to validate the number of switch and solo cards. Would help me a lot.

[Anon]

wow, that was useful.

just one more thing....

i've got the regexp for amx, mastercard, visa and solo - has anyone got the regexp to validate a switch? it seems that switch can be 16, 18 or 19 chars long (maybe 15 or 17, but i havent come across any) and start with loads of different prefixes.

i dont know how up-to-date this list is, or whether my regexps work outside the uk. if anyone has got any more info, the credit card companies are bastards and wont tell me anything.

Here are some Regexp filters for UK Cards

MasterCard = "^{(?🙁?:[5][1-5])(?:\d{14}))$"}
Visa = "^{(?🙁?:[4])(?:\d{12}|\d{15}))$"}
AmericanExpress = "^{(?🙁?:[3][4|7])(?:\d{13}))$"}
DinersClub = "^{(?🙁?:3)(?:\d{11,12}))$"}
Discover = "^{(?🙁?:6011)(?:\d{12}))$"}
EnRoute = "^{(?🙁?:2)(?:\d{11}))$"}
JCB = "^{(?🙁?🙁?:2131|1800)(?:\d{11}))$|(?🙁?:3)(?:\d{15})))$"}
Switch/Solo = "^{(?🙁?🙁?:5641)(?:\d{12}))$|(?🙁?:6)(?:\d{15}|\d{17}|\d{18}))$|(?🙁?:4903|4905|4911|4936)(?:\d{12}|\d{14}|\d{15})))$"}

[Anon]

Hmmm.

That's the regexp for a Halifax Switch. Not switch cards in general.
