Regular expression to detect credit card flag

I need Regex to detect when the credit card flag is Hipercard, Aura and Elo.

I already own regexes for Amex, Martercard, Diners Club, Visa, Discover and JCB: 

Visa: ^4[0-9]{12}(?:[0-9]{3})
Mastercard: ^5[1-5][0-9]{14}
Amex: ^3[47][0-9]{13}
Diners Club: ^3(?:0[0-5]|[68][0-9])[0-9]{11}
Discover: ^6(?:011|5[0-9]{2})[0-9]{12}
JCB: ^(?:2131|1800|35\d{3})\d{11}

Credit card numbers follow an international standard called IEC-7812.

Basically, the first six digits of the card are the Issuer identifier number (Iin).

So, you don't need a regex, but a list of IIN with which you can check the number.

Elo: 

/^((((636368)|(438935)|(504175)|(451416)|(636297))\d{0,10})|((5067)|(4576)|(4011))\d{0,12})$/

Hipercard: 

/^(606282\d{10}(\d{3})?)|(3841\d{15})$/

For those who work with technologies based on nodejs and want a simpler way that addresses a large amount of Cards I recommend using the npm Credit Card type to identify which card flag by its number.

Use ES6 modules: 

import creditCardType from 'credit-card-type'


creditCardType(cardNumber).filter((card) => {
  return card.type
})

Carões supported:

  • visa
  • mastercard
  • american-express
  • diners-club
  • discover
  • jcb
  • unionpay
  • Master
  • mir
  • elo
  • hyper
  • hipercard
