Hi!<\/p>\n

There’s a service that validates the credit card number and returns the metadata.<\/p>\n

The requisition is via http and returns a json. Just like this:<\/p>\n

curl -H \"Accept-Version: 3\"<\/span> \"https:\/\/lookup.binlist.net\/45717360\"<\/span>\r\n<\/code> {\r\n  \"number<\/span>\": {\r\n    \"length<\/span>\": 16<\/span>,\r\n    \"luhn<\/span>\": true<\/span>\r\n  }<\/span>,\r\n  \"scheme<\/span>\": \"visa\"<\/span><\/span>,\r\n  \"type<\/span>\": \"debit\"<\/span><\/span>,\r\n  \"brand<\/span>\": \"Visa\/Dankort\"<\/span><\/span>,\r\n  \"prepaid<\/span>\": false<\/span><\/span>,\r\n  \"country<\/span>\": {\r\n    \"numeric<\/span>\": \"208\"<\/span>,\r\n    \"alpha2<\/span>\": \"DK\"<\/span>,\r\n    \"name<\/span>\": \"Denmark\"<\/span>,\r\n    \"emoji<\/span>\": \"🇩🇰\"<\/span>,\r\n    \"currency<\/span>\": \"DKK\"<\/span>,\r\n    \"latitude<\/span>\": 56<\/span>,\r\n    \"longitude<\/span>\": 10<\/span>\r\n  }<\/span>,\r\n  \"bank<\/span>\": {\r\n    \"name<\/span>\": \"Jyske Bank\"<\/span>,\r\n    \"url<\/span>\": \"www.jyskebank.dk\"<\/span>,\r\n    \"phone<\/span>\": \"+4589893300\"<\/span>,\r\n    \"city<\/span>\": \"Hj\u00f8rring\"<\/span>\r\n  }\r\n<\/span>}\r\n<\/code><\/pre>\n
But if you want regex for the most common credit card brands, check below.<\/p>\n
\n
\u00a0\u00a0\u00a0\u00a0const elo = \/((((636368)|(438935)|(504175)|(451416)|(636297)))[0-9]{4}$)|(((5067)|(4576)|(4011))[0-9]{8}$)$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const visa = \/^4[0-9]{12}(?:[0-9]{3})$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const master = \/^5[1-5][0-9]{14}$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const amex = \/^3[47][0-9]{13}$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const diners = \/^3(?:0[0-5]|[68][0-9])[0-9]{11}$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const discover = \/^6(?:011|5[0-9]{2})[0-9]{12}$\/;<\/div>\n
\u00a0\u00a0\u00a0\u00a0const jcb = \/^(?:2131|1800|35\\d{3})\\d{11}$\/;<\/div>\n
<\/div>\n
That’s it!<\/div>\n<\/div>\n\n
