Regular expression for MIR card number?

Question

JavaScript

Hello. Help me write a regular expression, please.

I'm trying to determine if this is a map of the world by the first digits

if (num.match(/^(5[1-5]|222[1-9]|22[3-9]|2[3-6]|27[01]|2720)[0-9]{0,}$/)) {

return  alert('MasterCard');

} else if (num.match(/^4[0-9]{0,}$/) || num.match(/^4\d{12}/)) {

return alert('Visa');

} else if (num.match(/^(5[06789]|6)[0-9]{0,}$/) || num.match(/^4\d{12}/)) {

return alert('Maestro');

It is necessary for the MIR map, which starts (as Google said) with 2200 and 2204. How to write a regular season?
