Answer 2

Bangladeshi phone number (Citycell, Robi, Grameen Phone, Banglalink, Airtel and Teletalk operators) validation by using regular expression :

$pattern = '/(^(\+8801|8801|01|008801))[1-9]{1}(\d){8}$/';
$BangladeshiPhoneNo = "+8801840001417";

if(preg_match($pattern, $BangladeshiPhoneNo)){
    echo "It is a valid Bangladeshi phone number;
}

Answer 3

Should be pretty simple:

^(?:\+?88)?01[15-9]\d{8}$

• ^ - From start of the string
• (?:\+?88)? - optional 88, which may begin in +
• 01 - mandatory 01
• [15-9] - "1 or 5 or 6 or 7 or 8 or 9"
• \d{8} - 8 digits
• $ - end of the string

Update 2020

As BTRC approved 2 new prefixes, 013 for Grameenphone and 014 for Banglalink, updated expression for now:

^(?:\+?88)?01[13-9]\d{8}$

Answer 4

I know, that question was asked long time ago, but i assume that @G. M. Nazmul Hossain want to validate mobile number againt chosen country. I show you, how to do it with free library libphonenumber from Google. It's available for Java, C++ and Javascript, but there're also fork for PHP and, i believe, other languages.

+880 tells me that it's country code for Bangladesh. Let's try to validate example numbers with following code in Javascript:

String bdNumberStr = "8801711419556"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    //BD is default country code for Bangladesh (used for number without 880 at the begginning)
    PhoneNumber bdNumberProto = phoneUtil.parse(bdNumberStr, "BD");
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}
boolean isValid = phoneUtil.isValidNumber(bdNumberProto); // returns true

That code will handle also numbers with spaces in it (for example "880 17 11 41 95 56"), or even with 00880 at the beggininng (+ is sometimes replaced with 00).

Try it out yourself on demo page. Validates all of provided examples and even more.
