You can use Regular Expression (RegEx) to easily achieve that.

<?php 
$number="786-899-677";

// Checks if $phone begins with 555
if(preg_match("/^555/",$number)>0){
    echo "Valid Phone Number!";
}else{
    echo "Invalid Phone Number!";
}
?>

PCRE RegEx Pattern

public function checkNumber(Request $request){
    $number = $request->get('phone');
    if(preg_match("/^555/",$number)>0){
        return ['valid' => true, 'phone' => $number, "left" => ["total"=> 1, "free" => 1, "paid" => 0]];
    }else{
        return ['valid' => false, 'phone' => $number, "left" => ["total"=> 1, "free" => 1, "paid" => 0]];
    }
}
