It will not show the carrier for any US or canadian phone number, but seems to be working for other countries.

Same thing on my end. Property Carrier is null. I really only need the carrier info.

{
“Carrier”:null,
“Country”:“United States”,
“International”:"+1 216-658-8633",
“Line Type”:“FIXED LINE OR MOBILE”,
“Local Time”:“13:14:05”,
“Location”:“Ohio”,
“National”:"(216) 658-8633",
“Owner”:null,
“Views count”:“1”
}

{
“Carrier”: null,
“Country”: “United States”,
“International”: “+”,
“Line Type”: “FIXED LINE OR MOBILE”,
“Local Time”: “18:46:46”,
“Location”: “Philadelphia”,
“National”: “() -”,
“Owner”: null,
“Views count”: “1”
}

this is the response i get without the carrier info
