Twilio Lookups API is Not Returning Carrier Data for Canadian Phone Numbers

As of May 2018, Twilio is no longer able to provide all users carrier or portability details about Canadian phone numbers via the Lookup API. Per the Canadian Local Number Portability Consortium (CLNPC -, Twilio customers must have a contract with the CLNPC to receive this data.

Instead of returning the appropriate data, the following attributes now return null via Lookup API and Twilio Console:

  • mobile_network_code
  • name
  • type

How to request this data

In order to gain access to this data, you must first apply for approval with the CLNPC. Please contact our Support team to request access to Canadian carrier data in the Lookup API. We will respond with the required documentation, and then submit your completed application to the CLNPC.

Notice: Please note that the contract has an annual fee that has to be paid to CLNPC.
