A code for internet and business lines
365 numbers are less common than 905 or 289 and lean towards newer carriers: in CNAC’s records Iristel, TekSavvy and Distributel are among the biggest holders, and more than half of the 365 exchanges belong to internet and VoIP providers. A 365 call is therefore often a business line or an app number.
