We have had some reports that Canadian numbers used as caller id, whether it be the caller id that is set or a local id, show up on some contact's phones as an International/Russian number.
Phoneburner sends numbers in E.164 format, which is the industry standard. That format is +1XXXXXXXXXX. We discovered that some carriers in Canada drop the 1, but keep the +. As a result, the caller ID of +1780xxxxxxx becomes just +780XXXXXXX, for example, +7 is the country code for Russia, so they are displaying Russia for the caller ID.
Given that each carrier determines how caller ID is shown, it's not possible to know which carriers are using the E.164 format, and which are not.
Since it is the industry standard, that is what Phoneburner will continue to use. We received the first report of this on local ID in October 2020. Since we didn't hear any reports of it prior to then, it's possible some Canadian carriers recently made a change that is causing this. But again, there is no way for us to know which ones. We are sorry for any inconvenience this may cause.
