I did some digging in to this issue for you and unfortunately it appears that it’s all based on how these companies are doing their checks. Some companies will actively check numbers to see what it comes back to, where others will use outdated lists, or blanket-ly block all numbers from a certain number prefix that belongs to a voip provider.

Your options would be to get a new number, or contact the individual companies that you’re having issues with and letting them whitelist your number, or give you a different means to verify yourself on their site.

Thanks for the insights. Unfortunately, it appears white listing my number is not an offered option from them at this point. I will try again but their answer from support was , “You need to contact the company that issued you the sim card on your phone.” I tend to think like you, it probably is not something Koodo can do something about.

Hi ​@mariobourassa, we’ve consulted both our Number Administration Center and our Tech Support team and, unfortunately, there’s nothing else we can do to flag the number as postpaid. The transfer is complete, the number is accurately labelled as Koodo Postpaid on our end.

Each company/service uses different data bases for their number detection and their lists may not be accurate or up to date.
