According to email marketing company MailChimp, Canadian wireless providers “began blocking Application-to-Person SMS messages,” as of November 10th.
The company says it is working with Canadian providers to resolve the issue, and in the meantime have disabled two-step logins asking for SMS authentication codes (customer 2FA discounts will remain in effect).
Here’s what @RogersHelps responded to customers affected by this issue:

MailChimp says customers looking to secure their accounts can setup Google Authentication instead within security settings.

Are you being affected this carrier blocking of two-factor SMS authentication codes? We’ve reached out to carriers for comment and will update this post when we hear back.
Thanks David
Update Nov. 13, 1:11PM PDT: A Telus spokesperson responded via email to confirm “we do not block this type of SMS”.
