After a customer came to us asking "Hey, we used to get SMS confirmations from our bank, but now we don't" we looked into things a bit. Turns out SMS messages came from this set of Canadian DIDs, a mix of Fido Communications and Rogers Wireless numbers: DID SMSes since Oct 10, 2015 +1 416-831-8764 17 +1 416-832-0534 22 +1 416-832-9571 10 +1 416-833-0513 11 +1 514-549-6142 20 +1 514-562-4790 14 +1 613-219-5798 17 +1 613-252-8695 13 +1 613-255-6723 16 +1 613-255-6948 16 +1 613-255-8743 11 +1 613-262-1558 7 +1 613-262-5338 12 +1 613-262-5944 10 +1 613-262-8114 11 +1 613-291-3026 17 +1 613-614-1453 13 +1 613-697-8730 13 +1 613-890-6922 19 +1 647-686-2308 11 +1 647-818-2312 18 24 customers receive SMS messages from one or more of these entities to either log into their account (Two Factor Authentication) or get important notifications about their business with these companies. The SMS Confirmation Messages seem to have came from multiple sources across these numbers: * GrubHub * PayPal * Singapore Airlines * Citibank * Healthcare.Gov * KrisFlyer * Facebook * TicketMaster * Square * Thumbtack They came in every now and then as one might expect. But then, after January 16, 2016, they stopped. I assume that since there were multiple entities sending outbound SMS messages from Canada numbers that there was a single service/entity behind all of those confirmation messages. I have two theories -- 1. They moved to Short Codes, which our non-wireless numbers cannot receive (thank you Incumbent wireless carriers - sarcasm dripping thank you) 2. Their DIDs got shut down for use outside of the Terms & Conditions Does anyone know anything about such a service? Why all of the SMS messages stopped on that one day?
