Text Message Length
U.S. Carriers are standardized and all text messages are 160 characters (including spaces) in length. When sending a text message to a recipient in the U.S. with more than 160 characters, the SMS Notify! API will automatically split the message into two or more messages for delivery.
Canadian Carriers vary from 136 to 160 characters (including spaces) in length. CDYNE sends to Canada the same way as the U.S. To ensure complete message delivery, CDYNE advises that your application only send messages to Canadian recipients in 136 character increments. If the message is longer than 136 characters, the best practice is to split the message on your application side at the 136 character mark to avoid data loss that may occur from Canadian Carriers that truncate anything over 136 or 140 characters.
