**Short answer:** Yes. Sender ID registration is required in Canada (short codes: application to txt.ca, carried only if at least two separately owned carriers agree; long-code requirements confirmed during onboarding). Approval typically takes 3–6 weeks (short codes, after txt.ca approval). Alphanumeric IDs are not used. OmniChannels.ai handles the filing across 3 operators and confirms current rules during onboarding.
