Australia SMS setup

Official country setup guidance from the MerchantWire SMS app documentation.

Australia scope

Select Australia under Settings → General before choosing the Twilio Messaging Service. MerchantWire SMS uses one domestic Australian two-way numeric sender so customers can reply to order texts.

Sender requirements

Use one Australian SMS-capable long-code number in the selected Messaging Service.
MerchantWire rejects alphanumeric sender IDs because they are one-way and cannot support MerchantWire reply handling.
MerchantWire rejects short codes in this release.
Twilio currently supports domestic Australian long-code SMS and two-way SMS.

Twilio also requires Australian alphanumeric sender IDs to be registered, but that path is outside MerchantWire SMS.

Customer consent and identification

MerchantWire uses an affirmative, unchecked cart opt-in. Transactional messages can include the Shopify business name at the beginning of the message. Keep that identity setting enabled for customer clarity and review the current Australian requirements for your use case.

STOP, START, and HELP

Keep Twilio Advanced Opt-Out enabled and configure the automatic replies using the customer-facing store identity and support contact. Run the MerchantWire STOP → START → HELP verification before activation.
