ETK Rejection via SMS

The VIA SMS RET mechanism allows service providers with a ViA package to collect ETK rejection notifications from recipients via SMS. These messages are sent to the short code 3338 (source: IYS_KISAMESAJ).

• Rejection notifications can be processed using brand IYS numbers or brand short names.

• A maximum of three brand short names can be assigned per brand.

• Short names can be managed via the İYS Web portal under Brand Short Name Management.

Request Format (For IYS Test Environment)

Recipients must send an SMS in the following format:

RET <BRAND_SHORT_NAME> SDXIYS → 3338

Example Request:
