**Short answer:** In Uruguay, sender ID requirements are set by the mobile operators (Antel and Tigo Uruguay), with URSEC as regulator. Approval typically takes 5–10 business days. Alphanumeric IDs work only on some networks. OmniChannels.ai handles the filing across 3 operators and confirms current rules during onboarding.

## How to register your sender ID in Uruguay through OmniChannels.ai

1. **Choose and check your sender ID:** Pick a sender ID that matches your brand: Latin letters, up to 11 characters. Test it in the free sender ID checker first.
2. **Send us your company details and use case:** Tell us the legal entity, brand and what each sender ID will send (OTP, transactional or promotional). We confirm which supporting documents are currently needed.
3. **We file with the operators:** We prepare and submit the application. Current process in Uruguay: BroadNet confirms the current requirements during onboarding.
4. **Approval and test messages:** Approval typically takes 5–10 business days. Once approved we send test messages on Antel, Tigo Uruguay and Claro Uruguay and check the sender ID displays correctly.
5. **Go live:** Send through the REST API, SMPP or campaigns. Schedule promotional sends for the recipient's local daytime. Opt-out handling is applied to every promotional message.

## Common reasons a sender ID is rejected in Uruguay

- Too long: sender IDs here are up to 11 characters.
- Generic words instead of a brand, such as INFO, SMS, OTP, ALERT: regulators usually refuse them.
- Arabic, accented or other non-Latin letters: this market lists Latin letters only.
- Spaces or symbols such as _ & ! ( ): many operators strip or refuse them; use a hyphen or nothing.
- Expecting the alphanumeric ID on every network: some networks replace it with a numeric sender.
