Is Sender ID pre‑registration required?

In some countries, you are required to register your Sender IDs to ensure successful delivery.

Sender ID registrations can take anywhere from one business day to several weeks, depending on the approval process of the local mobile operators.

Once the operator approves your Sender ID, it’s important to follow all local rules and regulations to prevent the Sender ID from being replaced or modified.

Please note: Even after registration, the Sender ID may not always appear on the recipient’s handset exactly as it was submitted.

Some countries mandate that all alphanumeric Sender IDs be registered before any messages can be delivered.

For details on which countries require Sender ID pre‑registration, please refer to the Global Sender ID Support section.

Note: SMS Sender ID regulations may change at any time based on updates from local operators.
