Yes. Plivo supports the use of alphanumeric sender IDs. You can now register and manage your Sender IDs directly through the Plivo console by submitting a compliance application. This application should include the Sender ID you want to use, the destination countries, and details about your messaging use case.
After you submit the request, Plivo reviews it to ensure that all communication originating from your account is legitimate and does not facilitate malicious activities such as social engineering, phishing, or vishing. We may verify your business credentials and, if necessary, request additional documentation—such as a letter of authorization from your organization’s legal department—to confirm your right to use a specific Sender ID. If the Sender ID represents a product or service your company offers, we may ask for information to establish this connection.
Some countries have strict regulatory requirements and may mandate preapproval of alphanumeric Sender IDs. If local carrier or regulatory approvals are needed, it can take up to eight weeks. If no approvals are required, the process typically takes a few business days.
Most customers can complete the Sender ID registration and compliance process directly through the console. Should you face exceptional circumstances, our support team is available to assist.
Please note that alphanumeric Sender IDs are currently not supported in the United States or Canada.
