Does Plivo support alphanumeric sender ID for SMS?

Plivo supports the use of alphanumeric sender IDs, but you must whitelist your account by contacting Plivo support to enable this feature. Your request should include the sender ID you wish to use, the destination countries you intend to reach, and your specific use case.

When we receive a request, Plivo checks the alphanumeric sender ID to ensure that all communication originating from Plivo is legitimate and in no way facilitates malicious activities such as social engineering, phishing, or vishing.

We verify the legitimacy of your business as it applies to the sender ID you wish to use. In some cases, we may request an official authorization from your organization’s legal department verifying the use of the requested sender ID. If your sender ID is based on a specific product or service that your company provides, we may seek specific information to establish this association.

In addition to Plivo’s restrictions on the use of alphanumeric sender IDs, country-specific restrictions may also apply. In some countries, alphanumeric sender IDs must be preapproved by local regulatory bodies. For those countries, Plivo will facilitate the approval process.

The whitelisting process can take up to three business days if approval from local carriers and regulatory bodies is not required. If you need approval from local carriers and regulatory bodies, that may take up to eight weeks.

Sender IDs are not supported in the US and Canada.
