SMS Code Provisioning Guidelines
Use a custom alphanumeric code with an international long code set up for one-way sending. Manage opt-outs with a web link or customer preference center. Alphanumeric codes must be associated with the brand, enterprise, product, or service. These codes can include only alphanumeric characters. You can use a minimum of 3 spaces to a maximum of 11 spaces. Advanced registration for both marketing and transactional sends require a letter printed on corporate letterhead that is signed, dated, and rubber-stamped. Incomplete or erroneous documentation causes delays in the registration process.
Restricted Content
You’re responsible for complying with local rules and regulations. To ensure compliance, familiarize yourself with the legislation of the local market. Failure to comply can result in service suspension, cancellation, and potential fines. Bulgaria generally forbids content related, but not limited to, adult and gambling products and services.
