As we know sender ID is a special name or specific set of digits shown above the text messages representing the company or brand sending you. Hence, you can select a campaign name, company name, brand name, or even digits instead of texts receiving from traditional system-generated standard mobile numbers. The main advantage of using a unique sender ID is that customers recognize the company or brand at once from where the message is coming from. Sender ID is actually a number masking technique by which you can display a customized name or number on the recipient’s mobile phones. Sender ID consists of only six characters following the rules of TRAI (Telecom Regulatory Authority of India). It has become possible to send such SMS which doesn’t need a written response in return by using Sender ID as it doesn’t provide a reply option. So it’s the responsibility of the sender to provide all obvious pieces of information in the text so that clients/customers easily opt out. This would be considered as a practicing organization’s best codes of ethics with each send. Sender Id or header may be of two type’s i.e Promotional and Transactional. Sender Id or header consists of strictly 6 characters neither more nor less than 6. Promotional header or sender ID is numeric i.e consists of 6 digits or numbers from 0 to 9. However, transactional headers comprises of alphabets only. Before creating a sender ID on the Bulk2SMS portal you have to create a header on DLT. The same header or sender ID would be used to send bulk SMS through any company. Each entity can create up to 20 headers including both promotional and transactional headers. While creating headers on the DLT platform one thing should be kept in mind that your header/ sender ID should resemble your organization/brand details and KYC document uploaded.
