What is the difference between a header and a template?

Updated 25 October 2026 · 1 min read

Quick answer

A header (sender ID) is the short name customers see as the sender, such as JD-BSMSIN-S. A template is the fixed message text you register, with {#var#} for the parts that change.

Header Template
What it is Sender name Message text
Example BSMSIN Dear {#var#}, your order {#var#} is shipped. - BSMSIN
Format 6 letters (service/transactional), numeric for promotional Fixed text plus {#var#}
How many Usually a few per business One per message type

What the letters around a header mean

The prefix, such as JD or VM, shows the operator and circle. The suffix -P, -S, -T or -G shows whether the message is promotional, service, transactional or government. Read SMS header meaning.

Common mistakes

  • Choosing a header that does not represent your brand. Generic words are usually rejected.
  • Linking a template to the wrong header on the DLT portal.
