Sender ID Approvals

Control which SMS sender names your customers can use, and set each customer's enforcement policy.

Why Sender IDs Matter

The sender ID is the "from" name on an SMS — and it's the biggest compliance risk in wholesale SMS, because an unchecked customer could send as a bank or brand they don't own. The sender ID system gives you control over this for your customers.

The Three Policies

Each of your customers has a sender ID policy, set from your Sender IDs page:

  • Off — any sender allowed (the default; matches historical behavior).
  • Log — any sender allowed, but unapproved ones are logged for review. Good for transition periods.
  • Strict — messages from unapproved sender IDs are rejected before sending.

The Approval Flow

  1. Your customer requests a sender ID from their portal (3–11 letters/numbers).
  2. It appears on your Sender IDs page as Pending.
  3. You approve or reject it. Approved sender IDs work immediately under any policy.

Changing Your Mind

A decision isn't final — an approved sender ID can be rejected later (e.g. if it turns out to be misused), and a rejected one can be approved after all. Your Sender IDs page always shows both actions, whichever the current status is.

The page also shows a Decided By column. Since 6X can decide on any customer's sender ID directly, not just your own decisions show here — if it says "superadmin" instead of "partner," 6X made that call for you.

💡 Tip: Move customers to Strict once their legitimate sender IDs are approved. Start new customers on Log to see what they actually use before enforcing.
