Understanding Sender IDs in Tanzania

The Power of a Brand Name

Messages sent from a branded sender ID like "SAKURA" have a 40% higher open rate than those from unknown numbers like +255 7XX... A Sender ID is your digital signature on every message.

Types of Sender IDs

• Alphanumeric — Your brand name (e.g., SAKURA, MYSHOP). Max 11 characters. Requires TCRA approval.
• Numeric — A phone number (e.g., +255712345678). No approval needed but lower trust.
• Short Code — A 4-6 digit number. Enterprise only, highest trust level.

TCRA Rules and Guidelines

• Length: Maximum 11 characters
• Content: Must relate to your business name. Generic names like "promo" or "alert" will be rejected
• Characters: Letters, numbers, and spaces only. No special characters (&, @, #)
• Approval Time: 3-5 business days (network operator dependent)
