Understanding Sender IDs in SMS Messaging Across Countries
A Sender ID is the distinct name or number displayed when a recipient receives an SMS. It's like a caller ID for text messages. While some countries allow flexibility in its format, others have stringent guidelines. This article provides insights into the diverse types of Sender IDs per country and their regulations. Also, check out the Country Restriction Category for a comprehensive understanding [here].
Diving Deep into Sender ID Categories
Sender IDs aren't one-size-fits-all; they vary depending on the region or country's stipulated protocols. We’ve broadly categorized them into five primary types:
1. Dynamic Open: Sender IDs can be in Latin Alphabets and Numeric
2. Dynamic Alphabet: All Sender IDs must be in Latin Alphabets
3. Dynamic Numeric: All Sender ID must be in Numeric
4. Overwritten: In certain countries, regardless of what you choose, Sender IDs are replaced (overwritten) either by our officially registered name in that particular country or by a specific numeric code. This can range from short to long codes, and might be in local or international (E.164) format. For instance, in Niger, any Sender ID might be replaced by "SMS", while in Belgium it might become "8850". In the US, it could appear as "+14155552671".
5. Pre-Registration: This category is exclusive. Only those Sender IDs which have been pre-registered by us can be used. If not pre-registered, Sender IDs will be overwritten by a default ID.
