An SMS sender ID is a unique identifier for sending text messages. It identifies who the message was sent by so recipients know where to reply when they receive an incoming text from this number.

Through these benefits, companies can deliver better customer service and increase sales opportunities.
What’s the Maximum Length for an SMS Sender ID?
When it comes to texting, the maximum length for an SMS sender ID depends on whether you are using letters or numbers.
If you’re using alphanumeric or letter sender IDs, you’re permitted to use up to 11 characters.
On the other hand, if you’re using numbers, the sender ID can have up to 15 characters.
Why Is There Such a Small Limit on The Number of Characters Permitted in A Sender ID?
The reason there’s such a small limit on the number of characters allowed in a sender ID stems from one of the SMS standards. It has always been so.
When texting began in 1992, screen sizes were comparatively tiny, and many phones may not have had room for more than 11 characters.
What are the Various SMS restrictions on Sender IDs?
The age of wireless communication has made it difficult to regulate what was once a simple action.
Operators have quickly instituted measures in response, but the challenge is still prevalent due to the global nature of sending SMS messages on mobile phones and other devices.
Due to their inherent ability for quick responses from around the world, operators are always playing catch-up when trying to institute new restrictions or regulations that will limit how people send text messages across networks worldwide.
Some of the restrictions on sender IDs include:
1. Registered sender names only
In some countries, A2P messaging is allowed only when the user registers with the network operators.
This can make it easier to track the message back to its original sender because either the operator. Or central government agency in the destination country would have access to that information if needed.
2. Sender signature included in the text
Did you know that in some countries, the sender info must be include in the body of a message so customers can verify its validity?
This is due to country regulations where this signature serves as verification for what appears on one’s phone.
3. Sender name type restrictions
Mobile network operators vary significantly in the types of sender IDs they allow.
Some networks restrict you to using long numbers. Because they want recipients to have a simple way to contact you from an outside source, like a text or email.
Others only allow alphanumeric numbers to text so that customers can identify brands trying to reach them without getting confuse.
Finally, other states have rules whereby only short-code messages license directly by the network providers are permitted.
4. Spam filters
Mobile network operators require their clients and messaging partners to prove strong spam prevention measures.
This helps prevent repeat messages from being sent, or technical problems from arising due to spamming.
Messaging content is also closely observe and stop. If it resembled a scam message, was inappropriate, or went against local SMS regulations.
