What are Alphanumeric Sender IDs?
Alphanumeric Sender ID allows you to set your company name or brand as the Sender ID when sending one-way SMS messages.
You can now receive replies to messages sent from an Alphanumeric Sender ID using our "Universal Reply" feature.
Alphanumeric Sender IDs can be between 3 to 11 characters in length and support the following categories:
- Upper-case letters A-Z
- Lower-case letters a-z
- Numbers 0-9
Your ID must include at least one letter and cannot be composed only of numbers. Non-ASCII special characters and punctuation are not allowed.
To help calculate the length of your sender ID, we recommend using the Sakari SMS length calculator: https://sakari.io/sms-length-calculator/
Users must specifically opt-in to receive your messages and know how to opt out before you send your first message.
Alphanumeric Sender IDs only support one-way communication. As such, you must provide other opt-out instructions, such as contacting a Support team, calling a Support phone line, or texting another phone number or short code phone number to allow users to opt out. You can also enable the "Universal Reply" feature on your Alphanumeric Sender ID which allows users to send you a reply.
