Sender ID Guide
The name your recipients see instead of a phone number, and how to get yours approved.
What is a Sender ID?
A Sender ID is the “From” name that appears on an SMS instead of a random phone number. For example, a message from Techieszon arrives as if Techieszon sent it, not an unfamiliar number. It's the first thing a recipient sees, and it's a major factor in whether they trust and open the message.
The rules
- Up to 11 characters
- Letters and numbers only, no spaces or symbols
- Should clearly identify who's sending the message
How approval works
- 1. Request a Sender ID from your dashboard.
- 2. It's reviewed by our team, not an automated filter.
- 3. You get an email the instant it's approved or rejected, with a reason if declined.
- 4. Approved Sender IDs are ready to use immediately on any send.
Frequently asked
How long does approval take?
It's reviewed by a person, not a bot, so it varies, but most requests are decided quickly. You'll get an email the moment a decision is made.
What if my Sender ID is rejected?
You'll see the reason directly in your dashboard and by email. You can submit a new request with an adjusted name at any time.
Can I use a phone number as my Sender ID instead?
Yes, replies-enabled phone numbers are supported as an alternative to a branded name, depending on your use case.
Can I have more than one Sender ID?
Yes, you can request as many as you need. Useful if you run campaigns for more than one brand or department.
