Custom Sender ID

Custom Sender ID

When sending SMS and Text Messages via a 3rd party provider such as GReminders, the phone number the message comes from is important.

Because 3rd party systems cannot “impersonate” or “spoof” your own mobile number, GReminders sends from a Pool of numbers it owns, OR you can get your dedicated number. Read more here.

This works well for the United States and Canada.

In OTHER countries OTHER than the US or Canada, GReminders has dedicated numbers it sends from. However certain countries only support “SenderID”.

Note: US or Canada DO NOT support Custom Sender ID.

SenderID is a unique name that shows where the text message is “from”. It could represent your Brand or Product name for example. It is typically up to 11 characters long and can contain numbers and letters.

A lot of this depends on the country you are sending to.

There are tradeoffs to sending via a SenderID.

The pros are it can reinforce your Brand and its generally clear who the message came from.

The cons are that you cannot REPLY to a message sent from a SenderID. This means that you will need to use Confirmation/Reschedule Links to get responses.

Below is a list of countries that support Custom Sender IDs. Some require registration, some do not. Please inquire with [email protected] about the country you are sending to and what the specific requirements are.
