Sender IDs¶

This page explains what SMS Sender IDs are, how alphanumeric Sender IDs work, and what applies when a country does not support them.

What Is a Sender ID¶

A Sender ID is what appears in place of a phone number when a donor receives an SMS from Evergiving. Using an alphanumeric Sender ID (e.g., OXFAM, UNICEF) gives your messages a branded, recognisable appearance.

Alphanumeric Sender IDs¶

In supported countries, you can send SMS from an alphanumeric Sender ID. To request this, email support@evergiving.com.

A valid alphanumeric Sender ID must:

Be 3–11 Latin characters
Contain no spaces or special characters
Include at least one letter — it cannot consist of numbers only
Clearly identify the sender

Example

A charity named "Feed the Future" might use FEEDFUTR as their Sender ID. A name like 12345678 would not be valid as it contains only numbers.

Countries Without Alphanumeric Sender ID Support¶

Not all countries allow alphanumeric Sender IDs. For those countries, you will need an SMS-capable phone number registered to your account instead. Some regions require paperwork to purchase these numbers, though there are exceptions — for example, SMS-capable numbers with a United States country code can usually be obtained without additional paperwork.

See the full list of countries without alphanumeric Sender ID support.

Australian Requirements¶

If you send SMS to donors in Australia, additional registration requirements apply from 1 July 2026. See Australian Sender ID Requirements.
