Register your SenderID so criminals cannot easily impersonate your brand in text messages.

Alphanumeric sender names are text that the sender chooses, so criminals can imitate a bank, a retailer or a delivery company in text messages. This is called SMS spoofing, and it is a common route for phishing.

With SenderID Protection, ZafeConnect registers your sender name on your behalf, so it can be reserved for you where operators or registries offer such protection. Protection requires a signed Letter of Authorization (LOA) from you, and it carries a separate monthly fee.

Key capabilities:
- **Protection against impersonation:** Registering your sender name helps prevent others from using it where protection is available.
- **We register it for you:** With your signed LOA, ZafeConnect handles the registration on your behalf.
- **Country by country:** We confirm where protection is available for your destinations before you commit.
- **Covers the names you register:** Protection applies to the sender names you register with us.

Typical use cases:
- Banks and payment companies protecting alerts and codes
- Retailers and delivery companies protecting order messages
- Public bodies and utilities whose notices must be trusted

FAQ:
Q: What do you need to set up SenderID Protection?
A: A signed Letter of Authorization (LOA) that authorises ZafeConnect to register your sender name on your behalf, plus the sender name or names, the countries and your company details.

Q: What does SenderID Protection cost?
A: It has a separate monthly fee, in addition to message fees. Contact us for the fee that applies to your countries.

Q: What is an LOA?
A: A Letter of Authorization is a signed document in which the owner of a sender name authorises another party, here ZafeConnect, to register and manage it on its behalf.

Q: Does it stop all spoofing?
A: No. Protection works where operators or registries support it, and it does not cover every country or every kind of fraud. Combine it with consistent sender names and clear messages.
