Register Your Business Alias to Avoid SMS Blockage
6 min readFactivoReviewed:
Registering your business alias is crucial to ensure effective client communication and avoid message blockages.
Why is registering your business alias important?
In today's digital landscape, maintaining seamless communication with clients is key to business success. For freelancers and small businesses relying on SMS, ensuring messages reach their destination is crucial. The CNMC has implemented a new alias registration system to combat fraud and identity spoofing in messages.
What does the new alias registration system entail?
From September 15, 2026, businesses that do not register their alias may have their SMS, MMS, and RCS messages blocked. This affects any business using a trade name, brand, or internet domain as a sender instead of a phone number. The registration links each alias to its legitimate owner, helping prevent spoofing fraud.
How does this affect freelancers?
For freelancers using SMS to confirm appointments, send promotions, or conduct commercial communications, registration is vital. Not registering the alias could disrupt communication with clients, potentially affecting customer relationships and ultimately, business revenue.
Steps to register your alias
- Visit the CNMC portal to start the registration process.
- Ensure your alias is legitimately linked to your business.
- Complete the registration before the deadline to avoid blockages.
Practical example
Imagine you are a freelancer managing a small dental clinic. You use SMS to remind patients of their appointments. If you don't register your clinic's alias, your messages could be blocked, potentially leading to missed appointments and dissatisfied clients.
