## How to register a SenderID: the process step by step

A SenderID lets your SMS arrive under your brand name instead of a phone number. In many countries it has to be registered first. This guide explains how the process works with ZafeConnect, and how SenderID Protection differs.

Key takeaways:
- Tell us your sender name, use case and destination countries. We check the rules for each country.
- Some countries require registration or vetting, and some restrict alphanumeric senders altogether.
- SenderID Protection needs a signed Letter of Authorization (LOA), so that we can register your sender on your behalf.
- SenderID Protection has a separate monthly fee, in addition to message fees.

### Registration versus protection

 | SenderID registration | SenderID Protection
What it does | Gets your sender name approved so you can send with it | Helps stop others from sending under your sender name
What we need from you | Sender name, use case and sample messages, destination countries, company details and any documents the country requires | The same, plus a signed Letter of Authorization (LOA)
Fees | Where a country or operator charges for registration, we tell you what applies | A separate monthly fee, in addition to message fees
Availability | Depends on the destination country | Depends on country and operator; we confirm before you commit

### The registration process

- 1. Choose your sender name: up to 11 letters and digits for SMS, ideally your brand or product name.
- 2. Tell us your countries and use case: where you send and what you send, with sample messages.
- 3. We check the local rules: whether the country requires registration, restricts alphanumeric senders or needs documents.
- 4. Provide your details: your company information, your business registration number and any documents the country requires.
- 5. We submit the registration with the relevant operators, aggregators or registries.
- 6. Approval and activation: once approved, the sender is available as an approved sender in your account and in the API.
- 7. Go live and monitor: send, follow delivery in your analytics, and tell us about changes.

### Adding SenderID Protection
SenderID Protection is set up in addition to registration, and it needs your signed authorization.
- 1. Tell us which sender names and countries to protect.
- 2. We confirm where protection is available and the monthly fee.
- 3. You sign the Letter of Authorization (LOA).
- 4. We register the sender names on your behalf.
- 5. Protection is active. The monthly fee is billed separately from your message fees.
- 6. Ongoing: tell us when you add sender names or countries so protection can be extended.

### What is a Letter of Authorization (LOA)?
A Letter of Authorization is a signed document in which the owner of a sender name authorises ZafeConnect to register and manage it on its behalf. It typically names your company, the sender name or names and the countries, and is signed by an authorised representative.

ZafeConnect needs the LOA before it can register SenderID Protection for you.

### Country rules to expect
Rules change, so we confirm them for your destinations. Examples of what you may meet:
- Some countries require sender names to be registered before use, for example India’s DLT framework and Singapore’s mandatory sender ID registry.
- Some countries restrict alphanumeric senders or do not allow them.
- Some countries run protection registries for sender names.
- Registration may need sample message templates and company documents.

### How long does it take?
Lead times depend on the country and the operators involved. Some registrations are quick, others take longer. We give you an estimate once we know your countries, so plan registration well before your launch date.

### Tips for a smooth registration

- Use one consistent sender name that matches your brand
- Have your company documents ready
- Prepare sample messages for each use case
- Register before launch, not on launch day
- Only use a sender name that you own or are authorised to use

FAQ:
Q: How long does SenderID registration take?
A: It depends on the country and operators. We give you an estimate once we know your destinations.

Q: Do I need SenderID Protection?
A: Registration lets you send under your name. Protection adds a step that helps stop others from using it. It is most valuable for brands that are targets of phishing, such as banks, retailers and delivery companies.

Q: What does the LOA do?
A: It authorises ZafeConnect to register and manage your sender name on your behalf. Without it we cannot register SenderID Protection.

Q: Is there a fee?
A: SenderID Protection has a separate monthly fee. For registration, we tell you if a country or operator charges for it. See our pricing page.
