Applying for Your SMS/MMS Sender Number

As countries, regions, and local carriers implement stricter SMS regulations to protect consumers, compliance is essential to ensure successful message delivery.

To meet these requirements, SmartPush requires merchants to apply for a sender number for certain countries or regions, depending on where their SMS recipients are located.

This article explains the supported countries or regions, when a sender number is required, how to apply for one, and what additional information you may need to submit to improve approval success rates.

Country or Region Availability and Applicability

SmartPush currently supports SMS/MMS services in the 17 countries or regions listed below. If your contacts are located outside these areas, SMS sending will not be available.

For certain countries or regions, applying for a sender number is mandatory. Countries are divided into three sender number groups:

Group 1: North America (Random number assigned) - supports both SMS and MMS
Group 2: Custom Alphanumeric Sender ID (3–11 characters) - supports SMS only
Group 3: No Sender Number Required - supports SMS only

You only need to apply once per group, and the approved sender number can be used across all countries within that same group.

For example:

If you apply for Group 1, the assigned number can be used in both the United States and Canada.
If your recipients are located in countries across multiple groups, you must apply separately for each applicable group.

If your recipients are located in Group 3 countries, no application is required. SmartPush will send SMS messages as usual.

Sender Number Groups

You only need to apply once per group, and the approved sender number can be used across all countries within that same group.

Group	Country Code	Countries	Message Types
Group 1: North America (TFN)	+1	United States, Canada	SMS & MMS
Group 2: Custom Alphanumeric Sender ID	+49, +353, +39, +81, +64, +34, +44	Germany, Ireland, Italy, Japan, New Zealand, Spain, United Kingdom	SMS only
Group 3: No Sender Number Required	Various	Australia, France, Hong Kong, Malaysia, Mexico, Netherlands, Singapore, Taiwan	SMS only

Before You Apply: SMS Top-up Requirements

Before submitting your sender number application, you must complete an SMS top-up. Applications cannot be processed without a valid top-up.

Notes:

The US$1 SMS quota included in your subscription plan does not count as a valid top-up.
The minimum top-up amount is US$20.
If you enter an amount below US$20, the system will prevent submission and display a warning message.

Follow the steps below to complete your SMS top-up:

In SmartPush, navigate to Settings > Subscription Plan.
Under My plan, click SMS recharge > Top up. To check SMS rates before topping up, click View SMS pricing list to review the latest pricing for supported countries or regions.

On the SMS top-up page, you can view your current remaining SMS quota and the available top-up options. Select a preset amount or enter a custom amount (minimum US$20), then click Top up to proceed.

Note: At the bottom of the page, you can use the SMS top-up calculation tool to estimate sending costs before launching campaigns. Select a country/region and enter the number of messages to view the estimated SMS fee.

On the Purchase SMS quota page, review the amount and select a payment method. If no card is saved, click Add card and pay to enter your card details. Then click Pay now to complete the payment.

Once the payment is successfully processed, your SMS balance will be updated automatically. You can return to Subscription Plan to verify your updated SMS quota.

Applying for Your Sender Number

SmartPush streamlines the sender number registration process. Follow the steps below to submit your application:

In SmartPush, go to Settings > Activity Settings from the left navigation menu.
Scroll to the SMS/MMS compliance section, locate the SMS/MMS Sender ID management card, and click Register SMS/MMS number.

In the pop-up window, select one or more country groups and enter your sender ID (applicable to Group 2 only).

Note: If you select Group 2 (which includes the UK, New Zealand, Ireland, Germany, Italy, Japan, and Spain), you must enter your desired Sender ID before proceeding. The ID must meet the following requirements:

Length: 3–11 characters
Supported characters: Letters and numbers (case-sensitive)
Allowed symbols: Spaces, hyphens (-), and underscores (_)
Recommendation: Use an ID that reflects your brand name for better recognition

Enter the required company information, including the company name, official website, contact person, phone number, and address. After completing the form, click Submit.

After submission, your application status will be displayed in the admin panel. Once approved, your sender number will appear and become available for use.

Uploading Supporting Images (Required for All Applications)

To improve your application approval rate and speed up the review process, you are now required to upload supporting images when submitting your sender number application. These images help carriers verify your business and brand.

Attachment 1: SMS Opt-in Screenshot (Required)

Upload at least 1 screenshot (maximum 3 screenshots) showing that your website includes an SMS opt-in mechanism, demonstrating that customers consent to receive marketing SMS/MMS messages from you.

Your screenshot should clearly show:

A mobile phone number input field on your website or pop-up form
A checkbox or consent statement confirming the customer agrees to receive SMS/MMS marketing messages
A reference to your Privacy Policy or Terms of Service

Note: We recommend collecting customers' phone numbers through a pop-up subscription form. For setup instructions, refer to the "Pop-up Form" article.

Attachment 2: Brand-Company Relationship Proof (Optional but Recommended)

Upload up to 3 screenshots that demonstrate the relationship between your brand name and your registered legal company name. This is particularly important if your brand name differs from your legal company name.

Examples of acceptable proof include:

A screenshot of your website's Terms of Service or Privacy Policy that references both your brand name and your company name.
A screenshot of your business registration document showing both names.
Any official document or webpage that clearly links your brand name to your legal entity.

For example: If your brand name is "SmartPush" and your registered company name is "Starling Labs", you would need to provide a document that shows both names are associated with the same business, such as a Terms of Service page that states "SmartPush is a product of Starling Labs."

Note: Submitting this proof upfront significantly reduces the chances of your application being rejected due to a perceived mismatch between your brand and company name.

Additional Requirements for Group 1 (United States & Canada)

When applying for a sender number for Group 1 (United States and Canada), your website must demonstrate compliance with customer data collection and SMS/MMS marketing regulations. These requirements apply to both SMS and MMS sending.

To improve approval success, ensure the following requirements are met:

Mobile Number Registration

Your website should provide a mobile phone registration method.

This helps demonstrate that:

Users voluntarily register on your website.
Users consent to receive SMS messages.

Users acknowledge your privacy policy before submission.

Your website must include a clearly accessible Privacy Policy link. To increase approval rates for U.S. and Canada applications, your privacy policy should:

Data Protection Statement

Your privacy policy should clearly state:

How personal information collected for SMS communications is used.
That customer data will not be sold, rented, or shared with third parties for marketing purposes.
That any sharing of data is limited to service fulfillment or legal obligations.

If your website does not currently have a privacy policy, you may use the generator tool to create one: https://getthru.github.io/10dlcpolicygen/

Terms Acceptance

If your website includes a contact page, registration page, or login/sign-up form, users must be required to manually check a box to confirm agreement to your website terms, Privacy Policy, and SMS/MMS communications.

SMS Opt-Out Instructions

Your privacy policy must clearly explain how customers can unsubscribe from SMS messages.

It should specify:

The method customers can use to opt out (e.g., replying with specific keywords).
That opt-out requests will stop future SMS communications.

Clear opt-out instructions are required for U.S. and Canada sender number approval.

Terms Acceptance and Contact Information

If your website includes:

A contact page
A registration page
A login or sign-up form

You must ensure that users manually check a box to confirm agreement to:

Your website terms
Your privacy policy
SMS communications (if applicable)

This consent mechanism is required when collecting customer information.
