Applying for Your SMS 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 the SMS top-up requirements before submission.

Country or Region Availability and Applicability

SmartPush currently supports SMS 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)
Group 2: Custom Alphanumeric Sender ID (3–11 characters)
Group 3: No Sender Number Required

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.

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. For details, refer to the
