Hi @Seller_fy2h8hFN5NczD

Connor from Amazon here, thanks for your question.

We do not block any countries from receiving OTP, there can be multiple factors why you don't receive the text message and there is no work around right now that we can provide as this is a required safety mechanism.

Here are some of the common solutions and can help with the OTP issues:

1. Blocked Numbers or Short Codes

Ensure that the phone number or short codes from Amazon have not been blocked in your device's contact list or settings. If short codes are blocked, contact your carrier to unblock them.

2. Carrier Issues

Some carriers may not support text messages, or there may be restrictions preventing SMS delivery. Please verify with your carrier if there are any blocks in place. If your carrier has a block on receiving SMS, such as a carrier or account-level restriction, you will need to contact them to lift the block.

3. Network Coverage

If your mobile device is out of network coverage when the SMS is sent, it may not be received. Please ensure your phone is within a network coverage area.

4. Carrier-Specific Blocks (T-Mobile Users)

If your carrier is T-Mobile, they may block short codes. In this case, please contact T-Mobile to remove any blocks on short codes or numbers, especially the long code number "18888927180," which is commonly affected.

5. Phone Settings

Some phones, particularly Android devices, have settings that can block messages from unknown numbers. Please check your phone’s settings or reach out to your carrier for assistance in adjusting these settings.

6. Payment or Credit Issues

Ensure that there are no payment issues preventing SMS delivery, such as insufficient credits with your mobile carrier to receive messages.

7. WiFI + Mobile Data

Try connecting to WiFi instead of using your cellular signal, mobile operator outages can impact the delivery of the OTP/SMS text.

8. Mobile Number Use

We recommend that you use real carrier/mobile operator and avoid virtual numbers as those can be filtered by our messaging system.

9. Alternative Option - Email Notifications

If you are still unable to receive SMS, you can temporarily remove the primary mobile number from your account and opt to receive notifications via email. If the issue persists after checking these points, you may try removing the current phone number from your Seller Central account and adding an alternative number that can receive SMS notifications.

Steps to Update Contact Information:

1. Log in to your Seller Central account.

2. Navigate to the Home page.

3. Click the widget icon in the top right corner of the Home page and select "Login Settings."

4. You will see your primary phone number and email address. Click "Edit" next to the phone number.

5. Follow the on-screen instructions to update your contact details.

6. Once the deposit method update is complete, you can re-add your original phone number.

Important Reminder: We recommend completing the action within 15 minutes after receiving the SMS to ensure a smooth process.

I hope this helps,

Connor
