Hi @Seller_KMWOrfGkHUmfD

Connor from Amazon here to help.

I understand that sometimes you encounter issues you've while updating your deposit method or you simply don't receive your OTP on Seller Central. Below are some steps that you can take to remedy the issue:

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. Number Issue

Make sure that the phone number the OTP is sent to isn't a virtual one. Virtual numbers can sometimes filter text messages by companies which can cause your issue.

If you have an alternative number, please try using it to see if you can receive text messages that way.

Let me know if you still experience issues,

Connor
