To fix Amazon verification codes not arriving on your phone, check the destination number and cellular reception, select Resend OTP, then check your messaging app’s filtered or blocked conversations. If the text still does not arrive, try an alternate verification method offered on Amazon’s sign-in screen.
The available choices depend on your account and the type of verification Amazon requests. Sign in only through Amazon’s own app or website, and never share a code, password, or remote access with someone who contacts you.
The short version
- Start with the destination: Check the phone associated with the number Amazon displays before requesting another code.
- Look inside your messages: A verification text may be in a filtered or blocked conversation without a normal notification.
- Try an enrolled alternative: Use a registered backup number or authenticator, or choose voice or WhatsApp delivery when Amazon offers it.
- Recover access when necessary: Try an existing trusted device before starting Amazon’s Two-Step Verification account recovery.
| Fix | When to use it | Main limitation |
|---|---|---|
| Check the number and resend | The expected text is missing | You need access to the destination phone |
| Try another verification method | SMS remains unavailable | Choose a method offered for your account |
| Check message filters and alerts | The code may have arrived silently | Menus depend on your phone and messaging app |
| Check your SMS app and cellular settings | Other SMS messages also fail | Account restrictions need provider assistance |
| Review call screening | An automated voice code is missing | Applies to voice verification only |
| Use a trusted device and correct your number | You already have a trusted device | Successful access is not guaranteed |
| Start account recovery | Your registered methods are inaccessible | Identity verification is required |
| Enroll an authenticator | You can access account settings again | Complete enrollment before using its codes |
Check the destination and request another code
Look at the destination number displayed on Amazon’s verification screen and check the phone associated with it. Confirm that the phone has cellular reception, then select Resend OTP when your sign-in screen offers that option.
If Amazon is sending the code to an old number, check whether you can still access your account. If you can, open Login & security and confirm the registered number, then correct the enrolled verification number using the steps below. If you cannot sign in, try an offered alternate verification method or account recovery.
Try another verification method
On an Amazon Two-Step Verification screen that offers it, select Didn't receive the OTP? and choose an available alternate method or registered number. The choices can include a backup number, voice call, or an enrolled authenticator. Choose a method you can currently access.
When the verification page offers WhatsApp delivery, select Send OTP by WhatsApp. Read the code in the WhatsApp account linked to your Amazon-registered phone number. That option depends on the verification flow, so choose another offered method when WhatsApp is not listed.
An authenticator can provide an Amazon code only after you enroll it with your account. Installing an authenticator while locked out does not complete that enrollment. If none of your registered methods is accessible, try an existing trusted device or start account recovery.
Look for filtered or blocked texts
On an iPhone using iOS 26, open Messages > Filters > Unknown Senders and look for the Amazon conversation. Open a recognized legitimate conversation and tap Mark as Known.
On iOS 26 and later where spam filtering is available, open Messages > Filter > Spam and select the message. Tap Not Spam, then tap Move to Inbox. If you have text filtering extensions enabled, open Messages > Filters > Manage Filtering > Text Message Filter and review their message categories too.
In Google Messages on Android, tap your profile photo or icon, then open More options > Spam & blocked. Select the legitimate sender and tap Unblock. Google says some of these steps require Android 7.0 or later.
When the code is present but you received no alert, check notification settings. In Google Messages, open the profile menu, select Messages settings > Notifications, and turn on Incoming messages. On Galaxy phones, also open Settings > Notifications and turn off Do not disturb if it is suppressing alerts.
On iOS 26, open Settings > Apps > Messages. Under Unknown Senders, open Allow Notifications and enable Time Sensitive; notification categories vary by country. These settings help you notice delivered messages, but they do not repair carrier delivery.
Check your SMS app and cellular connection
If other texts are missing too, check your phone’s SMS setup and cellular connection. On Android, open Settings > Apps > Default apps > SMS app and select your intended messaging app. Samsung labels the intermediate menu Choose default apps.
Samsung says Samsung Messages is no longer supported on U.S. Galaxy devices running Android 12 or later. On an affected phone, select Google Messages under Settings > Apps > Choose default apps > SMS app, or select Open Google Messages in the migration notice. Samsung’s discontinuation excludes Android 11 and earlier.
If you need to install it, get Google Messages through its official product page. For an existing installation, use the official store listing to update it. On Android phones using Google Messages, also check reception and turn off Airplane mode.
For an iPhone that has lost cellular service, open Settings, turn on Airplane Mode for at least 15 seconds, then turn it off. On a dual-SIM iPhone, open Settings > Cellular and select the line associated with Amazon’s number. If that line is disabled, tap Turn On This Line; contact your carrier if the line is missing.
After an iPhone SIM or carrier change, connect to Wi-Fi and open Settings > General > About. Install a carrier-settings update if offered. If phone-side checks do not restore verification texts, contact your mobile provider and ask it to check restrictions preventing incoming codes.
Check call screening if a voice code is missing
If you requested a voice code, check whether your phone is screening the automated call. On an iPhone with the current call-screening interface, open Settings > Apps > Phone. Under Screen Unknown Callers, select Never, then request the voice code again.
You can also check filtered calls in the iPhone Phone app. Open the Filter button, then select Unknown Callers or Spam and look for the verification call or voicemail. The filter sits in Recents in Classic view or Calls in Unified view, and a recorded code may already have expired.
On a Galaxy phone using Samsung Phone, open Phone > More options > Settings > Block numbers. Check whether the relevant automated caller is blocked and tap the red minus icon beside that number to unblock it. These changes affect calls, so return to the message and cellular checks if you requested a text code.
Try an existing trusted device
Before starting recovery, attempt to sign in from a device Amazon already trusts. This may let you access your account, although success is not guaranteed. If sign-in succeeds, open Your Account > Login & security to repair the verification settings.
To correct an enrolled verification number, select Manage or Edit beside Two-Step Verification (2SV) Settings, then open Enrolled 2SV Authenticators. Select Change for the number that needs correcting, or select Add new phone or Authenticator App to add a backup. Amazon supports up to two enrolled phone numbers.
Recover your account when registered methods fail
When your registered verification methods are inaccessible, open Amazon’s account recovery and select Sign in with Amazon. Enter your account email address or phone number and complete the authentication step. At the Two-Step Verification prompt, select Didn’t Receive the Code.
Choose Two-Step Verification Account Recovery and follow the identity-verification instructions. Amazon requires identity verification before changing your Two-Step Verification settings through this process.
Add an authenticator after signing in
Once you can access your account, enroll an authenticator for codes that do not depend on SMS delivery. Open Login & security and select Edit or Manage beside Two-Step Verification (2SV) Settings. Select Add new phone or Authenticator App, choose Authenticator App, and complete enrollment.
Microsoft Authenticator is one example Amazon names for compatible iOS and Android devices. To get it, open the Microsoft Authenticator product page and select Download the app. Finish enrolling it with Amazon before relying on its codes for future sign-ins.
Frequently Asked Questions
Can Amazon send the sign-in code to email instead?
For an eligible passwordless account, enter your registered email address on Amazon’s sign-in page and retrieve the code from email if that flow sends it there. This option applies to eligible passwordless sign-ins; follow any additional Two-Step Verification prompt using the choices it offers.
Can a passkey help me sign in without waiting for a text?
Use an already configured passkey when Amazon offers it, then authenticate with your device. To configure one while signed in, open Your Account > Login & security, select Set up beside Passkeys, then select Set up again. Amazon lists minimums of iOS 16, Android 9, macOS Big Sur, or Windows 10, with a supported browser and device; setup may be required separately for different marketplaces. If Amazon also presents a Two-Step Verification challenge, follow the choices on that screen.
Why is the code missing from T-Mobile DIGITS?
For T-Mobile short-code messages, check the handset containing your primary SIM instead of relying on a DIGITS app, web client, or paired line. T-Mobile says most short-code messages reach only the primary SIM. Its short codes are unavailable while overseas, so use an available Amazon alternate verification method when abroad.
What if my Amazon device has no separate verification code screen?
On device sign-in interfaces that cannot display a separate Two-Step Verification prompt, enter your email and password and select Submit. After the error, obtain a code through a working verification method, append it to your password, and submit again. This compatibility method still requires a working verification method and does not restore missing SMS delivery.
Why are international verification texts hidden in Google Messages?
On devices with a Singapore SIM and international-message filtering enabled, Google Messages can hide unknown international conversations. Open the profile menu > Spam & Blocked, select the conversation, and tap Move to inbox. Future messages in that conversation will reach the inbox.
