What is error code U13 in Google Pay?
The U13 code in Google Pay is an error message that appears when the app can't establish a secure connection with your bank's servers .

The error can occur on both Android and iPhone devices and is not always the user's fault, as in many cases it originates from server-side problems , either on the part of Google or the bank in question.
Common causes of error U13
There are multiple reasons why this message may appear. Below we detail the main causes detected:
- Server saturationBanks, especially smaller ones, have limited capacity to handle multiple requests simultaneously. If the server is overloaded, Google Pay won't be able to connect properly.
- Bank maintenance: Your bank's infrastructure may be undergoing maintenance or experiencing technical issues, making it impossible to validate the data you're trying to query or add. In similar situations, it's helpful to know how to solve errors related to software failures.
- Unstable network connectionA poor Wi-Fi or mobile data signal can make it difficult for the app to access servers securely. Connection quality is critical for these types of transactions.
- Outdated version of the appIf you're using an older version of Google Pay, it may not be fully compatible with your bank's current systems or the app itself.
- Incorrect information about your bank accountIf you entered any bank details incorrectly when setting up or updating your account, Google Pay may not be able to connect to the correct server and you will see the U13 error.
When this error appears
The error is not limited to a specific action , but can appear at different times. The most common are:
- When trying add a new bank account
- When you start a transaction or payment
- When consulting the available balance
In all of these situations, if the system cannot properly verify the connection with your bank, the code U13 will be displayed.
Steps to fix Google Pay error U13
Now that you know the most common causes, here's what you can do to resolve the issue and get back to using Google Pay normally:
1. Wait and try again
It might seem like a simple solution, but in most cases, the error is due to temporary server congestion . Wait a few minutes, or if possible, a few hours, and try again. We recommend trying during off-peak hours, such as early morning or evening, when fewer users are online.
2. Check your Internet connection
Make sure you're using a stable connection, either Wi-Fi or mobile data . If you're in an area with poor coverage, switch networks if possible. A poor connection can prevent the app from communicating properly with the bank's servers, causing these types of errors.

3. Update the application
Check your app store (Google Play or App Store) for available updates for Google Pay . Always install the latest version, as it usually includes stability improvements, bug fixes, and compatibility with newer operating systems. If you're already experiencing errors on your device, you can find instructions on how to troubleshoot errors in Windows.
Older versions may contain errors or be unsuitable for recent security updates implemented by banks.
4. Clear Google Pay data and cache
In some cases, the data stored by the app may be corrupted or outdated. Cleaning it up can help:
- Open the app Configuration on your device.
- Go to the section Applications o Apps.
- Search Google Pay on the list.
- Press on Storage.
- Choose Clear cache & AFTER Delete data o Storage.
Once this is done, open Google Pay again and sign in to see if the error has been resolved.
5. Review the bank details entered
It's crucial that the information you entered (such as account number, bank name, and other details ) is correct. If there are errors in the information, Google Pay won't be able to connect to the correct server, and error U13 will appear. If you have any doubts, it's recommended to check for errors in other associated apps, as mentioned in this article about common errors when buying smartphones.
If in doubt, carefully remove the bank account from the app and add it again.
6. Try using other payment methods
If you need to make an urgent transaction, consider using temporary alternatives like Paytm, Venmo, or even withdrawing cash from a Google Pay-compatible ATM. This will give you some breathing room while the problem is being resolved.
Errors related to payment method verification
Sometimes, the U13 error can also be linked to problems with payment method verification , especially if Google has asked you to validate a card or account.
What to do if the verification code is not sent?
- Make sure you have funds in the linked account.
- Please check that the information you entered, such as name, address, and security code (CVC), is correct.
- If the system allows it, try to perform the verification. uploading identity documents.
- As a last resort, use another payment method.
Can't find the code?
Google may place a temporary charge of $1,95 on your card. This charge is usually accompanied by a numerical identifier, which is the verification code . If it doesn't appear:
- Wait a few days, as it sometimes takes time to reflect.
- Check your bank account statement or history.
If you don't have the code after 7 days, try verifying with documents or changing your card.
The code does not work or has expired
Make sure you're using the correct code and that it was requested recently. If it's been a long time (more than 14 days), it has probably expired and you'll need to request a new one.
What if the code cannot be entered?
This can happen if you removed the card before entering the code. In that case:
- Please add the card again.
- Request another code.
- Please verify with documents if possible.
Another important point is that if a temporary charge was generated for verification but you did not accept it, the refund may take up to 30 days to be completed.
