Barclays has not published a verified definition or a code-specific fix for error 00002 in the information available here. User reports describe it appearing during app access, but they do not establish whether the cause is an outage, a security check, or an account issue. Start with low-risk checks; if the problem involves registration or account verification, contact Barclays through a verified channel.
What does Barclays error code 00002 mean?
Its official meaning is unconfirmed. A MoneySavingExpert forum discussion includes reports of the code appearing while people tried to access the app, but those are individual experiences rather than a Barclays diagnosis. One contributor said the app asked them to try again and mentioned an in-app Direct Call option that was not visible on their screen. Read the user reports on MoneySavingExpert.
An unofficial error-message listing associates the code with the wording “We’re sorry something’s gone wrong. Please try again.” That listing is not an official Barclays source, so treat the wording as an example rather than a guaranteed message. See the third-party error listing.
There is not enough evidence to say that 00002 always means Barclays is down, that the bank has blocked access for security reasons, or that a particular account detail is wrong.

What to try if you cannot log in
- Check that you are using Barclays’ genuine app or website. Open the app you normally use, or type Barclays’ known official web address yourself rather than following an unexpected link.
- Close and reopen the app. Then follow any instructions currently shown by Barclays. This is a basic check, not a code-specific remedy confirmed by the bank.
- If the message continues, use a verified Barclays support channel. Find contact details or support options in the genuine app or on Barclays’ official site. Explain when the code appears and what you were doing immediately beforehand. The current Barclays workflow specifically for error 00002 could not be verified, so follow the bank’s live instructions rather than relying on an old or unofficial procedure.
When the issue may involve registration or account details
People in the forum discussion described different circumstances, including seeing the error shortly after opening an account and having trouble associated with a mobile number or profile. One contributor said a branch visit was needed after an older mobile number was connected to earlier account details. These are anecdotes, not confirmed causes of error 00002; they cannot identify what is wrong with another customer’s account.
If you are setting up the app, changing a phone number, or being asked to verify your identity, contact Barclays through a verified channel. Do not share your card PIN, passcode, security code, or one-time code with anyone who contacts you.

Should you reinstall the Barclays app?
Reinstalling is not a guaranteed fix and may require you to register again. In one forum report, a user could not continue because they had not yet received the card PIN requested during re-registration. Before removing the app, make sure you have access to the information Barclays may ask for and can complete its current verification process. If you are unsure, ask Barclays before reinstalling.
