Registration & Account Creation FAQ
Many users run into email verification failures or phone number issues when registering for Claude. First, make sure your network connection is stable. Stick to mainstream email providers like Gmail or Outlook, as some local email services may experience delays. If you don't see the verification email, check your spam folder and try resending. When it comes to phone numbers, Claude supports numbers from certain countries. +86 numbers from China are sometimes restricted, so try switching networks or waiting a while before retrying.
Another common question is "This email is already registered." This usually happens if you previously used the same email for another Anthropic service, such as an older version of Claude. Try logging in directly or use the "Forgot password" option to reset. If that doesn't work, consider registering with a new email address.
Account Binding & Login Issues
When binding a third-party account (like Google or Apple ID), you may occasionally see an "association failed" message. This is often caused by browser cache or cookie conflicts. Clear your browser cache, sign out of all Google accounts, and try again—it usually works. If you want to unbind or switch the linked third-party account, go to Claude settings, disconnect the current binding first, then connect a new one.
Getting kicked out frequently after logging in or seeing a "session expired" prompt is another common issue. This could happen if you're logged in on multiple devices at once, or if your network IP keeps changing. It's best to use only one device and avoid unstable public Wi-Fi or VPN connections. If the issue persists, try clearing your session records in settings and logging back in.
Feature Usage Questions & Solutions
Many users report that Claude suddenly stops responding during a conversation or that the output gets cut off. This is usually due to exceeding the conversation context length limit. Claude Free has a conversation limit; once you hit it, start a new conversation. For Pro subscribers, check if you've reached the message cap—either wait or upgrade to the Team plan. If you see errors like "request error" or "network connection abnormal," first check your network status, then refresh the page or restart the app.
Regarding file uploads, some users find that Claude cannot parse uploaded PDFs or images. Claude natively supports text-based files like .txt and .md. For images, it relies on OCR, so low resolution or handwriting may cause recognition failures. For best results, upload high-resolution images with clear text, or paste the text directly into the chat. For large files, try compressing them and uploading in smaller parts.
