The emergence of ChatGPT marks a new era in artificial intelligence. Whether for writing assistance, coding support, or daily Q&A, ChatGPT can become your powerful assistant.

Prerequisites Before ChatGPT Registration

Before starting registration, you need to prepare:

1. Stable internet connection: Ensure you can access the OpenAI website
2. Email address: Gmail or Outlook recommended
3. Virtual phone number: The hardest part—need a number that can receive international SMS

Why Do You Need a Virtual Phone Number?

OpenAI requires phone verification to confirm account authenticity and prevent abuse. Unfortunately, mainland China numbers aren't on the supported list, which is why we need OmniSMS's virtual number service.

OmniSMS provides these advantages:

• Support for numbers from US, UK, Canada and other countries
• Instant availability, simple operation
• Fast reception, high success rate
• Protects your real number privacy

Detailed Registration Steps

Step 1: Visit OpenAI Website

Open chat.openai.com and click "Sign Up".

Step 2: Enter Email Information

Register using your email. Gmail recommended for better compatibility.

Step 3: Create Password

After creating a password, OpenAI sends a verification link to your email.

Step 4: Verify Email

Log into your email and click the verification link.

Step 5: Enter Personal Information

Enter your name and date of birth.

Step 6: Phone Verification (Key Step)

This is where errors most commonly occur. After selecting the country code, enter the virtual number provided by OmniSMS and wait for the verification code.

Common Issues and Solutions

"Our systems have flagged unusual activity"

This is caused by OpenAI's risk control. Try:

• Change to a different virtual number
• Use US nodes instead of Hong Kong or Southeast Asia
• Wait a few hours and try again

Not Receiving Verification Code

• Check if the number has expired
• Confirm country code selection is correct
• Try a number from a different country
