🇧🇷 Brazil (+55) Numbers for
OpenAI / ChatGPT OTP
Rent a private, Non-VoIP Brazil (+55) mobile number to receive your OpenAI / ChatGPT SMS verification code in seconds. Provisioned across Brazilian +55 (DDD 11, 21, 31, 41) mobile SIM pools via Vivo, Claro Brasil, and TIM at $0.35 USD per 10-minute session with 100% automatic refund protection.
How to Enter a Brazil (+55) Number in OpenAI / ChatGPT
Over 20% of failed international OTP deliveries happen because of duplicate country codes or unstripped domestic trunk prefixes. Follow the exact Brazil (+55) formatting rules below when verifying OpenAI / ChatGPT:
National Subscriber Digits Only
When you select 🇧🇷 Brazil (+55) from OpenAI / ChatGPT's country dropdown, paste only the subscriber digits above without repeating +55.
ITU-T E.164 Full String
If OpenAI / ChatGPT or your API testing script asks for a single international E.164 phone string (Display format: +55 11 91234-5678), include the leading +55 prefix.
Domestic Trunk Prefix Policy
Enter the 2-digit DDD state area code + 9-digit mobile number directly after +55 (strip any domestic long-distance carrier prefix like 015 or 021).
OpenAI / ChatGPT Pro Tip: Ensure you select "Send code via SMS" (not WhatsApp) during the OpenAI verification prompt, and use a supported country code that matches your current connection region.
