SMS Verification for OpenAI, ChatGPT & AI Tools (2026)

By The CODASMS TeamUpdated June 30, 2026

Quick answer: AI platforms like OpenAI/ChatGPT require phone verification at signup. With CODASMS, choose the service, pick a country (US/UK clear AI tools most reliably), and the code lands in your dashboard in seconds. Because AI signups can be region-sensitive and demand is high, a quality number and pay-per-code refunds make it painless.

Why AI tools ask for a phone number

OpenAI and similar platforms use phone verification to limit abuse and one-account-per-person rules. That means a real number that can receive an SMS — but not necessarily your personal one. A dedicated number keeps your main line out of yet another platform's records while still passing verification.

How to verify an AI tool step by step

Choose the service. Select OpenAI/ChatGPT (or the AI tool you need) in CODASMS.
Pick a reliable country. US (+1) and UK (+44) numbers clear AI platforms most consistently.
Enter during signup. Add the number when the platform requests phone verification.
Receive the code. It appears in your dashboard, usually within a minute.
Retry free if flagged. Cancel for an automatic refund and try another number if needed.

Region note. Some AI tools are region-restricted. If a platform isn't available in a country, a number from a supported country is part of how people access standard signup — always within the platform's own terms.

Speed matters for AI signups

AI platforms sometimes time out the verification screen quickly. A Priority number is worth it here — it pulls from faster-clearing pools so the code arrives before the window closes.

Pay only when it works

High-demand services see more flagged numbers. With pay-per-code, any number that doesn't deliver is refunded automatically, so you can retry until one clears without paying for the misses.
