Important Warning: Please request a phone number only when you have navigated to the active phone verification prompt on OpenAI Codex, preventing your session from timing out (verification codes typically expire within 5 to 15 minutes). You must strictly adhere to OpenAI's Terms of Service: never use verified accounts for automated spam bot networks, distributed denial-of-service (DDoS) operations, or malware deployment. If purchasing a one-time OTP tier, please note that major OpenAI platform security updates may periodically trigger re-verification prompts if you abruptly switch devices or IP locations.
CODEX OTP - Account Verification is a specialized verification service utilizing carrier-issued, non-VoIP mobile numbers from premier global telecommunication providers to bypass phone verification checkpoints when launching or authenticating OpenAI Codex. The service eliminates "Phone number required" and "Unable to send verification code" errors, enabling you to successfully unlock and activate your Codex environment within 1 to 3 minutes.
OpenAI enforces mandatory SMS phone verification to curb automated bot farm creation and manage computing resource allocations across high-tier code generation models. Following recent security framework releases, when users attempt to authenticate via the Codex Desktop app, execute tasks in the Codex CLI, or generate an initial API key on platform.openai.com, access remains restricted until a legitimate mobile number is validated via SMS OTP.
The "Phone number required" prompt signals an unverified account profile, whereas "Unable to send a verification code to this phone number" occurs when your personal phone number has exceeded its linkage allowance (typically capped at 2–3 accounts per number) or when local carrier networks fail to deliver international SMS traffic from OpenAI's gateways. CODEX OTP from Empire X delivers 100% clean, fresh phone numbers from supported tier-one countries (US, UK, EU, Vietnam), ensuring immediate SMS receipt without carrier rejection.
Yes, 100% of phone numbers provisioned by Empire X are genuine mobile lines (Carrier-issued SIMs) supplied by physical network operators (such as T-Mobile, AT&T, Vodafone, O2, Viettel), completely avoiding virtual VoIP (Voice over IP) or disposable eSIM ranges. As a result, Empire X numbers pass OpenAI's Carrier-lookup API checks with a 99.9% verification success rate.
Each phone number delivered by Empire X is dedicated strictly to a single OpenAI Codex account per order. This guarantees your verification is completely free from the "This phone number is already associated with the maximum number of accounts" rejection commonly encountered on public shared SMS pools.
Processing Time: 15–30 minutes during standard operating hours (actual OTP retrieval takes only 1–3 minutes).

Warranty Policy for Issues:
Disclaimer:
- Customers permitting the OTP session window to expire (exceeding 15 minutes post-number assignment) without triggering the "Send Code" action on the OpenAI platform.
- Accounts suspended or penalized by OpenAI after successful phone verification due to user violations of OpenAI Terms of Service (running scraper bots, exploit attacks, or distributing malicious content).
- Customers selecting a one-time OTP tier who subsequently encounter re-verification prompts after switching proxy IPs or logging in across unfamiliar networks without purchasing a Re-verify coverage plan.
- Customers selecting the wrong service category or entering the phone number under incompatible platforms, disrupting the inbound SMS routing pipeline.
CODEX OTP is a specialized verification service that provides real, carrier-issued mobile phone numbers to receive SMS verification codes for OpenAI Codex, Codex CLI, and OpenAI API developer accounts, permanently resolving mandatory phone verification blocks.
Free and cheap online SMS platforms use recycled, virtual VoIP numbers that are heavily blacklisted by OpenAI's anti-fraud systems; Empire X provides 100% clean physical carrier numbers that ensure fast delivery and account safety.
No, you never need to share your password or login details. You receive the phone number from Empire X, input it into your own Codex interface, and enter the returned 6-digit OTP independently.
The 6-digit verification code is retrieved and displayed on your screen within 10 to 30 seconds after you initiate the SMS request on OpenAI.
If an OTP code is not received within 5 to 10 minutes due to unexpected carrier routing delays, Empire X immediately assigns a replacement phone number or issues a 100% full refund.
No, each phone number is provisioned exclusively for one OpenAI Codex account to prevent account cross-contamination and avoid OpenAI's account limit warnings.
Yes, the numbers provided are fully compatible across the entire OpenAI ecosystem, including Codex CLI, the ChatGPT Desktop App, web logins, and initial API key generation on platform.openai.com.
If you anticipate future security re-verifications from device or network switches, we recommend selecting our CODEX OTP Re-verify package (retaining access for 30–60 days), allowing our team to capture additional OTPs on the identical number.
Empire X is Vietnam's premier digital services provider, offering genuine carrier-grade OTP verification with a 99.9% success rate, instant delivery, and dedicated customer support.
This error signifies that your previous number or country selection was flagged by OpenAI; simply contact Empire X support to receive an alternate tier-one number (such as US or UK), select the corresponding country code on OpenAI, and request the code again without issue.
