Real carrier-issued SIM cards. OpenAI blocks VoIP numbers — Google Voice, TextNow, and Twilio all fail. Pay only when ChatGPT's code lands in your inbox.
TL;DR
None of these are sketchy. They're the reasons we hear from customers every day.
OpenAI limits one account per phone number. Virtual numbers let you create separate ChatGPT accounts for different projects or teams without linking personal data.
Your real mobile number can reveal your identity and location. A virtual number keeps your personal number out of OpenAI's database entirely.
ChatGPT is unavailable in some countries. A virtual number from an eligible country lets you register regardless of where you actually are.
Tying your ChatGPT account to a personal number creates SIM-swap vulnerability. Virtual numbers carry zero risk — discard after use.
Developers building on the OpenAI API often need clean accounts for testing. Virtual numbers make spinning up fresh environments fast and cheap.
Different tools for different jobs. OpenAI is stricter than most services — picking the right tier matters.
You're testing the signup flow once and the account is fully disposable
You need ChatGPT verified once and you won't need to re-verify later
You need to access the ChatGPT account repeatedly — password resets, device switches, API key rotation
Our honest recommendation
If this is a one-shot ChatGPT signup, pay-per-verification is almost always the right choice. Free shared inboxes fail more often than they work on ChatGPT — OpenAI aggressively blocks reused numbers. If you need the account long-term (business use, repeated API logins), go rental.
Full flow, end to end.
Email only — no phone number to register. Free account, no credit card to see pricing.
Minimum $2. Pay with BTC, USDT, ETH, LTC via NOWPayments, or credit/debit card. Unused balance doesn't expire.
Select ChatGPT from the services list. Choose a country (US and UK have the highest acceptance rates). Click 'Buy number' — you get a real SIM number instantly.
Go to chat.openai.com → Sign up → enter the number exactly as shown (country code + number). ChatGPT sends the SMS within 30 seconds.
The 6-digit code appears in your dashboard the moment ChatGPT sends it. Copy it into ChatGPT. If nothing arrives in 2 minutes, hit Cancel for a full refund and grab a different country.
Your ChatGPT account is verified and ready. For ChatGPT Plus, add payment after signup. For API access, go to platform.openai.com and create an API key.
All prices include instant delivery. Real physical SIM numbers from carrier networks. Starting from $0.09 per SMS.

Success rates shown reflect ChatGPT verification performance on VirtualSMS. US and UK numbers outperform budget tiers by a significant margin on AI services. Live availability and pricing update on the page below.
These are the actual failure modes we see. Each has a specific fix — don't just retry blindly.
OpenAI has blocklisted this specific number range or carrier prefix — usually happens with budget-tier numbers that have been heavily reused across the industry.
Cancel the current number on VirtualSMS (get a full refund). Switch to a Tier 1 country (US, UK, DE, CA). OpenAI's blocklist is carrier-range based — a fresh number from a different carrier in a different country bypasses it.
OpenAI tracks verified numbers globally. This number was used by a previous buyer for the same purpose.
VirtualSMS tracks number history to avoid reassigning flagged numbers for the same service, but cross-platform reuse can still trigger this. Request a fresh number — OpenAI's error is exact, not ambiguous.
The code expired (valid for about 10 minutes), or a newer code was sent and overwrote the one you typed.
Always use the MOST RECENT code in your VirtualSMS inbox. If you hit resend on ChatGPT, earlier codes are invalidated — use only the latest.
Either this specific SIM is rate-limited by OpenAI, or the SMS route from OpenAI's gateway to this carrier is congested.
Hit Cancel for a full refund. Try a different country. US, UK, and Germany currently have the best ChatGPT SMS delivery speed in our fleet.
OpenAI's post-signup fraud detection flagged unusual behavior — not the number type itself.
New OpenAI accounts need gradual warmup: use ChatGPT normally for a few days before switching to API or high-volume use. Don't query 100 prompts on day one. This is an OpenAI behavior rule, not a virtual-number rule.
Real carrier SIM cards from licensed mobile networks. Not VoIP. Not virtual. Real numbers that apps trust.
SMS codes arrive within seconds. No waiting, no refreshing, no anxiety.
From UK to Indonesia, we have real SIM numbers from over 50 countries.
No subscription, no commitment. Pay only when you receive an SMS.
No logs, no tracking. Your personal number stays completely private.
Our real SIM infrastructure delivers 95%+ verification success. Full refund if it fails.
Yes. ChatGPT's phone verification accepts virtual numbers from most countries. US and UK numbers have the highest success rates. Simply enter the virtual number during signup and enter the SMS code you receive on your VirtualSMS dashboard.
Most codes arrive within 10–30 seconds of requesting them on ChatGPT. In rare cases delivery takes up to 2 minutes. If no code arrives after 2 minutes, request a new number and try again — VirtualSMS refunds automatically.
No. Once your ChatGPT account is verified, you never need to enter a phone number again. The virtual number can be discarded — your account stays active permanently.
No. OpenAI links each phone number to one account. To create multiple accounts, purchase a separate virtual number for each one.
OpenAI is a US company and its fraud-detection systems are tuned for US carrier patterns. US virtual numbers that run on real carrier SIMs (like VirtualSMS uses) closely mimic real US mobile numbers, resulting in the highest verification acceptance rates.
This means the specific number's carrier range is on OpenAI's blocklist. Release the number and get a fresh one — ideally from a Tier 1 country (US, UK, Germany, Canada). VirtualSMS only charges for numbers that successfully deliver an SMS.
OpenAI's ToS restricts creating accounts for the purpose of circumventing limitations. Using a virtual number for legitimate privacy or multi-account use is a gray area. We provide the technical service; you are responsible for complying with OpenAI's terms.
Yes. Both ChatGPT Plus accounts and OpenAI API accounts require the same phone verification step. A virtual number works identically for both.
Same real-SIM infrastructure. Swap the service, keep the reliability.

Why ChatGPT / OpenAI Rejects Your Phone Number — And the Real Fix (2026)
OpenAI rejects your phone for 4 specific reasons: VoIP detection, country restriction, recycled-number flag, carrier reputation. Here's the diagnosis tree + the real-SIM fix that works in 2026.
Princeton's Recycled Number Study — Why 66% of New Phone Numbers Still Have Old Accounts (2026)
Princeton CITP researchers Kevin Lee and Arvind Narayanan found 66% of recycled US mobile numbers were still tied to existing accounts at Amazon, Google, PayPal, Yahoo, AOL, and Facebook. Five years later the FCC 45-day rule still produces the same failure mode. The structural fix: per-activation real-SIM.
VirtualSMS operates its own physical SIM infrastructure for SMS verification. Every tier ranking and country recommendation on this page comes from our live order logs — not aggregator estimates, not scraped benchmarks. When OpenAI's behavior shifts, the rankings here shift with it.
Real physical SIM. 150+ countries. 90%+ first-try success. Refund if code doesn't arrive.
