Claude Design Guide: Account Verification in the Fable 5 Era
Need quick verification codes? Start your verification journey now
June 10, 2026 update: Claude Fable 5 is live
Anthropic released Claude Fable 5 and Claude Mythos 5 on June 9, 2026. The official model page lists claude-fable-5 with a 1M context window, 128k max output, and API pricing of $10 per million input tokens and $50 per million output tokens.
Key facts
- Claude signup still requires a text-capable phone number from a supported location. The Help Center says VoIP, Google Voice, app-created numbers, landlines, and numbers that cannot receive texts are not accepted.
- Phone verification and Claude identity verification are separate layers: certain capabilities, integrity checks, or compliance triggers may require Persona identity verification with a physical government photo ID and live selfie.
- Claude Design launched on April 17, 2026 with Opus 4.7 as its vision foundation. After Fable 5, Claude account signup, phone verification, and identity verification still use the same account system.
Signup guidance
- SMS-Act only provides one-time temporary numbers valid for 15 minutes; it is not intended for long-term number holding, fixed numbers, or account trading.

What Is Claude Design? Core Features
Claude Design is Anthropic Labs' collaborative visual creation tool, built for founders, PMs, and non-designers who need to ship polished visuals fast.
Core capabilities:
- Natural language to visuals: Describe what you need and Claude produces an initial version. Refine through conversation or direct edits.
- Automatic Design System: During onboarding, Claude reads your codebase and design files to extract colors, typography, and components. Every subsequent project inherits this system automatically.
- Multi-format export: Export as PDF / shareable URL / PPTX, or send to Canva for further editing.
- Developer handoff: Package finished designs into a handoff bundle and pass directly to Claude Code with one instruction.
Claude Design vs Figma: Figma excels at real-time collaboration and precise vector control. Claude Design excels at "zero to draft" speed. Most industry observers position Claude Design as a tool for non-designers rather than a full Figma replacement.
How to Start Using Claude Design
Prerequisites and step-by-step access:
- Subscribe — Visit claude.ai and upgrade to Pro ($20/month) or Max. Team/Enterprise tiers are activated by workspace admins.
- Create account — New users need email + phone verification. Anthropic enforces regional restrictions; many regions cannot complete verification with local numbers.
- Pass phone verification — This is where most users get stuck. Use an SMS-Act international one-time number to receive the code in about 30 seconds.
- Open Claude Design — After login, select Claude Design from the product menu and complete Design System onboarding.
Note
Claude Design is currently a Research Preview. Advanced features such as multi-user real-time collaboration are rolling out gradually.

Frequently Asked Questions
Q1: Can free Claude users access Claude Design? No. Claude Design is limited to Pro, Max, Team, and Enterprise subscribers.
