Claude, Claude Code (CC) & Claude Design: Phone Verification with a Temporary Number

Claude (claude.ai), Claude Code (often shortened to CC) and Claude Design at claude.ai/design all sign in with the same Claude account. There is no separate phone check per tool — the SMS verification happens once, when you create the Claude.ai account. This guide shows how to pass it with a temporary number from jiema.my, then use every Claude product with that account.

One Claude account for Claude, Claude Code (CC) & Claude Design

Whether you chat at claude.ai, run Claude Code (CC) in your terminal, or build UIs with Claude Design (claude.ai/design), they all authenticate against your Claude.ai account. You verify a phone number only once — at signup — and every tool inherits it.

Why Claude requires phone verification

Anthropic uses a one-time SMS code at Claude.ai signup to confirm a real person and prevent automated abuse. Like other major AI platforms, Claude filters VoIP and recycled numbers, so some countries' pools verify reliably while others get rejected — picking a fresh, deep pool matters.

Country picks

Choose countries whose number pools are deep and recently active. On jiema.my the live stock count is the best signal — a large pool usually means recent activations are succeeding. These regions tend to work:

• Southeast Asia: Indonesia, Philippines, Vietnam
• Eastern Europe: Poland, Romania, Ukraine
• Latin America: Brazil, Mexico

If a number is rejected, cancel within the window for a full refund and try another country.

Step-by-step: verify your Claude.ai account

1. Start the Claude.ai signup with your email or Google login, until it asks for a phone number.
2. On jiema.my, browse to the Claude service, pick a country and place the order. The temporary number appears on your order page instantly.
3. Enter that number into Claude's phone field and request the SMS code.
4. The code arrives on your jiema.my order page within seconds — copy it and enter it on Claude.ai.
5. Your Claude account is now verified. The temporary number is no longer needed.

Using Claude Code (CC) & Claude Design after verification

Once your Claude.ai account is verified, sign in to Claude Code (CC) in your terminal, or open Claude Design at claude.ai/design, with that same account — no second SMS is required. The phone step is a one-time account gate, not a per-tool check.

Frequently asked questions

Do Claude Code (CC) or Claude Design need their own phone verification?

No. They authenticate with your Claude.ai account. Verify the account once with a temporary number, then log in to Claude Code or Claude Design normally.

Why was my number rejected by Claude?

Claude filters VoIP and reused numbers. Cancel the order within the 15-minute window for an automatic refund, then try a different country with a larger live stock count.

How long is the number active?

An SMS order on jiema.my stays active for 15 minutes. No code in that window means an automatic refund — so a rejected attempt costs you nothing.
