🐙Kraken Phone Verification: Register with SMS (Plus a Funds-Safety Note)

Kraken is a crypto exchange, so signup runs through phone verification and identity checks (KYC), and it strongly encourages 2FA. You can receive the verification code with a real-SIM number to explore the flow — but for an account that will hold funds, use your own long-term number and prefer an authenticator app for 2FA.

Why exchanges verify your phone and run KYC

• Compliance & identity: exchanges must run identity verification (KYC) by law.
• Account & funds security: phone verification plus 2FA protect your assets.
• Virtual numbers get rejected: prefer a real SIM, see Real SIM vs virtual numbers.

Verify Kraken with SimSmsBox

Step 1: Order a number

curl -X POST https://api.simsmsbox.com/api/sms/orders/purchase -H "X-API-Key: psk_xxx" -H "Content-Type: application/json" -d '{"service":"kraken","country":"US","cardKind":"physical","rentDays":30}'
# -> { "orderId": 63, "phone": "+1xxxxxxxxxx", ... }

Step 2: Enter the number and request the code

Step 3: Poll to retrieve the code

curl https://api.simsmsbox.com/api/sms/orders/63 -H "X-API-Key: psk_xxx"
# -> { "status": "received", "latestCode": "710845" }

Important: the safety boundary for funds accounts

This account will hold real money, so put security first:

• Use your own long-term number for the account you fund. A recycled receive-code number can create recovery risk later.
• Prefer an authenticator app (TOTP) over SMS for 2FA — it resists hijacking far better; see Security key vs SMS 2FA.
• Stay compliant with local law and the platform’s terms.

Wrap-up

Kraken’s phone verification receives fine on a real SIM, but keep funds accounts on your own long-term number with an authenticator app. Further reading: How to choose an SMS platform.
