How to Verify Kraken Without a Phone Number

A practical guide — 2026

Kraken is one of the longest-running and most trusted cryptocurrency exchanges, serving millions of users across more than 190 countries. Founded in 2011, Kraken offers spot trading, futures, staking, and OTC services for a wide range of cryptocurrencies. Because Kraken operates as a regulated financial platform — holding money transmitter licenses in the US and authorization in the EU and UK — it requires phone number verification during account creation as part of its identity and fraud prevention process.

When you register for Kraken, the platform sends a one-time SMS code to the phone number you enter. Kraken performs a carrier-type check before sending any code, and VoIP numbers are rejected at this step. To receive Kraken’s SMS verification without using your personal number, TextVerify.io provides real non-VoIP US carrier numbers with private inboxes. Enter the number when Kraken requests verification, receive the code privately, confirm it, and your account setup continues.

Short answer: Kraken rejects VoIP numbers before sending any SMS code. A real non-VoIP carrier number from TextVerify.io passes Kraken’s carrier check. Enter it during Kraken sign-up, retrieve the code from your private TextVerify inbox, confirm it, and verification is complete.

Why Kraken Requires Phone Verification

Kraken is regulated under US state money transmitter licenses and holds authorization from financial regulators in the EU and UK. Phone verification is embedded in its compliance framework for multiple reasons:

Account registration. Kraken sends a six-digit SMS code to the phone number entered during sign-up. The account cannot be used for trading, depositing, or withdrawing until this code is confirmed. This step is mandatory for all new accounts regardless of the user’s country or the verification tier they intend to reach.
Two-factor authentication (2FA). Kraken uses the registered phone number as the default 2FA channel. On each new device login, an SMS code is sent to the registered number to confirm your identity. Kraken also supports hardware security keys (YubiKey) and TOTP authenticator apps (Google Authenticator, Authy) as alternative 2FA methods — switching to one of these after registration removes the ongoing SMS dependency.
KYC verification tiers. Kraken’s account system has multiple tiers (Starter, Express, Intermediate, Pro) with increasing deposit, trading, and withdrawal limits. Phone verification is the baseline requirement. Higher tiers require government-issued ID, proof of residence, and in some cases a selfie or video verification. The phone step must be completed before any KYC documents can be submitted.
Withdrawal security confirmations.This prevents unauthorized asset withdrawals even if an attacker has your login credentials. A reachable number is important for these transaction-level security checks.

Kraken validates the carrier type of every submitted phone number before sending any SMS. VoIP numbers are identified and blocked instantly. TextVerify numbers are provisioned from real US carrier networks and pass this check.

What Does Not Work

These commonly tried options fail at Kraken’s phone verification step:

Google Voice. VoIP. Kraken’s carrier check identifies Google Voice and rejects it before any SMS is dispatched. This is one of the most frequently attempted workarounds for crypto exchange verification and it consistently fails on Kraken.
TextNow, Hushed, 2ndLine, Sideline. All VoIP. App-based numbers route through internet infrastructure rather than licensed carrier networks. As a regulated exchange holding crypto assets on behalf of users, Kraken applies strict number validation and blocks all VoIP numbers before sending any code.
Free public SMS receiving websites. Numbers from public SMS sites are blocklisted by Kraken. These sites also display all incoming messages publicly, making your Kraken verification code visible to anyone on the internet — a serious security risk for an account that will hold crypto assets.
A number already registered on another Kraken account. Kraken ties phone numbers to accounts for identity management. A number previously used to register a Kraken account cannot be used again to open a new one. Use a fresh TextVerify number for each new Kraken registration.
Skipping phone verification entirely. Kraken’s registration flow requires phone verification to be completed before any account functionality is accessible. There is no way to proceed to trading or depositing without confirming the SMS code.

TextVerify.io numbers originate from real US mobile carrier infrastructure. They pass Kraken’s carrier-type check, and the verification code arrives in a private inbox only your TextVerify account can access.

Step-by-Step Guide

Here is how to verify your Kraken account without using your personal phone number:

1

Get a US carrier number from TextVerify

Go to textverify.io, create a free account, and add credits. Search for Kraken in the platform list and select an available US number. The number is assigned instantly. Open your TextVerify inbox in a second browser tab and keep it ready before beginning Kraken registration.

2

Go to Kraken and begin registration

Visit kraken.com and click Create Account. Enter your email address, create a username, and set a strong password. Continue through the registration form until Kraken asks for your phone number to send an SMS verification code.

3

Enter the TextVerify number

Select United States (+1) from the country code dropdown. Paste your TextVerify number into the phone field and click Send Code. Kraken validates the carrier type — TextVerify numbers originate from real US carrier infrastructure, so the check passes and the SMS is dispatched immediately.

4

Get the code from TextVerify

Switch to your TextVerify tab. The Kraken six-digit verification code appears in your private inbox within seconds. Copy the code. Only your TextVerify account can access this inbox — the message is not visible to anyone else.

5

Confirm the code and switch 2FA to an authenticator

Enter the code in Kraken’s verification field and click Submit. Phone verification is complete and your Kraken account is created. Immediately go to Security → Two-Factor Authentication in your Kraken account settings and switch 2FA from SMS to an authenticator app (Google Authenticator or Authy) or a hardware key. This removes the ongoing SMS dependency for future logins.

⚠️ Switch to an authenticator app immediately after setup. Kraken explicitly recommends moving away from SMS-based 2FA because SMS is vulnerable to SIM-swap attacks. Switching to a TOTP authenticator app or hardware key right after account creation is both a security best practice and practically important — it means future Kraken logins no longer depend on the TextVerify number being active.

Common Mistakes to Avoid

  • Using a VoIP number. Kraken’s carrier validation rejects all VoIP numbers before sending any SMS. Google Voice, TextNow, Hushed, and every other app-based phone number fail at this step. A real US carrier number from TextVerify is required.
  • Not switching to an authenticator app after registration. SMS 2FA on Kraken means every new device login triggers an SMS to the registered number. If the TextVerify rental expires and you haven’t switched to an authenticator, future logins from new devices will be blocked. Switch 2FA immediately after creating the account.
  • Using a number already tied to another Kraken account. Kraken ties phone numbers to accounts. A number previously used for a Kraken registration cannot be reused. Always use a fresh TextVerify number for a new account.
  • Confusing phone verification with KYC tiers. Phone verification gets you a Starter-tier Kraken account with basic access. To increase trading and withdrawal limits, Kraken requires identity document verification (Express, Intermediate, or Pro tier). Phone verification and KYC document review are separate processes.
  • Entering the code after it expires. Kraken’s SMS codes expire quickly. Have your TextVerify inbox open before clicking “Send Code” in Kraken so you can paste the code the moment it arrives.
  • Forgetting to update the phone number before the rental expires. If you keep SMS as your 2FA method, update the Kraken account phone number to a new number before the TextVerify rental expires. To change the number, Kraken will send a code to the currently registered number, so the change must be made while the TextVerify number is still active.

Frequently Asked Questions

Q

What are Kraken’s account verification tiers?

Kraken has four verification tiers: Starter (email and phone verified — basic crypto deposits and withdrawals, limited fiat access), Express (ID verified — higher limits), Intermediate (full KYC with ID and proof of address — full fiat deposits and withdrawals), and Pro (highest limits, OTC trading access). Phone verification gets you to the Starter tier. Each subsequent tier requires additional identity documents submitted through Kraken’s verification portal.

Q

Why does Kraken recommend switching away from SMS 2FA?

Kraken, like most security-conscious exchanges, discourages SMS 2FA because of SIM-swap attacks — a type of fraud where an attacker convinces a mobile carrier to transfer your phone number to a SIM they control, giving them access to your SMS codes. A hardware security key (YubiKey) or TOTP authenticator app generates codes locally without any carrier involvement, making them immune to SIM-swap attacks. Kraken supports both as 2FA options.

Q

What cryptocurrencies does Kraken support?

Kraken supports over 200 cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Cardano (ADA), XRP, Polkadot (DOT), Chainlink (LINK), and many others. It also offers crypto staking for eligible assets, futures trading with leverage, and OTC trading for large orders. Kraken is particularly known for its deep liquidity, low fees, and strong security track record since its founding in 2011.

Q

Can I update my Kraken phone number after registration?

Yes. You can update the phone number in your Kraken account under Security → Phone. To confirm the change, Kraken will send a code to the currently registered number. Make this update while your TextVerify rental is still active. Alternatively, switch to an authenticator app for 2FA first — this removes the phone dependency entirely for login purposes, making phone number management less urgent.

Q

How does Kraken compare to Coinbase and Binance?

Kraken is generally preferred by intermediate to advanced traders for its lower fees, wider range of trading pairs, futures trading, and strong security reputation. Coinbase is more beginner-friendly with a simpler interface and broader US regulatory standing. Binance has the highest global trading volume and the widest coin selection but has faced more regulatory scrutiny in some markets. All three require phone verification that can be completed using a TextVerify non-VoIP carrier number.

✅

Bottom line

Kraken’s phone verification requires a real non-VoIP carrier number — VoIP numbers are rejected before any code is dispatched. TextVerify.io provides real US carrier numbers that pass Kraken’s check. Get the number, enter it during Kraken registration, retrieve the six-digit code from your private TextVerify inbox, and confirm it. Immediately after account creation, switch Kraken’s 2FA from SMS to an authenticator app or hardware key — this is both a security best practice and removes the ongoing SMS dependency. Higher KYC tiers and full trading limits require separate identity document verification.
