Quick answer: Fiverr asks for a phone number to sign up or secure your account. When your local number fails or is rejected, rent an overseas real-SIM number on SimSmsBox and complete the SMS step. Note becoming a seller may need ID verification — receive-SMS only covers the phone step.

Note: Receive-SMS completes phone / account-security verification. To become a seller or withdraw earnings, Fiverr may require ID verification and payout details — handled by you, not a platform.
Here’s the receive-SMS path to get Fiverr phone verification done.
Why it fails
- Virtual / VOIP numbers flagged by Fiverr’s risk control;
- Free-pool numbers reused and pre-flagged;
- Number country mismatched with login IP;
- One number reused for many accounts.
Troubleshoot: SMS code not received.

New to the flow? How to use an SMS platform.
1. Reach the phone step first
Finish email / profile fields before buying a number so you don’t waste the rental window.
2. Pick country + real SIM
Keep the country close to your network; prefer physical — see real SIM vs virtual.
3. Purchase
Use service fiverr (check the shop list):
curl -X POST https://api.simsmsbox.com/api/sms/orders/purchase \
-H "X-API-Key: psk_xxx" -H "Content-Type: application/json" \
-d '{"service":"fiverr","country":"US","cardKind":"physical","rentDays":30}'
4. Request SMS (not a call)
Enter the number and send via SMS, not voice.
5. Poll the code
curl https://api.simsmsbox.com/api/sms/orders/91 -H "X-API-Key: psk_xxx"
# -> { "status": "received", "latestCode": "482913" }

FAQ
Q: Fiverr keeps saying the number is invalid? Try another real SIM / country; free-pool numbers almost never pass.
Q: Can receive-SMS pass seller identity checks? No — seller verification needs your ID; receive-SMS only handles phone verification.
Q: Will it get banned? Real SIM + normal use is lower risk; don’t mass-create accounts on rented numbers.
Takeaway
Stuck on Fiverr phone verification? Use a clean overseas real-SIM SMS number — nearby country, SMS only, poll the code. Platform comparison: SMS platform vs 5sim.
