Verify Mercari with a Real US Number — Not VoIP
Mercari detects and blocks VoIP numbers instantly, showing "Please enter a valid mobile number." A dedicated US Real-SIM number is the only reliable fix — get yours and keep it active for re-verification and account security.
- Real-SIM numbers that pass Mercari's explicit non-VoIP check
- No "number already taken" — your number is dedicated exclusively to you
- Long-term rental — keep the same number for 2FA and account recovery
- Shared inbox so your team gets verification codes without sharing personal phones
Why Mercari rejects VoIP and prepaid numbers
Mercari's phone verification is a hard gate — no listing, no selling, no withdrawal without it. And Mercari's official Help Center is explicit about what it will not accept, with no exceptions offered.
- •Official Policy: VoIP, Prepaid, and International Numbers Blocked — Mercari's Help Center states directly: "Mercari is unable to verify international, prepaid, or VoIP phone numbers." This covers Google Voice, TextNow, Skype, Vonage, and every MVNO-based prepaid number. The error shown immediately is: "Please enter a valid mobile number."
- •"Phone Number Already Taken" Blocks Shared Numbers — Mercari enforces one account per phone number. If you try a shared or recycled number — common with disposable SMS services — Mercari will reject it with "This phone number is already linked to another account." Dedicated numbers avoid this entirely.
- •The 2FA Loop Trap — Users who set up their Mercari account with a number they no longer control find themselves locked out. Mercari requires SMS verification to access the account, but the number on file no longer works, and every VoIP alternative they try is rejected. The only exit is a fresh real-SIM number.
- •Income on the Line — Mercari is a primary side-hustle channel for thousands of resellers. An active account has accumulated buyer ratings, completed transaction history, and active listings — all of which disappear if the account becomes inaccessible due to a failed verification.
- •Re-Verification Triggers — Mercari may require re-verification after suspicious activity, device changes, or app updates. A long-term dedicated number means you are ready to re-verify in seconds without scrambling for a new one.
JoltSMS provides real-SIM numbers for legitimate Mercari account verification. Using numbers to create fraudulent accounts, circumvent suspensions, or violate Mercari's Terms of Service is prohibited and violates JoltSMS's terms as well.
How JoltSMS solves Mercari verification
JoltSMS provides real carrier SIM numbers from US mobile networks — not VoIP. Each number is dedicated to you alone so Mercari sees the kind of number it expects: a physical SIM backed by a real carrier.
- Real-SIM, non-VoIP numbers running on physical carrier infrastructure — the same kind Mercari expects, not a virtual cloud service like Google Voice or a prepaid MVNO that Mercari blocks
- Dedicated to you alone — your JoltSMS number is not shared with other customers during your rental. No "number already taken" errors from another reseller's history on Mercari
- Keep the number long-term — month-to-month rental means your number stays active for 2FA login codes, re-verification triggers, and account recovery
- Team access for reseller operations — share the inbox across your sourcing team so verification codes and 2FA alerts reach whoever needs them, with Slack, Discord, Email, or Webhook routing

Team-managed Mercari reseller operations
When a reselling operation manages multiple Mercari accounts — for consignment, client inventory, or internal brands — verification codes and 2FA alerts need to reach the right person without routing everything through one personal phone.
- Route Mercari verification SMS and 2FA codes to a shared Slack channel or team email so account managers can complete verification without depending on a single person being available
- If the person managing a Mercari account changes, the team still has access to the JoltSMS number — no locked-out accounts because a phone went with a departing employee or contractor
- Role-based access: Owners control billing, managers handle verification and notification settings, viewers monitor incoming codes — no one needs access to everything
- Set up Email or Discord notifications for async workflows so codes reach the right person the moment they arrive
