LinkedIn SMS Verification
LinkedIn requires SMS verification for new accounts and sensitive security changes. SMSTwins provides real SIM-backed numbers with automatic OTP parsing and refunds when routes fail.
LinkedIn typically sends a 6-digit numeric SMS code during registration and phone-change flows.
How LinkedIn verification works
- 1. Create an account — Sign up and top up your SMSTwins balance (card or crypto).
- 2. Select LinkedIn — Choose your country; live stock and price shown before purchase.
- 3. Enter the virtual number — Paste it into LinkedIn during signup or the verification prompt.
- 4. Receive your OTP — Code appears in your dashboard, API, or webhook — parsed automatically, no manual SMS reading.
Why non-VoIP numbers matter
Professional networks filter low-quality and VoIP ranges. SMSTwins routes LinkedIn activations through physical SIM inventory with provider quality scoring.
Tips for reliable delivery
- Use a country that matches your professional profile region when possible.
- Enter +country code in LinkedIn's picker before local digits.
- For long-lived accounts, consider renting a dedicated line instead of a 30-minute activation.

Automatic refunds & pricing
Activations last 30 minutes. If no SMS arrives, your balance is refunded automatically — no support ticket needed. You can also cancel manually after 1 minute if you need to switch country. Loyalty rank discounts apply to your purchase price on all activations.

Automate LinkedIn verification with the SMSTwins REST API — request a number, capture OTP via webhooks, and cancel after tests. Never use personal SIMs in CI pipelines.
