#LinkedIn Verification Phone Number Error – Troubleshooting Guide

The LinkedIn verification phone number error usually happens when LinkedIn can't deliver an SMS to your number, or when the code expires before you enter it.

Check that your number is in the correct E.164 format, that you have cellular signal, and that you haven't accidentally blocked LinkedIn's shortcode. If the code doesn't arrive within 60 seconds, request a new one.

Troubleshooting Checklist:

• Check signal strength: No signal means no SMS. Move somewhere with better reception.

• Shortcode blocking: Some carriers block automated SMS from non-standard numbers. Check your phone settings or contact your carrier.

• Do not disturb mode: Make sure your phone isn't in a mode that silently intercepts SMS notifications.

• Code expiration: LinkedIn codes typically expire within 10 minutes. Request a fresh one if you waited too long.

• Number already in use: LinkedIn may reject a number tied to another account, active or dormant.

If your carrier is blocking LinkedIn's shortcode or your number is already in use, SMSPin's temporary numbers are pre-validated and work with hundreds of services. Pay only $0.01+ per successful code automatic refund if nothing arrives.

#What to Do When LinkedIn Says Phone Number Not Accepted (New Account)

When LinkedIn says your phone number not accepted during new account creation, it's often because the number is already associated with an existing account, or your formatting is off.

First, try the exact E.164 format. If that fails, the number might be flagged as invalid by LinkedIn's carrier database especially if you're using VoIP or burner numbers.

• Try a different number if possible especially a mobile number from a major carrier.

• Avoid VoIP or Google Voice numbers. LinkedIn may block them due to spam concerns.

• Use a number from a supported country (LinkedIn is strict on some regions).

• Choose wisely: Free numbers backed by real SIM cards generally have a higher verification success rate than app-based or VoIP numbers.

• Wait 24 hours before retrying with the same number to avoid rate-limiting issues.

#LinkedIn Phone Number Country Code Not Accepted? Try These Fixes

If LinkedIn says your phone number country code not accepted, it's usually because the country code you entered doesn't match LinkedIn's supported list, or you used an incorrect prefix.

Check that you're using the correct country code (e.g., +1 for the US, not 001). Sometimes users accidentally use 0 instead of + at the start.

• Double-check country codes using a reliable international dialling code list.

• Never start with double zeros (00) always use the plus sign (+) as the international dialling prefix.

• Some countries have multiple codes (e.g., +1 for both the US and Canada). Make sure you select the correct region if prompted.

• LinkedIn may not support certain small, new, or disputed countries. If your country falls into this category, you may need an alternative number.

• If your country is supported but still fails, try a different mobile network in your country.

#How to Test LinkedIn SMS Verification Without Your Real Number

Testing LinkedIn's SMS verification flow without exposing your personal number is straightforward with a temporary virtual number.

Platforms like SMSPin provide real SIM-based numbers that can receive LinkedIn verification codes instantly. You pay per use (pricing starts from $0.01), and if a code doesn't arrive, you get an automatic refund.

Steps to use a temporary virtual number:

• Choose a temporary number from a country LinkedIn supports (e.g., US, UK, India).

• Enter the number in LinkedIn using the correct E.164 format.

• Wait for the SMS to appear in your virtual inbox (usually within 30 seconds).

• Copy the code and complete LinkedIn's verification.

• The number is disposable giving you enhanced privacy by not linking to your real identity.

#LinkedIn Registration Phone Number Problem: Advanced Solutions for Developers

For developers automating LinkedIn account creation or testing, the LinkedIn registration phone number problem often stems from rate-limiting or carrier-specific blocks.

LinkedIn may reject numbers from known VoIP ranges. Using a real SIM-based number through SMSPin's API allows you to programmatically request numbers and poll OTP status, bypassing common blocks.

Developer Solutions:

• Use SMSPin's developer API to request a number and receive the SMS programmatically, integrating directly with your automation scripts.

• Rotate numbers between attempts to avoid LinkedIn's rate limits, which can flag sequential requests from the same number as suspicious.

• Ensure the number is from a mobile carrier, not a VoIP provider, as LinkedIn prioritizes verifying with traditional mobile numbers.

• Poll the OTP endpoint every 5 seconds until the code arrives, ensuring timely retrieval and use.

• If you receive SMS successfully, note the exact phone number format you used. It can help you repeat the setup and spot any LinkedIn formatting requirements.

 

#Why a Temporary Number for LinkedIn Verification Makes Sense (and When Not to Use One)

Using a temporary number for LinkedIn verification protects your personal phone from marketing lists and unwanted contact. It's smart for quick signups, testing, or when you don't want to link your main number.

But here's the truth: don't use a temp number for a permanent LinkedIn account you rely on. If you lose access to the number, you may have trouble recovering the account later.

SMSPin offers both one-time use ($0.01+) and number rentals (1 day to 1 month) for users who need longer-term access.

Considerations for Temporary Numbers:

• One-time numbers are great for single verifications or testing. They serve their purpose and are then discarded.

• Rent a number if you need ongoing access for account recovery, receiving two-factor authentication (2FA) codes, or maintaining a number for an extended period.

• Never use a temporary number for a LinkedIn account tied to critical business operations where long-term, uninterrupted access is essential.

• Keep a record of the number you used if you plan to keep the account, along with any associated recovery information.

Rent a number for 1 day to 1 month if you need ongoing LinkedIn verification or account recovery. SMSPin is independent of LinkedIn always follow the platform's terms and local regulations. 

#Key Takeaways:

• The LinkedIn phone number format not accepted error is typically a formatting issue.

• Always use the E.164 format: +[country code][national number] without any spaces, hyphens, or parentheses.

• Avoid VoIP numbers as LinkedIn often flags them.

• Temporary virtual numbers offer a privacy-conscious way to verify LinkedIn accounts or test the verification process.

• For critical accounts, ensure you use a number to which you have permanent, reliable access.
