How to Get an SMS Code for Slack: Complete Guide to Online Verification

Posted on 08/07/26 08:00 am

Slack has become an essential communication platform for businesses and teams worldwide. Whether you're setting up a new workspace or logging into your account from a new device, Slack often requires SMS verification to ensure account security. In this guide, we'll walk you through exactly how to get an SMS code for Slack and receive it online without needing a physical SIM card.

Why Does Slack Send SMS Codes?

SMS codes are a critical security feature that Slack uses to verify your identity. When you sign up for a new Slack account or attempt to log in from an unrecognized device or location, Slack sends a verification code via SMS text message. This two-factor authentication method ensures that only authorized users can access your workspace, protecting sensitive business communication from unauthorized access.

Step-by-Step Guide to Getting an SMS Code for Slack

Method 1: During Slack Registration

Visit slack.com and click on "Sign up"
Enter your email address and create a password
Slack will send you a verification email—click the link to confirm
On the next page, you'll be prompted to enter your phone number
Enter your phone number and select your country code
Click "Send Code" to receive your SMS verification code
Enter the 6-digit code you receive via text message
Complete your workspace setup

Method 2: During Slack Login

Important Security Tips When Receiving Slack SMS Codes

Never share your SMS verification code with anyone. Slack employees will never ask for your verification code. If someone requests it, they're attempting to gain unauthorized access to your account.

Always verify that you're on the official Slack website (slack.com) before entering your phone number. Scammers sometimes create fake Slack login pages to steal verification codes.

If you're using a temporary phone number from SMS Code, keep in mind that codes are typically valid for a limited time. Enter your code promptly after receiving it.

If you're not receiving your Slack verification code, try these solutions:

Check your spam or junk folder for the text message
Verify that you entered the correct phone number
Wait a few minutes—SMS delivery can take time
