In the ever-evolving battle against cheating, PUBG: BATTLEGROUNDS has consistently refined its defenses. Back in November 2023, the Anti-Cheat Team released a comprehensive Dev Letter outlining significant enhancements to the Ranked authentication system. Fast forward to 2026, and these measures remain a cornerstone of the game's integrity framework. But what exactly prompted these changes, and how do they impact players today? Let's delve into the details.

The Background: Why SMS Wasn't Enough

When Ranked mode launched in May 2021, PUBG introduced an SMS authentication system. Every player had to confirm their mobile number to access Ranked, a barrier designed to deter cheaters. Additionally, the system prevented the reuse of mobile numbers previously linked to permanently banned accounts. For a while, this worked. However, internal analysis based on multiple data sources revealed a troubling trend: cheaters in certain regions were exploiting proxy authentication techniques to bypass the system. In other words, the SMS barrier was no longer sufficient to keep banned players out of Ranked. The Anti-Cheat Team knew they needed a stronger, more adaptive solution.

The Solution: ARS Authentication and Re-Authentication

To combat proxy authentication effectively, PUBG rolled out two key enhancements on November 15, 2023:

  1. Introduction of ARS authentication – Instead of (or in addition to) SMS, players may be asked to verify via an automated phone call that delivers a PIN code.

  2. Requirement to re-authenticate with the same number – Accounts that previously authenticated for Ranked can be asked to re-verify using the exact mobile number they used before. Attempting to authenticate with a new number will fail.

These changes are not universally applied. They are selectively employed in cases deemed necessary to uphold a fair gaming environment and safeguard player accounts. So, who might be asked to re-authenticate?

Scenario Description
🚨 Suspected compromised accounts Accounts that may have been accessed by unauthorized users.
⏳ Long-term inactive accounts Players returning after a significant break.
🤖 System-determined cases Accounts flagged by internal systems as needing re-verification.
🖥️ PC or connection region changes Sudden shifts in hardware or network location may trigger re-authentication.

What Players Need to Know

If you're asked to re-authenticate, here's the process: you'll receive an ARS call with a PIN code. You must complete this step before you can play Ranked again. Importantly, you can only use the mobile number you originally used for authentication. If you try a new number, the system will block you. This strict rule prevents cheaters from simply swapping numbers to regain access.

But what if you no longer have access to that old number? The Anti-Cheat Team addressed this in a helpful FAQ.

Frequently Asked Questions

Q: I'm not receiving the phone call with my PIN code.

A: First, double-check that you entered your mobile number correctly. If it's correct, your phone carrier might be blocking the outgoing ARS authentication number. Review your blocked numbers list and unblock the number, then try again.

Q: I was asked to authenticate with my old number, but I changed or lost it. Can I still play Ranked?

A: Yes, but you'll need to contact PUBG Support. Provide a screenshot of the ARS authentication message (see example below) along with your account information. After review, support will help you authenticate your new number for Ranked.
