Players with a qualifying phone number whose rank is at least Lieutenant Rank 21 are eligible for Prime Matchmaking.
If you were previously upgraded to Prime and have lost that status, all you have to do is continue to play and earn XP. Once you reach Lieutenant Rank 21 you will again be eligible for Prime Matchmaking.
Prime Account Matchmaking excludes some types of phone numbers, such as VOIP numbers and some carriers. If your Steam phone number does not qualify, you'll be notified when you click the Upgrade button.
Please note that we cannot make any exceptions. Should your number not qualify, you will need to re-associate your CS:GO account with a qualifying phone number.
After reaching Lieutenant Rank 21 (profile level) click 'Play CS:GO' from the main menu. At the bottom of this screen click the 'PRIME ACCOUNT STATUS' button and you will be guided through the process of opting into Prime Matchmaking.
Yes, after upgrading a CS:GO account to Prime Matchmaking players have three days (72 hours) to upgrade a different CS:GO account using the same phone number. This will remove Prime Account Matchmaking from the original account the phone number was associated with.
After three days, players must wait six months before using the same phone number to upgrade a different CS:GO account to Prime Matchmaking.
If your Steam account has a phone associated with it, removing the phone will also remove CS: GO Prime Account Matchmaking. You are free to add a new phone number to the account, but the old phone number cannot be added to another account for Prime Matchmaking for six months.
To remove Prime Matchmaking from an account players must remove the current phone number associated with their Steam account. This removes Prime Matchmaking from their CS:GO account.
Note: the six month cooldown will still apply to the phone number before it can be added to another CS:GO account for Prime Matchmaking.
You may remove your old phone number from your account and add a new number at any time.
Note: The six month cooldown associated with activating CS:GO Prime Account Matchmaking is tied to the phone number that is used, not the Steam account.
No, the Steam Guard Mobile Authenticator is not required to activate Prime Account Matchmaking.
We still recommend that you use the Steam Guard Mobile Authenticator. In addition to providing an extra layer of security for your account, adding the Steam Guard Mobile Authenticator gives you full access to trading and the Steam Community Market.
