Updated November 10, 2026
Trying to play ROB RUN with friends but getting a message that they're on another server? The game's multiplayer system can be confusing, especially when switching servers requires Surrender to Feds, an option that can cost you your current inventory, cash, weapons, and base progress.
Fortunately, you don't always need to surrender to play together. If you and your friend are already on the same server, you can create a party directly without resetting your run.
This guide explains how to find your server number, join friends, switch servers through prison, send party invitations, and enter the same map together. You'll also learn what happens to your progress when surrendering and how to troubleshoot common multiplayer problems.

Quick Answer: How to Join Friends in ROB RUN
To play ROB RUN together, both players must be on the same server, join the same party, and enter the same playable map.
Follow these steps:
- Open the global map and find your server number in the upper-left corner.
- Ask your friend to check their server number.
- If the numbers match, press Tab → Party and invite your friend.
- If the numbers differ, one player must change servers through the prison system.
- Once you're on the same server, invite your friend using their player ID or Steam friends list.
- Travel to the map-selection area and choose Join Together.
Important: Do not select Surrender to Feds just because a party invitation fails. Surrendering can confiscate possessions from your current run. Always compare server numbers first.
Which Method Should You Use?
| Your situation | Best next step |
|---|---|
| Both players have the same server number | Create a party directly |
| Server numbers are different | Coordinate a server switch through prison |
| Friend joined the party but isn't visible | Enter the same map using Join Together |
| Party invitation isn't working | Check server codes and party status |
| Your friend's server is about to wipe | Check its remaining lifetime before switching |

How to Check Your ROB RUN Server Number
Before changing servers, check whether you and your friend are already connected to the same one.
- Open ROB RUN and bring up the global map.
- Look for the server code in the upper-left corner.
- Ask your friend to open their global map.
- Compare both server numbers.
If the numbers match, you're already on the same server. You can skip prison and move directly to the party invitation steps.
If the numbers differ, you're playing on separate servers. Being Steam friends doesn't automatically place you in the same world.
Check the Server Lifetime Before Switching
ROB RUN servers follow a seven-day lifecycle, and different servers can have different amounts of time remaining before their next Federal Raid.
For example, your server might have five days remaining while your friend's server has only one day left.
You can check the server's lifetime information from the initial jail or character screen when entering the game. Look for the displayed server age or remaining lifetime.
Tip: If your friend's server is close to its Federal Raid, consider whether you would rather wait for the reset or begin a new run together. Don't surrender valuable possessions without checking how much time remains.
How to Join Friends Without Changing Servers
If both players have matching server numbers, you can create a party without using Surrender to Feds.
Here's how:
- Make sure both players are connected to the same server.
- Return to the global map or an area where party invitations are available.
- Press Tab to open the menu.
- Select Party.
- Invite your friend through their player ID or Steam friends list.
- Ask your friend to accept the invitation.
- Check that their name appears in the party interface.
- Once your friend appears in the party, you can travel to map selection and enter a location together.
Remember that being on the same server, being in the same party, and entering the same map are three separate steps.
If your friend is already on your server but isn't visible, don't surrender. Check the party and map-selection steps first.
How to Change Servers in ROB RUN Using Surrender to Feds
If your friend is on a different server, ROB RUN uses the prison system to let players change servers.
This process is different from a normal server transfer because surrendering ends your current run and can result in losing possessions.
Step 1: Understand the Surrender Warning
Before changing servers, consider what you've accumulated.
Surrendering can confiscate cash, weapons, inventory, vehicles, and property associated with your active run.
If you've spent several days collecting equipment or building a base, decide whether joining your friend's server immediately is worth that loss.
Step 2: Surrender to the Feds
You can access the surrender option through either of these menu paths, depending on your current interface.
Method 1 — Settings Menu
- Open Settings.
- Select Other.
- Choose Surrender to Feds.
- Read the warning.
- Confirm only when you're ready to end your current run.
Method 2 — Global Map
- Open the global map.
- Select Prison.
- Choose Surrender to Feds.
- Review the consequences.
- Confirm your decision.
Both methods take you into the prison system, where server switching becomes available.

Step 3: Find the Server Selection Room
After entering prison:
- Look for a room with a poster on the wall.
- Enter the room and locate the server-selection interface.
- Open the list of available servers.
- Find the server number your friend is using.
If both players are starting fresh, you can choose a destination server and share its number before either player joins.
Step 4: Join Your Friend's Server
- Ask your friend for their exact server number.
- Enter it into the server search field.
- Select the matching server.
- Verify the number before proceeding.
- Click Confirm.
Once the switch is complete, check that your server number matches your friend's.
Important: Agree on the destination server before anyone surrenders. Otherwise, both players could end up switching to different servers and still be unable to play together.
How to Invite Friends to Your ROB RUN Party
After both players are on the same server, create a party.
Step 1: Open the Party Menu
Press Tab on your keyboard, then select Party.
Step 2: Send the Invitation
ROB RUN supports party invitations using:
- Player ID: Enter your friend's in-game ID.
- Steam friends list: Select your friend using the available Steam invitation option.
Your friend must accept the invitation before joining the party.
Step 3: Confirm Your Friend Joined
After the invitation is accepted, your friend's name should appear in the party interface, typically near the bottom of the screen.
If their name doesn't appear, check whether the invitation is pending and confirm that both players are on the same server.
Once the party is formed, you can proceed to map selection.
How to Enter the Same Map Together in ROB RUN
A successful party invitation doesn't automatically mean both players are standing in the same playable location.
To enter a map together:
- Confirm that both players appear in the party.
- Travel to the map-selection area.
- Open the destination or map list.
- Choose the location where you want to play.
- Select Join Together.
- Wait for both players to finish loading.
Once both players enter successfully, you can explore and complete missions as a team.
Why Can't I See My Friend Even Though We're in a Party?
First, check whether you're both in the same playable map.
If one player entered a destination separately, the party may be formed without both players occupying the same location.
Return to map selection, confirm that the party is still active, and use Join Together.
If one player gets stuck loading, check the troubleshooting steps below before considering any server change.
What Happens to Your Progress When You Surrender?
Surrendering to the Feds can cause you to lose possessions and progress tied to your current server run.
ROB RUN separates temporary server possessions from persistent character or account progression. Some progression is intended to carry forward, while items accumulated during the active run may be confiscated.
What Do You Lose and Keep?
| Progress or item | Typical surrender outcome |
|---|---|
| Cash earned during the current run | Confiscated |
| Weapons and carried inventory | Confiscated |
| Base and claimed property | Lost with the current run |
| Vehicles and other current-state assets | Not transferred |
| Authority progression | Generally retained |
| Tattoos and persistent unlocks | Generally retained |
| Purchased cosmetics | Generally retained |
| Premium currency and account purchases | Generally retained |
These are the expected distinctions between current-run possessions and persistent progression. The exact treatment of individual items may vary, so always read the in-game surrender confirmation screen before proceeding.
Can You Switch Servers Without Losing Your Items?
If you and your friend are already on the same server, you can invite each other without surrendering.
If you're on different servers, the documented switching method uses the prison system. There is no established method for transferring an entire active run, including your base and inventory, to another server without surrendering.
Can You Recover Progress Lost After Surrendering?
Don't assume that items confiscated during a voluntary surrender can be recovered.
If you confirmed Surrender to Feds, the loss may be an intended part of the game's progression system.
However, if your items disappeared without surrendering or a scheduled Federal Raid, you may be dealing with an unexpected rollback or technical issue.
In that situation, contact ROB RUN Support: Kefir Games ROB RUN Support and provide your server information and a description of what disappeared.
ROB RUN Friend Invite Not Working? Try These Fixes
If you still can't join friends, identify the exact issue before changing servers again.
| Problem | What to check |
|---|---|
| Friend is on another server | Compare server codes |
| Can't find friend's server | Search using the exact server number |
| Party invitation doesn't appear | Return to the global map and reopen Party |
| Friend cannot accept invitation | Check party status and try a fresh invitation |
| Friend is in the party but invisible | Enter the same map using Join Together |
| One player is stuck loading | Check whether the other player entered successfully |
| Progress disappeared after switching | Check whether surrender caused the loss |
Fix 1: Check Both Server Numbers Again
If an invitation fails, ask both players to open the global map and compare server codes.
Don't assume a previous server switch was successful until the displayed numbers match.
Fix 2: Invite From the Global Map
If both players are on the same server, return to the global map and try sending the invitation again.
This helps separate party-invitation issues from problems with a particular playable location.
Fix 3: Reopen the Party Menu
Press Tab → Party and check whether your friend is already listed.
If the invitation is pending or no longer visible, try sending a new one.
Fix 4: Use Join Together Instead of Entering Separately
If your friend appears in the party but isn't visible in the game world, return to map selection.
Choose the same destination and use Join Together.
Fix 5: Friend Joined the Party but Is Stuck on the Loading Screen
If one player gets stuck while entering a map:
- Check whether the other player successfully entered the destination.
- Confirm that both players selected Join Together rather than entering separately.
- Wait briefly to see whether loading completes.
- If the game remains unresponsive, restart the affected client.
- Recheck the server number and party membership after reconnecting.
- Try entering the destination together again.
A restart may help with a temporary loading problem, but it won't resolve every server-side issue.
Do not surrender again simply to fix a loading screen. Doing so may cause additional progress loss without solving the underlying problem.
Fix 6: Check for Server Problems
If both players are on the correct server but party invitations or map loading repeatedly fail, the issue may be related to server connectivity.
You can check the ROB RUN Steam Discussions: ROB RUN Steam Discussions for other players reporting similar problems.
If multiple players are experiencing the same issue, restarting repeatedly may not help until server stability improves.
How Seven-Day Server Wipes Affect Playing With Friends
ROB RUN uses a seven-day Federal Raid cycle that resets temporary server progression.
This is different from voluntarily surrendering to switch servers.
Does Every ROB RUN Server Wipe at the Same Time?
No. Servers have their own lifecycles, meaning their Federal Raid countdowns can differ.
For example, one server may have two days remaining while another has five.
This is why you should check your friend's server lifetime before surrendering to join them.
What Happens During a Federal Raid?
When a server reaches the end of its cycle, the Federal Raid resets temporary assets accumulated during that run.
This can include bases, weapons, cash, and other current-state possessions. Certain persistent character progression and account unlocks remain.
Should You Surrender or Wait for the Wipe?
The decision depends on how much progress you have and how soon your current server is scheduled to reset.
If you have valuable possessions and only a short time remains before the Federal Raid, waiting may be more convenient than surrendering immediately.
If your friends are starting on a different server, you can also coordinate a fresh run together.
However, don't assume that surrendering early and waiting for the Federal Raid provide identical jail-time calculations or progression rewards.
Best approach: Check both servers' remaining lifetimes, agree on a destination, and understand what you'll lose before switching.
Frequently Asked Questions
How do I join my friend in ROB RUN?
Open the global map and compare server numbers. If they match, press Tab → Party and invite your friend using their player ID or Steam friends list. Once the invitation is accepted, travel to map selection and choose Join Together.
Can I join friends without surrendering to the Feds?
Yes, if both players are already on the same server. You can create a party directly. If you're on different servers, the documented server-switching process requires using the prison system, which can result in losing current-run possessions.
Why does ROB RUN say my friend is on another server?
Your friend is connected to a different server instance. Compare your server codes on the global map. If the numbers differ, coordinate a server change before attempting to join the same party.
Do I lose everything when changing servers?
Surrendering can confiscate cash, weapons, inventory, and property associated with your active run. Certain persistent progression, cosmetics, and account unlocks generally remain. Always review the surrender confirmation before proceeding.
Where can I find my ROB RUN server number?
Open the global map and look for the server code in the upper-left corner. Share the exact number with your friend so you can confirm you're both connected to the same server.
How do I find my friend's server in prison?
After surrendering, locate the room containing the server-selection poster. Open the server list, enter your friend's server number into the search field, select the matching result, and confirm.
Can I invite friends through Steam?
Yes. Open Tab → Party and use the available Steam friends invitation option. You can also invite another player using their in-game player ID.
Why is my friend in the party but not visible?
You may be in the same party but different playable maps. Return to map selection, confirm both players are still grouped, and select Join Together to enter the same destination.
Does every ROB RUN server wipe simultaneously?
No. Servers follow separate lifecycles, so their Federal Raid countdowns may differ. Check the remaining lifetime of the server you're planning to join rather than assuming every server resets on the same date.
Can I recover items after surrendering?
Items confiscated through voluntary surrender should not be assumed recoverable. If possessions disappeared unexpectedly without surrendering or a scheduled wipe, contact ROB RUN support with your server details and a description of the missing progress.
Final Checklist: Join Friends Without Unnecessary Progress Loss
Before starting your next multiplayer session, confirm these four things:
- Matching server numbers: Both players are connected to the same server.
- Party confirmed: Your friend's name appears in the party interface.
- Same map selected: Both players use Join Together.
- Surrender risks understood: Anyone changing servers knows what may be lost.
The most important rule is to check your server number before surrendering to the Feds.
If you're already on the same server, skip prison and create a party directly. If you're on different servers, coordinate the destination and check the server lifetime before giving up your current run.
With the correct server, party, and map selected, you can get back to completing missions and playing ROB RUN with your friends.
