The ADP tool doesn’t come with a manual, so you have to rely on online forums to understand error codes. Luckily, if you’re reading this article, we’ve done the work for you to resolve ADP error code 100.
If you’ve been researching HR solutions for your business, you’ve probably found ADP. ADP is one of the largest companies that provides human resources software and outsourced services to businesses.
It is a large company focused on providing software tools and outsourced HR services that businesses can use to more efficiently handle various human resources, payroll, and compliance functions related to their workforce. Rather than manage these HR processes in-house, organizations can hire ADP to handle these tasks for them.
However, some users have recently been running into errors on the ADP website and apps, especially during login, and various error codes, including one called error code 100, are causing confusion.
In this article, we’ll help you understand and fix ADP error code 100. We’ll explain when it happens, what the problem is, the possible reasons, and what you can do to fix it.
The main problem is that the error code 100 is not on ADP’s list of standard error codes. So there is no information available about what exactly this specific code means.
It seems the error 100 issue appears when there are temporary service disruptions or ADP server problems. So it may just be an intermittent glitch.
Since the specifics behind error code 100 are unclear, try some general troubleshooting steps to resolve it:
How to Fix ADP Error Code 100?
Wait for a few days if you are new
Sometimes the ADP error code 100 pops up when a newly created user profile hasn’t fully been added to the system yet. The details of a new ADP account, permissions, and access rules need to be synced with ADP’s servers.
This process can take a few days. If your profile’s not fully finalized yet in their systems, it could temporarily block logins and cause an unclear “error 100” message.
The simplest fix is just giving it more time. Wait at least a few more days and test if you can access your new ADP account again later. There’s a good chance the error 100 will disappear on its own once your profile finishes uploading properly from their end.
Try clearing your cache
Your web browser stores cache and cookies to help websites load faster on future visits. But over time, too much builds up. Lots of cached data take up memory space. This slows down your computer when using other platforms and apps.
To avoid login issues, make sure to regularly clear out the cache/cookies. It’s a good habit to clean the browser cache every so often.
Check your internet connection
When using online tools like ADP, first check that your internet connection is working properly. Sometimes the internet seems to be working fine based on other apps. But certain sites need faster, more reliable connections.
Do a quick test of your actual internet speeds. If speeds are low, that could cause ADP login issues and error messages. If after testing, your internet speeds are testing fine, then the ADP error is likely something else.
Switch to another browser
You might face a problem logging into ADP if you’re using a web browser that’s not compatible. If you think browser incompatibility is the issue, just switch to another web browser that works with ADP, and you should be good to go. Some known ADP-compatible options are Chrome, Firefox, and Edge.
Also, make sure to check if you have any browser extensions, like ad blockers or popup blockers, as they can sometimes cause issues with ADP.
Check login credentials
One common and easy reason for ADP login errors is entering incorrect credentials like passwords or usernames.
When passwords have capital letters, special symbols, and numbers – they become tricky to input precisely right each time. If you’re encountering ADP errors upon login, double and triple check you’re typing the proper username/email and password. It’s easy to make minor typos.
Make sure your account is not locked
Entering incorrect ADP login credentials too many times can get your account temporarily locked for security.
If you put in the wrong password 3 times, ADP systems may block access sensing suspicious/unauthorized attempts. Another common way your ADP account can get locked is simply not logging in for an extended period of time.
So if unsure of your password, immediately click the password reset option. Resetting it sends a password recovery email. This avoids accidentally typing the wrong one over and over.
Once locked out, you likely need to contact ADP support to unlock the account again. It may not be enough to simply reset the password at that point.
Ensure ADP servers are up and running
Sometimes ADP platforms can crash or be unavailable when too many users are active at once. Their servers get overloaded.
Scheduled maintenance periods can also cause temporary shutdowns. During maintenance windows, the site goes offline to update things behind the scenes.
When servers are down or overloaded, users will encounter login errors and access issues. But there’s nothing you can personally do to fix widespread technical problems across ADP’s systems.
In these cases, you’ll have to be patient until availability is restored. The problems are fully on ADP’s end rather than anything on your local device or network causing trouble.
You can try reporting problems to ADP support when servers crash. But usually, the technical teams are already working urgently to resolve crashes or finish up scheduled maintenance.
The core solution is to just wait it out, and then attempt accessing your ADP account when systems have recovered. With so many users, overloaded servers can happen despite their best efforts! Be patient and test again after a break.
Contact ADP support
If no other troubleshooting fixes the ADP error code 100, contact their customer support team directly. ADP has dedicated technical experts to help resolve account issues like persistent login errors.
Contact them and explain exactly when and how the error 100 appears for your user profile. A support representative can investigate why this unspecified error pops up and access solutions from the backend.
You can also check if other ADP users have posted about this error online. User forums may describe fixes that have worked for them.
