Consider using our free service that calls and talks to customer service for you, then sends you a report. Or use our free service that waits on hold and tells you when a human rep is on the line. But if those options don't appeal to you, our team has also documented the phone menu for LabCorp below.
Our AI powered phone can dial, navigate the phone menu, wait on hold, and even talk to customer service for you, for free. You don't even need to learn about the path through the various phone options.
That same, free GetHuman Phone can call and navigate the menus and wait on hold for you, but you can opt to do all the talking. We notify you when a rep is on the line and ready to talk, so no need to worry about changing menu options and weaving your way through the maze.
Of course, we completely understand if you prefer to do all the dialing, waiting, and talking yourself. All of these free tools are optional.

An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this LabCorp phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like LabCorp staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.
The least busy time to call
The least busy day to call LabCorp is Thursday.The most busy day to call is Monday, which averages 35% more phone calls by comparison.Again, this is based on a sample of 4,208 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold
We measured the shortest hold times to be on Wednesday.The longest wait in the queue on average occurs on Monday, which is 174% longer than the minimum.As you can see, there is more fluctuation in hold time over the course of the week than there is in call volume.
In summation, the best day to call LabCorp is Wednesday.It isn't the least busy day, but the fact that hold times are shortest combined with it being on the busy side tells us that LabCorp staffs up on Wednesday to handle the higher call volume, and that makes it the best time to call.

Information about why customers call LabCorp is extracted from issues that customers have reported to GetHuman.
Use the link to connect with customer service through Twitter
LabCorp, like many companies, provides customer service on the X platform (formerly Twitter). While it rarely entails live dialogue with a customer service rep, this channel can yield rapid response times and can be a useful option if you have an X/Twitter account.
As a last, sometimes only, resort- LabCorp customer service can be accessed through their website. This can entail digging through help articles before finding a form and "being allowed" to submit a problem to their team, and rarely leads to a real-time conversation, which is why GetHuman does not recommend this unless it's the only way.
