Enrolling is easy

The Mercer Marketplace 365+ website will guide you through the benefits enrollment process every step of the way.

iconLog in

Go to the Mercer Marketplace 365+ website.

  • If you’re a returning user: Log in with your username and password.
  • If you’re a first-time visitor: Select “Get Started” and follow the instructions to register your account. You’ll need to provide the last four digits of your Social Security number, your last name, your date of birth, and your ZIP code. Then click the “I’m not a robot” box. (Note: When setting up your account, your username must be an email address.)
  • All users will be asked to select an email address or phone number for multifactor authentication (MFA), a security measure that ensures a higher level of data protection. MFA combines your username and password with an additional security factor — a temporary numeric code sent to you — to confirm your identity and keep your information secure. Simply enter this code into the site once you receive it via email or text.

New Hires

Welcome to your Parexel benefits!

As you consider the right benefits for you and your family, take the time to review what you’ll pay for 2021 based on the plan you select:

Life events

Except for benefits such as your Health Savings Account (HSA) or 401(k) plan, which you can adjust at any time during the year, you may not change or cancel your benefit elections during 2021 unless you experience a qualifying life event. Otherwise, your next opportunity to change your benefits will be the next Open Enrollment period.

Qualifying life events include but are not limited to:

  • Marriage
  • Divorce or legal separation
  • Birth or adoption of an eligible child
  • Death of your spouse or covered child
  • Loss or addition of other group coverage
  • Change in your spouse’s work status (part time to full time or vice versa; taking or returning from an unpaid leave of absence)
  • Change in your work status that affects your benefits
  • Change in residence that affects your eligibility for coverage
  • You or your covered dependent becomes eligible for Medicare

What to do if you experience a life event
If you need to make changes to your 2021 benefit elections as a result of a life event, visit the Mercer Marketplace 365+ website or call a benefits counselor at 1-866-696-8683. Changes must be made within 30 days of your qualifying life event. Changes are effective as of the date of the event.
