If you mean the Marriott RSP inside a Fidelity workplace account , the account number is usually found in the Fidelity/NetBenefits account details or on plan documents , not in Marriott’s own Bonvoy profile. Fidelity’s support materials say you can see your Fidelity account number in the app under Home > Accounts, or on the web by logging in and looking at your accounts list.

For a workplace retirement plan, the number you need may actually be the plan number , not a personal account number. Fidelity notes that 401(k) workplace plans use a 5-digit plan number , and participants may need NetBenefits to view that information.

What to check

  • In the Fidelity app , open Home and scroll to Accounts ; your account number should appear there.
  • On the website , sign in and look at the accounts shown on the left side of the page.
  • If this is a 401(k)/workplace plan , go to NetBenefits and look for the plan details rather than expecting a standard brokerage account number.

If you still can’t find it

  • Check your statement , welcome letter , or plan documents.
  • Call Fidelity’s workplace plan support line at 800-835-5095.

Marriott note

If you were actually looking for your Marriott Bonvoy account number , Marriott says to log in, click your name, choose Profile , and the account number appears at the top of the page.

TL;DR: In Fidelity, look under Accounts in the app or web; for a workplace retirement plan, the identifier may be a plan number in NetBenefits rather than a regular account number.
