Marriott MMP Account Linking: How It Works

Account linking connects eligibility to the Bonvoy account number submitted during setup. Once linked, that account is the one that should be used to search with MMP. The goal is to make the booking path consistent from search to reservation to check-in.

This is different from simply knowing the MMP code. Many people can type MMP into a search box, but the booking system still needs to decide whether the signed-in account is eligible and whether a hotel has inventory. Linking addresses the eligibility side of that equation.

A Bonvoy account number is a unique identifier. Email addresses can change, names can be spelled differently, and households can manage several accounts. The number gives setup teams a cleaner target for the account that should receive access.

If the wrong number is submitted, the traveler may search from the intended account and see nothing. That does not necessarily mean MMP is unavailable; it may mean access was tied somewhere else. Before submitting an order, copy the number directly from the Bonvoy profile whenever possible.

Sign in to the exact Bonvoy account that was linked. Search one destination, one room, and a flexible set of dates if you are testing for the first time. Enter MMP in the special rate field before running the search.

If the rate appears, book directly through Marriott. If the rate does not appear, run a controlled test with nearby hotels and date changes. Account linking creates eligibility, but hotels still control whether discounted inventory is open for a particular stay.

The most common issue is using the wrong account. A traveler may have an old Bonvoy profile, a new profile, and an app session that stayed logged into one of them. Always compare the account number shown in the profile with the number submitted for setup.

Another issue is searching too soon or assuming every property will show MMP. Wait for setup confirmation, then test several properties. If nothing appears, send support the Bonvoy number, confirmation email, search dates, and hotel examples so the issue can be diagnosed with evidence.

Only provide the information needed for setup. VoyagePass asks for the Bonvoy account number, relationship selection, and delivery email because those details support account linking and communication. We do not need your Marriott password to help with setup.

Accuracy protects your order. Names, account numbers, and emails should be checked before payment. A small typo can create a real delay, especially if the team has to confirm whether a digit belongs to the correct traveler.
