This depends on the specific provider's setup, but many rent reporting services do allow multiple tenants on the same lease to enroll individually, since credit files are personal rather than tied to a household. A few things worth clarifying with whichever service you choose:

How they handle a shared payment account. Since you're both paying out of one joint account, ask specifically how the service verifies "your" portion of rent when the underlying transaction is joint rather than split between two individual accounts.

Whether both of you get separate reporting, or just one primary tenant. Some platforms are built around a single primary tenant per unit; others explicitly support multiple co-tenants reporting independently. you can also use platform like tenantpay

Whether there's an added cost for a second person, since some services charge per enrolled tenant.

If your provider does support this, it's worth both of you signing up rather than just one — since credit history is individual, only reporting under one name means the other person misses out on that trade line entirely, even though you're both equally responsible for (and paying) the rent.

This is a good question to ask directly during sign-up rather than assuming either way, since the answer genuinely varies by provider and it affects whether it's worth one or both of you enrolling.
