✕Common Mistakes
Sim, está o 305.
Use *ser* (é) for permanent identification, not *estar* which describes temporary states.
Sim, é um 305.
When a number functions as a noun you need the definite article *o*, not the indefinite *um*.
Sim é o 305.
A comma after *Sim* separates the affirmation from the statement and sounds more natural.

Cultural Tip
In Brazilian Portuguese, numbers that identify objects (rooms, buses, tickets) are treated as nouns and take the definite article *o* or *a*. Saying just “É 305” is also understood, but adding the article sounds more natural and slightly more formal. Avoid using *está* here; *ser* is the correct verb for permanent identification.
