NUT (Número Único de Trámite) (Unique Procedure Number)noot (NOO-meh-roh OO-nee-koh deh TRAH-mee-teh)
NUT is a unique tracking number assigned by the Instituto Nacional de Migración (INM) to each immigration procedure filed by a foreign person in Mexico. The NUT identifies a specific procedure and changes with each new application, unlike the permanent Número Único de Extranjero (NUE) that identifies the individual.

How it works
A foreign buyer, owner or renter receives a new NUT each time they file an immigration procedure at INM: applying for temporary residency, permanent residency, renewal, address change or other matter. The applicant first completes an online Formato Básico through the INM Micrositio de Trámites and prints it. The formato is valid for 90 days from creation. Upon presenting the printed formato and supporting documents at an INM office window, the officer registers the application and issues an electronic receipt bearing the NUT for that specific procedure. In Quintana Roo, INM offices operate in Cancún (Av. Carlos Nader, SM 5), Playa del Carmen (Av. Constituyentes at Av. 95), Chetumal and Cozumel. Appointment wait times typically range from one to three weeks during high season (November through March), with professional services reporting 24 to 72 hours. The NUT enables the applicant to schedule an appointment at citas.inm.gob.mx (free), track the procedure status online and request an official Constancia de Trámite if processing extends for months. Example fees: a one-year temporary resident card costs 11,141 pesos in 2026; a two-year card 16,693 pesos. Each procedure generates a new NUT; a person may have multiple NUTs over time but only one NUE.
