Request your rental registration number

Through a single registration procedure, located in the Property Registry and Real Estate Registry, you can obtain a unique registration number, the Rental Registration Number. This number, assigned to each property or partial unit, allows you to advertise your property on short-term rental online platforms (Rentalia, Booking, Airbnb, etc.).

From June 2025, obtaining one will be essential for tourist rental properties wishing to advertise on online platforms. We can help you with the entire process.

¡No puedo elogiar lo suficiente a Estefanía de Black Otter! Ella ha sido una roca desde que decidí comprar un apartamento en España. Ella me ha ayudado durante todo el proceso, desde obtener un número NIE y una cuenta bancaria española, hasta cerrar el trato de propiedad, configurar débitos directos, pagar impuestos y ahora hacer mis declaraciones anuales. No hay pregunta demasiado pequeña o demasiado estúpida que Estefanía no responda de inmediato, ¡y siempre de manera amigable y servicial! Adquirir una casa de vacaciones ha sido sin complicaciones ¡gracias a Estefania!.Nina

Professional, reliable and capable. Estefania has helped me with several things and always resolved the things I needed help with.Martin
