Joining Castelló de la Plana’s municipal population register is free, available year-round and completed in person. Booking is the straightforward part. Proving the address is where cases differ: a named tenant does not bring the same evidence as someone living in a home whose bills belong to another person.
The council splits the evidence into two questions. It first identifies everyone being registered, then checks that they actually live at the stated address. An appointment may not complete the registration if either part is missing.
Identity first, address separately
The council checks two separate facts: the identity of the applicant and whether that person actually lives at the address given. Applicants over 16 must provide an original identity document or an authentic copy. The municipal record distinguishes between a Spanish DNI; for EU and EEA citizens, an NIE together with a valid passport or national identity card; and, for other nationalities, a valid passport or Spanish-issued residence permit.
Children under 16 require a family book or birth certificate. If a child already has a DNI, the council’s information says the family book must also be provided. Family circumstances that cannot be covered by the usual signature of both parents may require the specific parental declaration available from the municipal electronic office.
The contract or bills determine whether authorisation is needed
If one of the applicants owns the home or is named on the tenancy, the address can be supported by a title deed or purchase contract, Land Registry note, IBI property-tax bill or current tenancy agreement. For a rented home, the council also asks for the latest payment receipt showing the landlord, tenant, payment period and address.
Electricity, gas or water contracts may also be used when they show the supply address and the contract holder’s full name. If none of the applicants appears on those documents, authorisation is required from the person who does. The appropriate form can be downloaded from the council’s official municipal-register page.
Plaça Major appointments can be booked online or by phone
An appointment is required to register at the General Registry in Plaça Major, 1. It can be arranged through the council appointment page, by calling 010 from Castelló or 964 226 010 from outside the municipality.
The procedure page also lists district registries at Plaça Primer Molí, Carrer Ricardo Catalá at Joaquín Márquez, Avinguda Germans Bou, Plaça Lagunas de Ruidera–Mas Blau and Passeig Buenavista in El Grau. As locations and opening hours may change, confirm the exact office while booking. The published general hours for district offices are weekday mornings, with shorter hours in summer.
Three details are worth checking before the visit: identity documents must be current, the address should match across the tenancy and receipts, and proof of rent must name the parties, payment period and home. Cases requiring authorisation also need the municipal form and the signer’s supporting document.
A move within Castelló is handled as a change of registered address, not a cancellation followed by a new registration. Once on the register, residents can obtain an individual note or certificate online. Cases outside the published examples can be raised through 010 or 964 226 010.
