How to register with SES Hospedajes step by step (2026)

In short

Registering with SES Hospedajes is free and is done at the Ministry of the Interior’s electronic office, inside the “Hospedajes y alquiler de vehículos” group, through “Acceso al registro de establecimientos y entidades”. You identify yourself with Cl@ve or a digital certificate and, to sign the registration, you need to be enrolled in Cl@ve Firma or have autofirm@ installed. You first register the entity (the arrendador) and then each establishment; once done, you have two separate credentials: the ones for signing in to the application and the web-service ones.

Before filing any report, turn on the “Envío de comunicaciones por servicio web” box under “Mis datos registrados” and note your lessor code, each establishment’s code and the web-service username. Catalonia and the Basque Country do not use SES Hospedajes: there, the report is filed with the Mossos d’Esquadra or the Ertzaintza.

Before you start

Gather this before entering the electronic office:

• ✓An electronic identification method: Cl@ve Móvil, the electronic DNI or a digital certificate, or Cl@ve permanente. To sign the registration you also need to be enrolled in Cl@ve Firma, or have autofirm@ installed if you are signing with a local certificate.
• ✓The holder’s (the arrendador’s) details, and the details of every property you are going to register.
• ✓An email address you check often: if you ever need to recover access to the application, the system asks for it together with your document number.
• ✓If you manage accommodations for several owners, be clear on which holder each property belongs to: each owner running their own activity registers as a separate entity.

Step 1. Open “Hospedajes y alquiler de vehículos” at the electronic office

The Ministry of the Interior’s electronic office groups this procedure under “Hospedajes y alquiler de vehículos”. Inside you will find three similarly-named accesses, and it is easy to confuse them:

Step 2. Enter through “Acceso al registro de establecimientos y entidades” and identify yourself

Press the “Acceso” button on the first block. It takes you to the Cl@ve identification gateway, where you choose how to prove your identity: Cl@ve Móvil, the electronic DNI or a digital certificate, or Cl@ve permanente.

If the electronic office will not let you in, check your certificate first: an expired one, or one installed in a different browser, is the most common cause.

Step 3. Register the entity (the arrendador)

The entity is the party obliged before the Administration: the company or person answering for the hospitality activity. The registration form is a five-step wizard — Tipo de registro, Datos de la entidad, Datos de los establecimientos, Revisar y firmar and Finalizar — and the first thing it asks is whether you are acting in your own name or as someone else’s representative.

The entity’s details are the tax and contact ones: document type and NIF, name or company name, entity type, activity type, address, province, municipality, postcode, email and phone, plus the email for web-service notices. The lessor code is not a field you fill in: the system assigns it once registration is complete.

If several owners run flats on their own —for example, you manage properties belonging to two different owners— each owner is a separate entity with its own registration, even if you operate both from the same tool.

Step 4. Register each establishment

With the entity created, register each physical accommodation separately: a flat, a rural house, a hotel. If you manage ten apartments, you register ten establishments under the same entity.

The establishment registration form asks for: name, establishment type (with a field to specify it if you choose “other”), number of rooms, whether it has an internet connection, contact email and phone, an optional additional phone, and an optional website.

A common mistake: the regional tourism registration number (the one starting with VT, VFT or your region’s equivalent) is not the Ministry’s establishment code. They are two different registers, and the SES Hospedajes code is assigned by the platform itself once you complete this step.

Step 5. Turn on “Envío de comunicaciones por servicio web”

Under “Mis datos registrados” → “Datos de la empresa” you will find the “Envío de comunicaciones por servicio web” box. Turn it on: it is what allows reports to be filed through the web service, whether from a connected tool or your own system.

If you leave it unticked, any attempt to file through the web service fails with a permissions error: the system returns code 10119 (“El arrendador no puede realizar ese tipo de comunicaciones”).

Step 6. Note your lessor code and your establishment codes

Under “Mis datos” → “Datos de la empresa”, the “Código” field is your lessor code. The Ministry assigns it once registration is complete: you do not type it in, you only look it up here.

Where to find each establishment’s code

In “Lista de establecimientos”, the first column shows each accommodation’s code. If you open its record with the view icon, the “Ver establecimiento” window repeats the same “Código” field.

Both codes —the lessor’s and each establishment’s— are 10 characters or fewer (for example, 0000000000). If the field in front of you takes more characters, or starts with VT or VFT, it is not the right code: it is the regional tourism registration number, a different register.

Step 7. Get the web-service username and password

Go to “Servicio de comunicación” → “Credenciales”. If your entity is the only one, you will see the web-service username directly; if you manage more than one entity, the system asks you to choose which. There you see the username, the name and the registration date — the password is never shown. The same screen has a section to download the service’s technical documentation.

The web-service username in practice usually ends in “WS”, but that can vary; check it on your screen. Do not confuse it with your personal application username, which is your document number: they are two different credentials, and a connected tool needs the web-service one, not the personal one.

How to change the web-service password

Press “Cambiar contraseña”: it asks for at least 8 characters, with an uppercase letter, a lowercase letter and a digit. On saving you will see “¡Contraseña cambiada!”, and the old password stops working at once, so update any connected tool as soon as you change it.

If you use BookCheckin: where each piece of data goes

BookCheckin asks for four values: the web-service username and password, the establishment code and the lessor code. The “Probar conexión” button confirms that the username and password authenticate correctly against the Ministry; it does not check the lessor code, which is only validated on the first real submission. BookCheckin does not register you with SES Hospedajes and does not generate any code: you get all four values from the steps above.

Common registration errors

After registration: the daily routine

Once registered, the daily obligation is to file one report per guest within a maximum of 24 hours from check-in. When a submission fails, it is almost always a specific field to fix, not a system outage.

Catalonia and the Basque Country

If your accommodation is in Catalonia or the Basque Country, this registration does not apply to you: the traveller report is filed with the Mossos d’Esquadra or the Ertzaintza, each with its own register and its own credentials.
