Document types

Royal Decree 933/2021 accepts six identity document types for guest registration. Each has specific requirements that the form enforces automatically.

Available types depend on nationality

The guest picks their nationality first, and the form filters which documents they can select:

• Spanish nationality: DNI and Passport only.
• Any other nationality: Passport, Identity document from my country, NIE, EU registration certificate, and Travel document.

If the guest changes their nationality, the list re-filters.

The options are ordered by real-world use, the most frequent first, not alphabetically.

The form describes the chosen type

As soon as the guest picks a type, a sentence appears underneath saying exactly what that document is. It exists to prevent the costliest mistake on this step: choosing EU registration certificate when what they are holding is the national identity card of another EU country. That certificate is issued by Spain to resident EU citizens and carries a NIE number; another EU country's national card goes in as Identity document from my country.

Accepted types

Document	Who it's for	Last name 2	Support number
DNI	Spanish citizens	Yes	Yes
Passport	Any nationality	No	No
NIE	Foreigners with a Spanish residence permit	Yes	Yes
EU registration certificate	EU citizens resident in Spain	Yes	Yes
Identity document from my country	Any non-Spanish national using an identity document issued by a country other than Spain	No	No
Travel document	Refugees, stateless persons, special cases	No	No

Detail by type

DNI (Spain)

• Spanish National Identity Document. Spanish citizens only.
• Requires last name 2 and support number. If the guest has no second surname, they must enter a hyphen (-) in that field.
• The support number is printed on the front of the card, the photo side, and is three letters and six digits. The printed label depends on the document version:

Printed label	DNI version	Issued since
NUM SOPORTE	DNI 4.0	2 June 2021
NUM SOPORT (no final E)	DNI 3.0	2 January 2015
IDESP	Electronic DNI	16 March 2006

The CAN is not the support number

The unlabelled six-digit number at the bottom right of the front of the DNI is the CAN, which exists so an NFC reader can access the chip. It is not valid as a support number and the Ministry rejects it. This is the most common mix-up: full detail in Número de soporte del DNI (Spanish).

Passport

• International document accepted for any nationality, including Spanish.
• No second last name or support number required.

NIE (Foreigner Identity Number)

• For foreigners with a Spanish residence permit.
• Requires last name 2 and support number. If the guest has no second surname, they must enter a hyphen (-) in that field.
• On the TIE (tarjeta de identidad de extranjero) the support number is on the front, top right, in the same band that reads "Permiso de residencia". It carries no label beside it: it is the only block of an E followed by eight digits in that corner. The position is the same on the current European format (issued since 19 May 2020) and on the previous one (since 1 April 2011).

EU registration certificate

• For EU/EEA/Switzerland citizens resident in Spain. Spain issues it, and the number identifying the holder is a NIE. It is not another EU country's national identity card: that one goes in as Identity document from my country.
• Requires last name 2 and support number. If the guest has no second surname, they must enter a hyphen (-) in that field.
• The certificate comes in two formats, and the number is not in the same place as on the TIE:
  • Card format: the number is on the back.
  • Paper format (the older one): the certificate's own number serves as the support number, and it is on the front, top right.
• The Spanish administration's e-offices require that number to be written with a leading C and left-padded with zeros to eight digits: a certificate numbered 9999999 is entered as C09999999.

The C rule is not documented for SES.HOSPEDAJES

The C and left-zero-padding transformation is the entry rule for Cl@ve and the Spanish administration's e-offices. No official source confirms that SES.HOSPEDAJES expects the same format. If you regularly register guests with an EU registration certificate, confirm the format with SES.HOSPEDAJES support. Context in Número de soporte del NIE (Spanish).

Identity document from my country

• For any non-Spanish national using an identity document issued by a country other than Spain.
• No second last name or support number required.

Travel document

• Special documents issued by international bodies or by the Spanish Ministry to refugees, stateless persons, and other special cases.
• No second last name or support number required.

Why the requirements matter

Required fields are imposed by the Ministry of the Interior. If any are missing when a guest tries to sign, the form tells them which field is needed —the support number, or the second surname with the instruction to enter a hyphen (-) if they only have one— and blocks the signature until the field is filled.

The document number also has to match the chosen type. DNI, NIE, and the EU registration certificate carry a nine-character Spanish number with a check letter: if what the guest enters isn't shaped like that, the form does not let them continue and shows the expected format. When that option is available, it also points them at the type they probably meant, Identity document from my country — so "the number is mistyped" reads differently from "the document type is the wrong one". A passport, a travel document, and an identity document from another country have no format we can check, so those only get advisory warnings.
