Digital certificates for companies and representatives

Every certificate your company needs, issued and renewed without visiting an office.

A company handles several types of certificates depending on who is acting and for what purpose: representative of a legal entity, sole or joint-and-several director, representative of an entity without legal personality, company seal for automated invoicing, and public employee certificates. Choosing the wrong one can cost you weeks, since each requires different supporting documentation.

Frequently asked questions

How long does it take for my digital certificate to be active?

The complete process is usually completed in 24-48 hours from when we verify your identity. Once issued by the certification authority, you can download and install it immediately to start using it in your procedures.

In urgent cases, we can expedite the process so you have your certificate operational the same business day, as long as you complete identity verification during office hours.

Is the digital certificate mandatory for online procedures?+

For most procedures with public administrations, yes it is mandatory. The Tax Agency, Social Security, official registries, and many entities require a digital certificate or equivalent systems like Cl@ve PIN to access their electronic services.

It is the safest and most practical way to identify yourself online, as other systems like Cl@ve PIN have usage limitations and more restricted functionalities.

Can I use my certificate on multiple devices?+

Yes, you can install your digital certificate on multiple devices: computers, laptops, tablets, and smartphones. We provide you with detailed instructions for each type of device and operating system.

We recommend exporting it to a secure file so you can easily install it on new devices when needed, always maintaining maximum security with password protection.

What legal validity does signing with a digital certificate have?+

The electronic signature made with a recognized digital certificate has the same legal validity as your handwritten signature according to European legislation (eIDAS Regulation) and Spanish law (Law 6/2020).

It is fully valid before courts, notaries, public administrations, and private entities. Digitally signed documents are admissible as evidence in legal proceedings.

How much does getting a digital certificate with notarial advisory cost?+

The price depends on the type of certificate and the level of advisory you need. Individual certificates with basic support cost from 60 euros, while business certificates or those with complete advisory may vary.

We include identity verification, complete processing, guided installation, and technical support. Request a personalized no-obligation quote through the form.

What happens if I lose my certificate or change computers?+

If you exported your certificate to a security file (.pfx or .p12 format), you simply install it on the new device using the password you set. We teach you to make this backup from the beginning.

If you lost it without making a copy, you will need to revoke the previous certificate and request a new one for security. We manage the entire revocation and renewal process.

How long is a digital certificate valid?+

Individual digital certificates have a validity of 4 years from issuance. Company certificates usually have a validity of 2-3 years depending on the issuer.

We notify you before expiration to renew your certificate with sufficient time to avoid interruptions in your procedures. Renewal is faster than initial issuance.

Can I use my digital certificate outside of Spain?+

Certificates issued by recognized Spanish authorities work throughout the European Union thanks to the eIDAS Regulation that guarantees mutual recognition between member countries.

For procedures with administrations in other EU countries, your Spanish certificate is valid. Outside the EU, it depends on bilateral agreements and local legislation of each country.

What is the difference between a digital certificate and electronic ID?+

The electronic ID (DNIe) includes a digital certificate integrated into the chip of the physical document. It requires a specific card reader to use on a computer, which limits its practicality.

The digital certificate is installed directly on your devices without the need for additional hardware, is more convenient to use, and you can carry it on your mobile. Both have the same legal validity.

Is it safe to store my digital certificate on my computer?+

Yes, as long as you take basic precautions: use strong passwords, keep your operating system updated, and have an active antivirus. The certificate is protected with a private password that only you know.

We recommend keeping backup copies on encrypted external devices or USB drives stored in a safe place. Never share your password or send your certificate by email without protection.

Which certificate does my company need?+
It depends on the intended use: the legal entity representative certificate covers almost all procedures; the sole or joint director certificate is a variant with simplified accreditation; and the company seal is used for automated processes such as electronic invoicing, with no individual behind it. It's often advisable to have both a representative certificate and a seal.
What is a company seal and when do I need one?+
It's a certificate belonging to the entity itself, not to a person. It's used to automatically sign invoices or bulk documents from a computer system. If you invoice manually, you don't need it.
Can I hold several certificates at the same time?+
Yes, and in companies with multiple authorized representatives this is standard practice. Each person must use their own: sharing a certificate is risky and goes against the provider's policies.
What should I do if it expires in the middle of a busy period?+
Online renewal is only possible while the certificate is still valid. If it has already expired, the full accreditation process must be repeated, which takes several days. Let us know in advance and we'll renew it before it expires.
What if the certificate is compromised?+
Immediate revocation and issuance of a new one. We handle urgent revocations the same day: a certificate in the wrong hands allows someone to act on the company's behalf before any government authority.
Do documents signed online have the same validity as those signed in person?+
Exactly the same. Law 11/2023 recognises the full legal validity of notarial documents executed by video call with a qualified electronic signature before a registered notary.
Do I need a digital certificate?+
Yes, to sign electronically you need a digital certificate or an electronic DNI. If you do not have one, we help you obtain it quickly before your appointment, with no additional handling fee.
Can I do it from abroad?+
Yes, the notarial video call works from any country. You only need a stable connection, your valid identity document and a digital certificate.
How much does this service cost?+
The quote includes the official notarial fees set by the Notarial Association plus our handling, fixed before you start and with no hidden costs. Request it with no obligation via WhatsApp or the form.
What if I have questions during the process?+
Our team supports you from start to finish via WhatsApp, phone or email, and the notary answers all your legal questions before signing.
