This article is only relevant when the country in which the employee pays their social security contributions (home country/payroll country) is Spain.
Applying for A1 certificates in Spain is done online through the Seguridad Social portal. The process is relatively structured, but the main challenge is that each Spanish region can have slightly different practices, which sometimes leads to delays or additional requests. Processing usually takes 2–4 weeks, but in some regions it can take longer.
✅ What you need to do
1. Sign a Power of Attorney (POA)
We will provide you with a POA template. Please sign it and return it to us. Please fill properly the CCC (Código Cuenta de Cotización), the 11-digit number issued by Spain’s Social Security authority (TGSS) that identifies a company or self-employed employer. It works like the employer’s “ID number” and it is required to apply for the A1s.
2. Grant WorkFlex authorization on the Seguridad Social portal
Your entity must authorize WorkFlex as your representative within the portal.
During onboarding, we’ll share a step-by-step guide to complete this authorization.
⚠️ Key points to bear in mind
A POA is always required.
Without Seguridad Social authorization, WorkFlex cannot submit applications.
Processing times can vary by region (2–4 weeks on average).
A1s are sent to the main RED account. In order to upload them into WorkFlex, you’ll need to share the document with us. We recommend sending it via password-protected ZIP to [email protected], or let us know if you prefer another secure method.
👉 Once the POA and authorization are in place, WorkFlex will handle your Spanish A1 applications end-to-end.
