How to check a Spanish animal association’s tax ID (CIF)
We check that the CIF has the shape set by Orden EHA/451/2008 and tell you which type of entity its letter indicates. It is a format check, not an ownership check.

What it checks
- Which type of entity the first letter indicates (G is for associations).
- That the length and format are those of a Spanish CIF.
What it does not check
- The check character: no published rule explains how it is computed, so we do not assess it.
- That this CIF belongs to the organisation whose name you were given.
- That the organisation still exists or is up to date with its obligations.
- Anything about its actual activity.
How to read a CIF
- The first letter gives the legal form: G is an association; A and B are companies.
- Seven digits follow.
- The last character is the check character. How it is computed is not in any published rule, so we do not check it.
Frequently asked questions
Why don’t you check the check character?
We only use rules published by the administration. Orden EHA/451/2008 says there is a check character but not how it is computed.
Does a CIF starting with B rule out a shelter?
It rules out nothing: it means the legal form is a company, not an association. It is a fact you can ask about, not a conclusion.
Do you check whether the CIF really exists?
No. We only check that the number is well built. To know who it belongs to, look it up in the register of associations.
