Error: Non-identified recipient
If when completing an information declaration, when including the data of a recipient or declared person, the message "Error: "Unidentified recipient" means that it is not possible to send the registration data in this way, since it does not match the data in the Tax Agency's census.
To check if a NIF appears in the AEAT census, use the option available on the website in the "Census, NIF and tax address" block in the "Information and procedures" section. In the "Highlighted procedures" box, click on "All procedures" to access the rest of the options, and click on "Checking a NIF for census purposes". Access is available with a certificate/ electronic ID or with Cl@ve. Once in the form, go to the "Unit consultation" section and indicate the NIF and the full surname and name in that order. Click on "Check"
In the event that the data entered in the surname field is not completely correct but the minimum percentage of matches is exceeded, the system will return the following message: "The person consulted has not been identified with the name provided, but there is similarity with the name registered in the AEAT census" and the complete census data.
In this case, you will have to enter the recipient's details in the information declaration as they appear in the census for the declaration to be accepted.
If this query still shows that the taxpayer has not been identified, try changing the order of the name or trying only part of it to see if there is a match.
