Mexico — Education Certificate (folio)

Validates a Mexican electronic education certificate by folio against the official education-certificate registry. Optionally send fullName or curp to confirm the certificate belongs to that person. When both are sent, curp wins. A mismatch returns 409 name_mismatch.

This checks the certificate record. It does not prove identity on its own. For a CURP civil record, see Mexican Citizen (CURP). For a professional license, see Professional License.

Notes

• folio is required. fullName and curp are optional owner checks. When both are sent, curp is used and fullName is ignored.
• A folio that is not in the registry returns 404. A name or CURP that does not belong to that certificate returns 409 name_mismatch.
• Results are cached for up to 7 days.
• Sandbox folio SIGED10000001 returns the sample certificate for ANA LOPEZ RUIZ. fullName=Ana Lopez Ruiz also returns 200.
• fullName=Maria Perez on that folio returns 409 name_mismatch.
• Folio FOLIO90040401 returns 404.
• curp=LOPE900501HDFGRN01 with any fullName returns 200, because CURP wins. curp=LOPE900404HDFNTF01 returns 404.
• A missing folio returns 409 MissingParameter.
• When the registry cannot be reached, the response is 409 Endpoint_out_of_service. Retry later.
