How to spot a fake or altered DODA

Warning signs

• The printed license, pedimento or customs section differs from the QR code.
• The integration number is missing from SAT's lookup or returns a different operation.
• Mismatched fonts, alignment or spacing within a single PDF field.
• A QR code pasted on top of the document or at a different quality than the rest.
• The document arrived through an unusual channel or with unusual urgency.

Cross-check QR, PDF and SAT

DODA Verify runs this comparison automatically with field-by-field rules. It takes three sources: the QR content, the printed text extracted from the PDF and SAT's public lookup response. It compares the integration number, license, pedimento and customs section, normalizing formats (such as leading zeros) to avoid false alarms.

Each difference shows the document value, the reference value and its source, and is rated critical or warning. A field that could not be read is never counted as a mismatch.

What to do if it does not match

1. 1Hold the truckPause the crossing until the difference is cleared up.
2. 2Keep the evidenceSave the original PDF, the QR photo and the verification result.
3. 3Call your customs brokerAsk them to confirm the operation and, if needed, issue a correct DODA.
4. 4Verify againScan the new document before releasing the trip.

Responsibilities

DODA Verify's result is an automated support check based on publicly available information. It is not a legal opinion and does not replace your customs broker's or the authority's review. The decision to clear remains with the parties to the operation.
