Pedimento
The pedimento is the Mexican customs document that backs the import of goods, and its fifteen-digit number goes on the CFDI, Mexico's electronic invoice, when those imported goods are sold first-hand.
Annex 20, the technical standard of the SAT (Mexico’s tax administration) for the CFDI, sets how that number is written. According to the SAT’s CFDI 4.0 filling guide, accessed October 17, 2026, it carries the last two digits of the validation year, two for the customs office of clearance, four for the patent number (patente) and seven more: the last digit of the current year, with exceptions for consolidated pedimentos and rectifications, followed by six for the progressive numbering of each customs office. That makes 2 + 2 + 4 + 7 = 15 digits in four groups separated by two spaces, as in the guide’s example: 10, 47, 3807 and 8003832.
The SAT asks for it on two documents. On the invoice, the customs information node of each line carries the number when imported goods are sold first-hand and the CFDI has no foreign trade complement. On the Carta Porte, according to the complement’s schema, the import pedimento number accredits the legal stay and possession of foreign goods while they are moved within Mexico.
In Odoo 20, the number is captured on the landed cost of the receipt, is tied to the lot or serial number and flows to the lines of the sales invoice, as the Mexican localization guide explains.
