What the ISSEG (Instituto de Seguridad Social del Estado de Guanajuato) addenda is

It is a block of commercial data that ISSEG (Instituto de Seguridad Social del Estado de Guanajuato) asks for inside your invoice XML to find their order and pay you. It goes after the stamp, so it doesn't change the CFDI's validity with the SAT.

Government agencies and state-owned companies receive the invoice together with contract and delivery data. The addenda puts that data inside the XML so the payments team can check it without separate documents.

Data it usually asks for

  • Contract or order number
  • Supplier code or number
  • Receiving area, unit or warehouse
  • Delivery note or receipt number
  • In healthcare, sometimes the supply code

Each company defines its own addenda. The exact fields are in the manual your buyer or the ISSEG (Instituto de Seguridad Social del Estado de Guanajuato) accounts payable team gives you.

How much does the ISSEG (Instituto de Seguridad Social del Estado de Guanajuato) addenda cost?

Does the ISSEG (Instituto de Seguridad Social del Estado de Guanajuato) addenda affect the stamp?
