Since September 26 Your Electronic Invoices Must Carry Your System Provider's RUC: What to Check Today
As of September 26, 2026, the electronic invoices your company issues must carry a new piece of data: the RUC (tax ID) of the provider of the system used to generate them. This is required by SRI resolution NAC-DGERCGC26-00000027, signed on July 27 and published in the Fifth Supplement of Official Register No. 335 on July 28, according to Lexis and AVL Abogados. The 60-calendar-day deadline from publication ended today.
What changed
The resolution does two things. First, it creates a registry of providers of electronic invoicing systems and services: those who develop and own the code of these systems, or hold licenses for third-party systems, and sell them, had to register or update their RUC with a dedicated establishment and economic activity (CIIU codes J62021002 for developers and J62021003 for resellers of third-party systems) within 30 calendar days, that is, by late August.
Second, it requires issuers — the companies and individuals who invoice — to include, in the additional information section of every electronic document, the RUC of the invoicing system or service provider they use. That is the 60-day deadline that ends today. According to the same resolution, starting in October the SRI will publish the list of registered providers on its website, updated monthly within the first 10 business days.
One clarification: in recent days some outlets mentioned October 22 as the deadline for issuers. The text of the resolution, as reported by Lexis and AVL, refers to 60 calendar days from July 28, which lands on September 26. If you are unsure about your case, confirm with your accountant or directly with the SRI.
What your company should do today
- Check an invoice issued today. Open the XML or the RIDE (the printed representation) and look in the additional information for a field with your provider's RUC, usually labeled "RUC Proveedor".
- If it is missing, call your provider. In most commercial systems the field is added through an update or a setting; you should not have to type it by hand on every invoice.
- Ask whether they are registered. From October you will be able to check it on the SRI's list. A provider that did not register is exposed to penalties and left off the official list, according to Coronel & Pérez.
- If your system is in-house, built only for your own company's use and not sold to others, you do not become a provider required to register: the obligation depends on the commercial purpose, according to the analyses by AVL and Coronel & Pérez.
Why the SRI is doing this
Electronic invoicing is already the core of tax control: SRI director Alexandra Navarrete told El Universo that between 90% and 94% of transactions are transmitted to the SRI in real time. Identifying who runs the platforms that generate those documents gives the SRI a direct channel with providers when there are failures, technical-spec changes or non-compliance.
For an SME the lesson is practical: your invoicing system is no longer an administrative detail, it is a regulated component. It pays to know who maintains it, how it is updated and what happens if one day it stops complying.
