Ecuador RUC Checker

Consultar RUC: check an Ecuadorian RUC against the SRI taxpayer register and see its status, with the registered name after sign-up.

What is an Ecuadorian RUC?

The RUC (Registro Único de Contribuyentes) number is Ecuador’s 13-digit tax identification number, issued by the Servicio de Rentas Internas (SRI). It starts with a 2-digit province code and always ends in 001 — for example 1790016919001 for Corporación Favorita C.A. For individuals with a cédula, it is the cédula followed by 001.

  • 13 digits: Numbers only, with no letters, separators or EC prefix.
  • Individuals: The 10-digit cédula plus 001 — personal data, so this page uses company examples only.
  • No check digit promise: Newer company RUCs are plain sequences, so only the register can confirm a RUC.
  • Status: A found RUC shows its SRI status. Only ACTIVO means the taxpayer is operating; SUSPENDIDO and PASIVO RUCs are still found.

Frequently Asked Questions

How do I check if a RUC is active? (¿Cómo saber si un RUC está activo?)

The SRI register records each taxpayer as ACTIVO, SUSPENDIDO or PASIVO; only ACTIVO means the taxpayer is currently operating. Among other cases, the SRI can suspend a RUC on its own initiative when the taxpayer has shown no economic activity for 12 months. Our checker shows the status.

What is the difference between the cédula and the RUC?

For Ecuadorians and resident foreigners, the RUC is the 10-digit cédula followed by 001. Only people with economic activity or taxable income or assets must register, so many cédula holders have no RUC.

What does 001 at the end of the RUC mean?

The last three digits are 001 for every taxpayer. Branches do not get RUCs ending 002 or 003; they are registered as numbered establishments under the same RUC.

What does the third digit of the RUC mean?

9 marks a company, or a foreigner without a cédula (the SRI assigns these numbers), and 6 a public entity. For individuals with a cédula the third digit is simply that of the cédula — usually 0 to 5, though 6 also occurs.

Does the Ecuadorian RUC have a check digit?

RUCs built from a cédula carry the cédula’s check digit. For companies the SRI has not published an algorithm, and RUCs issued since about 2021 do not follow the older mod-11 pattern, so only a register lookup can confirm a RUC.

What is RUC 9999999999999?

It is not a taxpayer. It is the code the SRI requires on electronic invoices for anonymous sales to a consumidor final.
