Peru RUC lookup
Type a Peruvian tax ID (RUC) to see what SUNAT's public registry has on file: the legal name, whether the company is active, whether SUNAT can locate it at its fiscal address, and a pass, review or fail verdict with the reasons in English.
No account needed: 10 lookups a day per network, shared with the keyless API. Company RUCs start with 20. Examples: 20100047218, 20272209325.
What the lookup shows
| Field | What it tells you |
|---|---|
| Legal name | The name the company is registered under with SUNAT. It should match your contract and invoice. |
| Status | Whether the RUC is active (ACTIVO) or deregistered, suspended or annulled. All status codes. |
| Address condition | HABIDO if SUNAT can locate the company, NO HABIDO or NO HALLADO if not. What it means. |
| Fiscal address | Street address with district, province and department. |
| Verdict | Pass: active and HABIDO. Review: active but the address is not verified, activities are suspended, or the RUC is not in our latest registry copy. Fail: wrong check digit, or deregistered, annulled or disabled. |
| Registry copy | The date of the SUNAT file the answer came from. |
Individuals and privacy
RUCs that start with 10, 15, 16 or 17 belong to individuals. For those we only check that the number and its check digit are valid, and show no name or address, in line with Peru's Personal Data Protection Law (Ley 29733). Some older company RUCs are registered under a person's name; for those we show the status, address condition and district but withhold the name and street.
Checking many suppliers?
The same data is available as a REST API and a remote MCP server for AI agents. An API key allows 100 lookups a day. See the API docs or the API overview, and read the supplier verification checklist for the full process.
