DNC Scrubbing: Check REPEP, No Llame, and RNE First
DNC LATAM · Compliance guides
Updated 23 September 2026
DNC scrubbing is the check that removes numbers already on an official Do Not Call registry before anyone dials. Mexico is REPEP (PROFECO). Argentina is the Registro Nacional No Llame (AAIP). Colombia is RNE (CRC). A US National DNC wash misses all three. DNC LATAM sells the scrub as an API or a CSV. Talk to us. API.

How DNC scrubbing works
- You send the list, typically through a DNC API wired into the dialer or CRM, or as a CSV upload in the panel if ops is not shipping code yet.
- The list is matched against the registry. Every number is compared to the current official Do Not Call data for the destination country.
- Registered numbers are flagged or removed. You get back the numbers not found on the selected registry, plus a record of what was suppressed.
- A screening record documents the scrub, a dated record of which registry release the list was checked against, plus counts. It does not contain phone numbers. The product page is screening records. The how-to is what auditors ask for.
Why a DNC checker matters
Regulators fine per violation, not per campaign. In the US, TCPA damages run $500-$1,500 per call, while authorities in other destination countries can also sanction calls to registered numbers. A single un-scrubbed campaign of a few thousand calls can cost more than a decade of a DNC scrubbing service. Estimate your exposure with our fine calculator. Bulk scrubbing clears a whole list before launch. For one-off lookups on leads that arrive after that point, see our guide to using a DNC checker for Mexico and Argentina.
Scrubbing frequency: how often is enough?
Registries change constantly, and Mexico publishes a new official release every 15 days. The accepted standard is to scrub against the most recent registry release before every campaign, and never rely on a scrub older than 30 days. US rules under the TSR require using a registry version no older than 31 days.
LATAM scrubbing is not a US TCPA scrub
A LATAM DNC scrub means checking the destination country's own official registry: Mexico REPEP (PROFECO), Argentina Registro Nacional No Llame (AAIP), and Colombia RNE (CRC). It is not a check against the US National DNC Registry and it does not satisfy TCPA rules for US numbers. US vendors built around the FTC list leave +52, +54, and +57 numbers unchecked. That gap is the whole DNC scrubbing vs US TCPA page.
DNC scrubbing beyond the US
Most DNC scrubbing services cover the US registry, and the larger ones add the UK, Canada and Australia. Latin America is the usual blind spot: Mexico REPEP, Argentina No Llame, and Colombia RNE operate mandatory registries with real enforcement, but their data is published only through local government channels, in Spanish, with local registration requirements. See our guides to Mexico REPEP / PROFECO, Argentina No Llame / AAIP, and Colombia RNE / CRC, or the overview of international DNC lists. Nearshore floors: DNC for contact centers.
