Mexico DNC Scrubbing for US Outbound Teams

DNC LATAM · Compliance guides

Mexico operates an official Do Not Call system for consumers who do not want to receive advertising calls or messages. Companies marketing to Mexican numbers are expected to check the current registry before each campaign. The obligation also applies to foreign callers, with per-contact exposure when a registered number is reached.

What the registry covers

  • Consumers can register landlines and mobile numbers for free, by phone or online. Registration does not expire automatically.
  • It applies to marketing calls and messages across regulated commercial sectors and to the advertising use of consumer contact data.
  • The official data is updated and published every 15 days.

How companies are supposed to access it

Registry extracts are distributed to registered companies zone by zone, priced per geographic area and period through a Spanish-language portal. Covering all of Mexico means acquiring and re-downloading dozens of files every cycle, indefinitely. That administrative load is why most foreign companies do not manage the process directly. We documented the workflow in our guide to accessing Mexico's official DNC data.

Penalties for calling registered numbers

Mexico can fine companies for each call or message to a registered number under federal consumer-protection rules. Consumers can submit complaints online, and enforcement actions against telemarketers are published regularly. For an outbound operation dialing thousands of Mexican numbers, an un-scrubbed list creates open-ended exposure.

How foreign companies comply in practice

  1. Scrub every list against the current official release before dialing, never against a copy older than one 15-day cycle. New to the process? Start with our DNC scrubbing guide.
  2. Keep dated evidence of which registry release each campaign was checked against.
  3. Honor direct opt-outs regardless of registry status.

DNC LATAM maintains the required access, acquires every zone, and consolidates each official release behind one API, with CSV in the panel if you are not wiring code yet. Independent allowance and dated certificates for each selected country. Official government data, zero paperwork on your side.

The same API covers Argentina and Colombia. Change the country field when the campaign moves. Pricing stays an independent SKU per country. Spain, Australia, and Singapore are planned product coverage, end of September 2026. They are not at checkout today.
