Voice Call Compliance in Mexico

Key Rules for Voice Calls in Mexico

Consumers can register on PROFECO's REPEP list to block marketing calls and messages, and telemarketing campaigns must respect it.

Automated and prerecorded calls are tightly regulated in the US (TCPA and the National Do Not Call Registry) and Canada (CRTC Unsolicited Telecommunications Rules), and other countries in the region have their own registers and rules.

Practical Checklist

• Check whether the call is promotional or a service call, as the rules differ.
• Use permitted calling numbers and caller ID, and never hide or spoof the calling number.
• Screen numbers against any national do-not-call register before promotional campaigns.
• Call only within permitted hours in the recipient's time zone and keep recorded messages short.
• Offer an easy way to stop further calls and record call consent where required.

Contact data

Format numbers in international E.164 format with the +52 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.

Digital Habits and Channels in Mexico

Mexico is one of WhatsApp's largest markets, and customers routinely use it to ask questions, book appointments and confirm orders; Facebook, Instagram and TikTok drive discovery. SMS remains common for codes and reminders.

Cards, cash payments at OXXO convenience stores, SPEI bank transfers and Mercado Pago are widely used, and monthly instalments without interest (meses sin intereses) are a strong purchase driver. El Buen Fin in November, Hot Sale in spring, Día de las Madres on 10 May, back-to-school and Christmas are key periods. A new federal personal data protection law took effect on 21 March 2025, replacing the 2010 law.

Mexico is closely linked to the US economy through the USMCA trade agreement, with car and auto parts plants, aerospace suppliers, electronics assembly and maquiladoras concentrated in the northern and Bajío states, and nearshoring has brought new investment. Remittances, tourism, oil and agriculture (avocados, tomatoes, berries and tequila) are also important. VAT (IVA) is 16%, with 8% in the northern and southern border zones. Consumers can register numbers in PROFECO's REPEP to block advertising calls and messages. Cash at OXXO convenience stores, cards and SPEI bank transfers are the main payment methods.

Advertising Alongside Messaging

Advertising must follow the Federal Consumer Protection Law, and health-related products are subject to COFEPRIS advertising rules.
