SMS Compliance in Uruguay
A practical overview of the rules that affect SMS messaging and marketing in Uruguay, with a checklist before you launch.
Key Rules for SMS in Uruguay
Marketing messages in Uruguay must respect the Personal Data Protection Law 18.331, which requires consent and lets people object to marketing, supervised by the URCDP.
In North America, business texting is shaped by carrier rules as well as law: in the US, application-to-person messaging on standard numbers generally requires brand and campaign registration (10DLC), and the TCPA requires appropriate consent. Other countries in the Americas have their own consumer protection and data laws.
Data Protection
The Regulatory and Control Unit for Personal Data (URCDP) supervises Law 18.331, and databases must be registered.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Collect and record consent (or confirm an existing customer relationship) before sending, with the date and source.
- Use a registered sender ID or number that recipients can recognise as your business.
- Identify your business in every message and keep promotional and service messages separate.
- Give a simple way to opt out of marketing and process opt-outs quickly across all your systems.
- Send in the recipient's local daytime hours and keep frequency reasonable.
Contact data
Format numbers in international E.164 format with the +598 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Uruguay follows the America/Montevideo time zone (UTC-03:00 in October 2026). The usual working week is Monday to Friday. Schedule SMS campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Montevideo, customers commonly use Spanish. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Uruguay
Uruguay has some of Latin America's highest internet penetration, and WhatsApp is the main messaging app. Law 18.331 on personal data protection, overseen by the URCDP, requires consent for marketing.
Cards and debit payments are widespread, and many people pay through local networks such as Abitab and RedPagos. Carnival, the summer beach season in Punta del Este and Christmas are key periods.
Uruguay is known for political stability and strong digital infrastructure: the state-owned operator Antel has brought fibre to most homes, and the Plan Ceibal programme gave every school pupil a laptop. Software and IT services exports, beef, soybeans, pulp mills and tourism are key sectors. The EU recognises Uruguay's data protection law (Law 18.331) as adequate, which eases data transfers. The basic VAT rate is 22%, and prices are in Uruguayan pesos, though property and cars are often quoted in US dollars.
Regulators, Registers and Practical Rules in Uruguay
Uruguay's personal data law, Law 18.331, is supervised by the URCDP (Unidad Reguladora y de Control de Datos Personales), and the EU recognises Uruguay as providing adequate protection. Databases must be registered with the URCDP, and marketing requires consent or another legal basis, with the right to opt out. Telecoms are regulated by URSEC. Antel, the state operator, leads the mobile market, alongside Movistar and Claro.
Uruguayans are wary of exaggerated claims, so clear and sober messages work best. WhatsApp is used for almost all communication, and fibre broadband reaches most homes. Tourism Week, in the week before Easter, and the long summer holidays in January change response patterns, with many people on the coast. Prices in pesos should state whether VAT (22 per cent standard rate) is included.
