Tired of sales calls constantly interrupting your workday in Colombia?
You can stop them. The tool is called the Registro de Numeros Excluidos (RNE), a centralized government platform run directly by the Communications Regulation Commission (Comision de Regulacion de Comunicaciones, or CRC). It costs nothing to use. Under Law 2300 of 2023, the system lets mobile and landline subscribers revoke commercial contact permissions across phone calls, text messages, messaging apps, and email.
This platform applies strictly inside Colombia. It has nothing to do with U.S. Federal Trade Commission (FTC) rules, nor will it wipe out standard account alerts from your utility or bank. Knowing how the registry operates helps you set clear boundaries and take action when pushy vendors ignore the rules.
Legal Scope and How the Registry Operates
Colombians widely refer to Law 2300 of 2023 as the "Ley Dejen de Fregar." The statute protects personal rest hours and individual privacy by restricting how and when businesses reach out for sales or debt collection. To enforce this, the CRC overhauled its older framework in Resolution CRC 5050 of 2016 by passing Resolution CRC 7356 of 2024. Commercial entities are barred from contacting registered consumers for promotional campaigns, product launches, customer acquisition, or general marketing.
The registry used to be tiny. Before April 10, 2024, it only blocked SMS advertising.
The CRC then widened the net across four distinct paths: voice calls to cell phones and landlines, standard SMS, web and app messaging like WhatsApp, and direct email.
Turns out, signing up carries serious legal weight. Analysis by Perez-Llorca highlights an external circular issued by the Superintendence of Industry and Commerce (Superintendencia de Industria y Comercio, or SIC) in 2024. That circular established that signing up on the RNE automatically wipes out any marketing consent you gave a merchant in the past.
Retailers often bury permissions inside store reward programs or routine purchase agreements. Putting your phone number or email into the RNE cancels those old authorizations on the spot. Companies, aggregators, and marketing agencies must check the CRC database before launching campaigns. If you agreed to promo texts two years ago, enrolling your line on the RNE overrides that permission by law.
Step-by-Step Guide to Enrolling and Managing Channel Preferences
The entire registration runs online. It costs zero dollars ($0). The CRC never charges a fee, and no third-party middleman has authorization to collect cash for it.
Follow these steps to submit your lines and customize your contact boundaries:
- Access the Official Government Portal: Head to the administrative site at Tramites CRC. Steer clear of commercial portals offering fake paid shortcuts.
- Create and Authenticate Your Profile: Set up your account using an official ID. The site takes a national identity card (cedula de ciudadania), foreign resident card (cedula de extranjeria), or valid passport. You must provide a valid email address to verify the account and receive system alerts.
- Open the RNE Module: Once logged in, open the Registro de Numeros Excluidos tool from your main user dashboard.
- Input Your Contact Channels: Enter the exact details you want protected. You can add Colombian mobile numbers, landlines with their area codes, and personal email addresses.
- Select Channel-Specific Preferences: Pick your opt-out settings for every phone line or email. You can block voice calls, SMS, messaging apps, and email all at once, or leave specific channels open for certain interactions.
- Submit and Download the Registration Certificate: Finish the submission and save your official confirmation certificate (constancia de inscripcion). It shows your timestamp, registered lines, and selected exclusions. Keep this PDF file on your computer. It is your primary proof if a vendor breaks the rules later.
Did you sign up before April 10, 2024? Your old listing only shields against SMS spam under the previous rules. To block voice telemarketing, app messaging, and marketing emails, you need to log in and select those extra channels manually.
Blocking does not happen instantly. Aggregators and content providers have up to 5 business days to download updated CRC files, sync their databases, and halt marketing campaigns. If you send a written petition (derecho de peticion) directly to an individual company demanding list removal, they have up to 15 business days to deliver a formal written response under Colombian administrative law.
Communications Comparison: Marketing Outreach vs. Exempt Communications
Getting a call after enrolling does not mean the system crashed. The RNE only filters commercial pitches. It leaves transactional notices, service messages, and collections untouched.
| Communication Category | RNE Block Status | Legal Basis / Permitted Contact Hours | Allowed Outreach Types | Prohibited Practices |
|---|---|---|---|---|
| Commercial & Advertising | Blocked upon registration (up to 5 business days for SMS sync) | Law 2300 of 2023; Resolution CRC 5050 of 2016 (amended by Resolution 7356 of 2024). Permitted hours: Mon-Fri 07:00-19:00, Sat 08:00-15:00. | Promotional offers, credit card pitches, retail sales discounts, cellular plan upgrade offers, cold sales outreach. | Contact on Sundays and national public holidays; contact outside statutory daytime hours; contacting lines listed in the RNE. |
| Transactional & Operational | Exempt (Not blocked by the RNE) | Resolution CRC 5050 of 2016; underlying service contracts and terms of service. | Security one-time passwords (OTPs), fraud alerts, monthly account balance statements, carrier network disruption notices. | Using operational alert channels to bundle hidden commercial advertisements or sales promotions. |
| Debt Collection ("Cobranza") | Exempt (Not blocked by the RNE; governed by separate statutory caps) | Law 2300 of 2023. Permitted hours: Mon-Fri 07:00-19:00, Sat 08:00-15:00. Frequency limit: Maximum of two successful contacts per calendar week across a single agreed-upon channel. | Overdue loan notices, formal collection agency outreach, payment agreement structuring, credit card default reminders. | Contacting friends or personal references; calling more than twice per week; outreach on Sundays or holidays; abusive or threatening contact. |
Marketing teams have narrow contact windows. Legal reporting by Garrigues emphasizes that sales outreach can only take place Monday through Friday between 7:00 AM and 7:00 PM, and Saturdays from 8:00 AM to 3:00 PM. Outbound pitches are completely forbidden on Sundays and Colombian national holidays.
Debt collection (gestion de cobranza) follows its own rulebook under Law 2300 of 2023. Thing is, an overdue balance gives collectors legal clearance to call you even if your number sits on the RNE. They must stick to the same daytime hours as sales teams, and they cannot reach out more than twice a week on your agreed channel. You simply cannot use the RNE to dodge legitimate collection agencies.
Escalating Violations: Documenting Evidence and Filing SIC Complaints
Did a company pitch you after the 5-day grace period? You can take them straight to the Superintendence of Industry and Commerce (SIC).
The SIC handles national consumer protection, data privacy breaches, and Law 2300 violations. Investigators need hard proof before opening a formal inquiry, so assemble a clear record:
- Caller Identification: Unaltered screenshots showing the incoming phone number, alphanumeric short code, or sender email address.
- Date and Time Records: Detailed call logs and timestamps proving the outreach arrived after the 5-day cutoff or outside legal hours.
- Content Records: Screenshots of SMS messages, email headers with full message bodies, or voice recordings of the product pitch.
- Corporate Entity Details: The company name, commercial brand name, or national tax ID (Numero de Identificacion Tributaria, or NIT) mentioned during contact.
- CRC Registration Certificate: The downloaded PDF constancia verifying the exact date you enrolled your line.
File your paperwork through the SIC Radicacion Virtual web portal. Staff check whether the company queried the CRC database and whether they respected the 5-business-day timeline.
Penalties can hit hard. Fines reach up to 2,000 legal monthly minimum wages (Salarios Minimos Legales Mensuales Vigentes, or SMLMV). The agency can also suspend marketing data processing for up to 6 months. Remember that these administrative fines go straight into national treasury accounts, meaning your complaint will not generate a personal payout, bounty, or settlement check.
Frequently Asked Questions
Can registering on the RNE stop collection agencies from calling about an outstanding debt?
No. The RNE only covers marketing, sales pitches, and promotional campaigns. Debt collection falls under separate sections of Law 2300 of 2023. While collection reps must respect daytime hours (Monday-Friday 07:00-19:00, Saturday 08:00-15:00) and cannot contact you more than twice per week across your chosen channel, registering does not wipe out a creditor's right to pursue an unpaid bill.
Do users who registered their phone numbers before April 2024 need to re-register?
Yes, if you want full coverage. Old registrations handled before April 10, 2024, only blocked promotional SMS text messages. To stop marketing calls, app messages, and promotional emails, you have to log into the CRC platform and check those channel boxes yourself.
How does the registry handle calls from spoofed numbers or unidentified commercial entities?
The registry relies on compliant, formal businesses pulling exclusion records before dialing. Rogue operators, overseas call centers, and scammers using spoofed caller IDs deliberately bypass those checks. As El Tiempo reported, the CRC has introduced technical regulations to help telecom operators spot suspicious network traffic and crack down on spoofed caller numbers.
How long does a company have to stop contacting me once I register on the RNE or submit a direct petition?
Companies and aggregators get up to 5 business days after your RNE registration to download the updated list and pause marketing campaigns. If you bypass the registry and submit a formal written petition (derecho de peticion) directly to a merchant to revoke consent, they have up to 15 business days under Colombian administrative law to process your request and issue a written answer. If calls persist past day five of your RNE sign-up, pull your phone logs and file your complaint directly through the SIC portal.
